+x11vnc 0.9.13 2010-12-20
+
+New in the 0.9.13 x11vnc release:
+
+ Improved support for non-X11 touchscreen devices (e.g. handheld or
+ cell phone) via Linux uinput input injection. Additional
+ tuning parameters are added. TSLIB touchscreen calibration
+ is supported. Tested on Qtmoko Neo Freerunner.
+
+ A tool, misc/uinput.pl, is provided to diagnose uinput
+ behavior on new devices.
+
+ The env. vars. X11VNC_UINPUT_BUS and X11VNC_UINPUT_VERSION
+ are available if leaving them unset does not work.
+
+ The Linux uinput non-X11 input injection can now be bypassed:
+ events can be directly written to the /dev/input/event
+ devices specified by the user (direct_abs=..., etc.)
+
+ A -pipeinput input injection helper script,
+ misc/qt_tslib_inject.pl is provided as a tweakable
+ non-builtin direct input injection method.
+
+ The list of new uinput parameters for the above two features is:
+ pressure, tslib_cal, touch_always, dragskip, btn_touch;
+ direct_rel, direct_abs, direct_btn, direct_key.
+
+ The included SSL enabled Java VNC Viewers now handle Mouse
+ Wheel events.
+
+
+ miscellaneous new features and changes:
+
+ In -reflect mode, the libvncclient connection can now have
+ the pixel format modified via the environment
+ variables X11VNC_REFLECT_bitsPerSample,
+ X11VNC_REFLECT_samplesPerPixel, and
+ X11VNC_REFLECT_bytesPerPixel
+
+ In -create mode the following environment variables are added
+ to fine tune the behavior: FIND_DISPLAY_NO_LSOF:
+ do not use lsof(1) to try to determine the Linux VT,
+ FIND_DISPLAY_NO_VT_FIND: do not try to determine the
+ Linux VT at all, X11VNC_CREATE_LC_ALL_C_OK: do not bother
+ undoing the setting LC_ALL=C that the create_display
+ script sets. The performance of the -create script
+ has been improved for large installations (100's of
+ user sessions on one machine.)
+
+ In -unixpw mode, one can now Tab from login: to Password.
+
+ An environment variable, X11VNC_SB_FACTOR, allows one to scale
+ the -sb screenblank sleep time from the default 2 secs.
+
+ In -rawfb mode, a bug is fixed in setting the number of bits
+ per pixel.
+
+ Documented that -grabkbd is no longer working with some/most
+ window managers (it can prevent resizing and menu posting.)
+
+ The macosx deprecated interface GetMainDevice() call is removed.
+ Compile with -DX11VNC_MACOSX_USE_GETMAINDEVICE if needed
+ for an old macosx version...
+
+ Miscellaneous code cleanup.
+
+-----------------------------------------------------------------------------
+
+
+x11vnc 0.9.12 2010-09-10
+
+New in the 0.9.12 x11vnc release:
+
+ One can now specify the maximum number of displays
+ that can be created in -create mode via the
+ env. var. X11VNC_CREATE_MAX_DISPLAYS
+
+ The X11VNC_NO_LIMIT_SHM env. var. is added to skip any
+ automatic shared memory reduction.
+
+ The kdm display manager is now detected when trying not to get
+ killed by the display manager.
+
+ miscellaneous new features and changes:
+
+ A compile error is fixed when using --with-system-libvncserver
+ pointing to LibVNCServer 0.9.7.
+
+ -nevershared -forever usage mode is documented.
+
+ Old SuSE broken thread local storage is documented.
+
+ x11vnc exit cases are documented.
+
+ A compile bug from forced use of Xdefs.h is worked around.
+
+
+-----------------------------------------------------------------------------
+
+
+x11vnc 0.9.11 2010-08-08
+
+New in the 0.9.11 x11vnc release:
+
+ The source tree is synchronized with the most recent libvncclient
+ (this only affects -reflect mode.) The build is fixed
+ for incompatibilities when using an external LibVNCServer
+ (e.g. ./configure --with-system-libvncserver...)
+
+ The SSL enabled Java VNC Viewer Makefile has been modified so
+ that the jar files that are built are compatible back
+ to Java 1.4.
+
+ In -reflect mode cursor position updates are now handled
+ correctly.
+
+ In -create/-unixpw mode, the env. var. FD_USERPREFS may be set
+ to a filename in the user's home directory that includes
+ default username:options values (so the options do not
+ need to be typed every time at the login prompt.)
+
+ miscellaneous new features and changes:
+
+ An option -always_inject is provided: Even if there is no
+ displacement (dx = dy = 0) for a VNC mouse event force
+ the pointer to the indicated x,y position anyway.
+
+ New java viewer debugging and workaround applet parameters:
+ debugKeyboard mapF5_to_atsign forbid_Ctrl_Alt
+
+ You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or
+ X11VNC_AVAHI_PORT environment variables to override the
+ default values. For example: -env X11VNC_AVAHI_NAME=wally
+
+ When opening the X11 display extra XAUTHLOCALHOSTNAME settings
+ are attempted.
+
+
+-----------------------------------------------------------------------------
+
+
+x11vnc 0.9.10 2010-05-03
+
+New in the 0.9.10 x11vnc release:
+
+ IPv6 is now supported for all usage modes: forward and reverse
+ connections, SSL and unencrypted, etc.
+
+ The included SSL enabled Java VNC viewer applet now supports
+ Chained SSL Certificates (x11vnc -ssl always has.)
+ The applet autodects x11vnc and set GET=1 for faster
+ connecting via HTTPS.
+
+ A demo CGI script 'desktop.cgi' shows how to create an
+ SSL encrypted, multi-user x11vnc web login desktop
+ service. The user logs into a secure web site and gets
+ his/her own virtual desktop and his browser accesses it
+ with the SSL Java VNC Viewer applet.
+
+ A serverCert Java Viewer applet parameter is provided.
+ Use an authenticated HTTPS browser connection to set
+ this parameter (the user could set it locally too.)
+ The onetimekey tool has -certonly option for this scheme.
+
+ The Xdummy script (use Xorg 'dummy' driver instead of Xvfb)
+ no longer requires being run as root.
+
+
+ miscellaneous new features and changes:
+
+ In the Java viewer applet, debugCerts and debugKeyboard parameters
+ are provided. The debugging output of the applet is more
+ readable. Some corner-case bugs (e.g. socket exceptions)
+ are now handled gracefully. Parameters forbid_Ctrl_Alt
+ and mapF5_to_atsign are added.
+
+ The amount of time to wait for HTTPS applet downloads to finish
+ can be set in env. var. X11VNC_HTTPS_DOWNLOAD_WAIT_TIME.
+
+ The -xkb mode is automatically enabled if there are more than
+ 4 keysyms per key.
+
+ -coe is now an alias for -connect_or_exit.
+
+ The -input_eagerly option enables this LibVNCServer feature
+ (it is like -allinput.)
+
+ The "%" unix password verification tricks for the -unixpw
+ option are now documented. They also run a command
+ in UNIXPW_CMD.
+
+ In -create (-svc, etc.) modes, a warning is printed out if Xvfb
+ cannot be found. Xvfb '+kb' option is checked for.
+ The -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt debugging
+ option is documented. Try to preserve user's PATH
+ if possible.
+
+ In XDMCP connection mode, a test for GDM listening only
+ on IPv6 (::1) is performed. The interface can also be
+ specified via FD_XDMCP_IF.
+
+ The example scripts connect_switch, ultravnc_repeater.pl, inet6to4
+ have settings to let them run reliably for long times
+ as daemons. They also support IPv6.
+
+ IPv6 notes: for some very esoteric cases (e.g. -chatwindow)
+ IPv4 localhost may be required for local IPC. A demo
+ transition tool 'inet6to4' is also included (can be
+ used for other apps.) x11vnc options related to IPv6:
+ -listen6, -6, -no6, -noipv4, -noipv6, and -connect,
+ -proxy.
+
+ Use STUNNEL_LISTEN in -stunnel mode to have it listen on a
+ particular interface. Also STUNNEL_PROG.
+
+ New remote control query options: pointer_x, pointer_y,
+ pointer_same, pointer_root, and pointer_mask. A demo
+ script using them misc/panner.pl is provided.
+
+ Remote control change of -clip option will not create new
+ framebuffer if the size has not changed (for panner.pl)
+
+ The X11VNC_DISABLE_SSL_CLIENT_MODE env. var. can be set to
+ disable SSL client role in reverse connections. This
+ means the VNC viewer side must be in SSL client role.
+ UltraVNC repeater operation can benefit from this.
+
+ The SSL_INIT_TIMEOUT is increased to 1 hour if 'repeater'
+ is detected in a reverse connect string.
+
+ The X property X11VNC_TRAP_XRANDR can be set on a desktop to
+ force x11vnc to use the -xrandr screen size change
+ trapping code.
+
+ The -sslScripts option prints out the SSL certificate management
+ scripts.
+
+ Suggest '-auth guess' and '-findauth' if X connection fails.
+
+ The TightVNC sercurity type (TightVNC features enabler) now
+ works for RFB version 3.8.
+
+ RECORD scroll detection is now working with the new gtk/gdk scroll
+ mechanism. Set X11VNC_SCROLL_MUST_EQUAL to disable.
+

+-----------------------------------------------------------------------------
+
+
+x11vnc 0.9.9 2009-12-21
+
+
+
+New in the 0.9.9 x11vnc release:
+
+ A new option -findauth runs the FINDDISPLAY script that applies
+ heuristics to try to determine the correct XAUTHORITY
+ file. The use of '-auth guess' will use the XAUTHORITY
+ that -findauth reveals. This can be handy in with
+ the lastest GDM where the ability to store cookies in
+ ~/.Xauthority has been removed.
+
+ If x11vnc is running as root (e.g. inetd or XDM/GDM/KDM)
+ the FD_XDM=1 mode will be tried if the above -findauth
+ or '-auth guess' command fails; it will find the
+ correct XAUTHORITY for the given display (this works for
+ XDM/GDM/KDM if the login greeter panel is up or if someone
+ has already logged into an X session.) You can also
+ set -env FD_XDM=1 to force it to be done on the first try.
+
+ The -unixpw_system_greeter option, when used in combined
+ unixpw and XDMCP FINDCREATEDISPLAY mode (e.g. -xdmsvc),
+ enables the user to press Escape to jump directly to the
+ XDM/GDM/KDM login greeter screen. This way the user
+ avoids entering his unix password twice at X session
+ creation time. For subseqent logins to the same session,
+ he uses the regular x11vnc unixpw "login:" prompt. Also,
+ the unixpw login panel now has a short help displayed
+ if the user presses 'F1' that lists the options.
+
+ The -appshare option enables simple application sharing based on
+ the -id/-sid mechanism. Every new toplevel window that
+ the application creates induces a new viewer window via
+ a reverse connection. The -id/-sid and -connect options
+ are required. Run 'x11vnc -appshare -help' for more info.
+
+ Heuristics are applied to try to determine if the X display
+ is currently in a Display Manager Greeter Login panel
+ (e.g. GDM.) If so, x11vnc's creation of any windows and
+ use of XFIXES are delayed.
+
+ This is to try to avoid x11vnc being killed after the user
+ logs in if the GDM KillInitClients=true is in effect.
+ So one no longer needs to set KillInitClients=false in
+ gdm.conf. Note that in recent GDM the KillInitClients
+ option has been removed.
+
+ Also delayed is the use of the XFIXES cursor fetching
+ functionality; this avoids an Xorg bug that causes Xorg
+ to crash right after the user logs in.
+
+ x11vnc now tries to be more aggressive in keeping up with VNC
+ client's framebuffer update requests. Some broken VNC
+ clients continuously spray these requests at VNC servers
+ (regardless of whether they have received any updates
+ or not.) The -extra_fbur option allows one to fine tune
+ the setting.
+
+ The "-display WAIT:cmd=...", -find, -create modes now work
+ correctly for the user-supplied login program scheme
+ "-unixpw_cmd ...", as long as the login program supports
+ running commands specified in the environment variable
+ "RFB_UNIXPW_CMD_RUN" as the logged-in user. The mode
+ "-unixpw_nis ..." has also been made more consistent.
+ The username option "tag=..." can be used to set FD_TAG.
+
+ The -stunnel option (like -ssl but uses stunnel as an external
+ helper program) now works with the -ssl "SAVE" and "TMP"
+ special certificate names. The -sslverify and -sslCRL
+ options now work correctly in -stunnel mode. Single port
+ HTTPS connections are also supported for this mode.
+
+ The remote control command -R can be used to instruct x11vnc
+ to resend its most recent copy of the Clipboard,
+ Primary, or Cutbuffer selections: "x11vnc -R
+ resend_clipboard", "x11vnc -R resend_primary", and
+ "x11vnc -R resend_cutbuffer".
+
+ miscellaneous new features and changes:
+
+ The fonts in the GUI (-gui) can now by set via environment
+ variables, e.g. -env X11VNC_FONT_BOLD='Helvetica -16 bold'
+ and -env X11VNC_FONT_FIXED='Courier -14'.
+
+ The value of the -timeout option is now also used for the timing
+ out of reverse connections. The -timeout exit will
+ occur if no client has made it to normal operating state
+ (instead of merely trying to connect.)
+
+ One can add extra URL parameters to the HTTPS (-ssl) urls
+ via X11VNC_EXTRA_HTTPS_PARAMS without needing to edit
+ index.vnc. E.g.: -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1'
+
+ One can make the libvncserver HTTP (non-SSL) server listen on
+ localhost: -env X11VNC_HTTP_LISTEN_LOCALHOST=1 (this way
+ only the single-port VNC+HTTPS is exposed to the network.)
+
+ Warnings are printed out at startup if $DISPLAY appears to
+ start with "localhost:" (SSH X11 forwarding) or
+ "hostname:" (remote X display; will fail w/o -noshm)
+
+ The -solid option now uses the DBUS_SESSION_BUS_ADDRESS env. var
+ if available. The -solid option now works in xfce.
+ If available, the dbus_launch(1) will be used in
+ FINDCREATEDISPLAY for gnome sessions.
+
+ The bcx_xattach remote control command was added to facilitate
+ xattach and x2x desktop cursor switching. Other new
+ remote control commands: grab_state, ping:mystring,
+ grablocal, resend_cutbuffer, resend_clipboard,
+ resend_primary, keycode, keysym, fakebuttonevent,
+ ptr, sleep, get_xprop, set_xprop, wininfo, pointer_pos,
+ mouse_xy, noop, guess_dbus, DIRECT:query. Remote control
+ scripting, -query_retries, and -remote_prefix were
+ also added.
+
+ In -rawfb mode the X display will not be opened at all unless
+ the -rawfb string is prefixed with '+' or -display
+ was specified on the cmdline.
+
+ For multiple, separate x11vnc instances on the same X display,
+ one can rename the X11VNC_REMOTE, X11VNC_TICKER, and
+ VNC_CONNECT property names to unique ones.
+
+ The -showrfbauth option prints out the VNC rfbauth password.
+
+ The XDAMAGE mechanism is now automatically disabled for a
+ period of time if a game or screensaver generates too
+ many XDAMAGE rectangles per second. This avoids the X11
+ event queue from soaking up too much memory.
+
+ x11vnc does not switch on server autorepeat if any keys are
+ pressed down to work around a recent Xorg server and/or
+ gnome bug where the key will never stop repeating.
+
+ Thse list of current clients is kept more up-to-date in the
+ tkx11vnc gui. Bugs in the gui setpass mode have been
+ fixed.
+
+ Threads stability is further improved. See under the -threads
+ option help info about -env X11VNC_THREADS_NEW_FB_SLEEP=ms
+
+ There is an experimental workaround: "-env X11VNC_WATCH_DX_DY=1"
+ that tries to avoid problems with poorly constructed
+ menu themes that place the initial position of the mouse
+ cursor inside a menu item's active zone.
+
+ The crypt(3) function is now declared inside the x11vnc code on
+ all platforms (not just Linux). To disable this, set
+ CPPFLAGS='-DDO_NOT_DECLARE_CRYPT' while configuring.
+ (crypt is declared to avoid problems with header files.)
+
+ Error reasons are printed for -storepasswd failures.
+
+ Two scripts are added to x11vnc/misc: connect_switch and
+ ultravnc_repeater.pl

+
+
+x11vnc 0.9.8 2009-07-08
+
+
+New in the 0.9.8 x11vnc release:
+
+ Better reliability for the Java Viewer applet when connecting
+ through a Web Proxy via HTTPS. A proxy hostname
+ and port can be specified via applet parameters.
+ Proxy Authentication via Auth-Basic is supported.
+ More x11vnc printout in -ssl is provided to help
+ troubleshoot this mode and other ssl connections.
+
+ Stability improvements to -threads mode. Running x11vnc this
+ way is more reliable now. Threaded operation sometimes
+ gives better interactive response and faster updates. The
+ threaded mode now supports multiple VNC viewers using
+ the same VNC encoding (some only on Linux or enabled
+ at build time.) The threaded mode can also yield
+ a performance enhancement in the many client case
+ (e.g. class-room broadcast.) We have tested with 30 to
+ 50 simultaneous clients. See also -reflect.
+
+
+ miscellaneous new features and changes:
+
+ x11vnc automatically tries to work around an Xorg server bug
+ involving infinitely repeating keys when turning off key
+ repeating. Use -repeat if the automatic workaround fails.
+ Also, the environment variable X11VNC_IDLE_TIMEOUT
+ (seconds) is provided.
+
+ In -reflect mode the environment variable X11VNC_REFLECT_PASSWORD
+ is provided.
+
+ The -clip mode works under -rawfb.
+
+ The -nounixpw option can disable unixpw mode if an earlier option
+ enables it (e.g. -svc).
+
+ Scroll detection is skipped for windows with 'OpenOffice' in
+ their name.

+
+
+x11vnc 0.9.7 2009-03-31
+
+
+New in the 0.9.7 x11vnc release:
+
+ Basic support for building with VirtualGL's TurboVNC (an
+ enhanced TightVNC for fast LAN high framerate usage)
+ encoding and TightVNC modifications. More info:
+ http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc
+ and x11vnc/misc/turbovnc/README.
+
+ The -ncache_cr option has been fixed and so in -ncache mode
+ smooth opaque window motions are now work correctly. Try
+ it out to see how smooth it is even on a slow link.
+
+ Support for Linux text consoles (virtual terminals, e.g. 1-6)
+ is provided via, e.g., 'x11vnc -rawfb vt2' (for virtual
+ terminal #2).
+
+ This is like LinuxVNC (i.e. text only), it avoids using
+ /dev/fb and uses /dev/vcsaN instead (the '-rawfb console'
+ mode uses /dev/fb.) With /dev/vcsaN the text terminal
+ is accessible even it if is not the currently active one.
+
+ The -rawfb option now supports framebuffers with bits per pixel
+ less than 8 (e.g. 4 or 1 bpp.)
+
+ Reverse connections now work in Anonymous Diffie Hellman SSL/TLS
+ mode. Reverse connections also work for VeNCrypt and
+ ANONTLS modes.
+
+
+ miscellaneous new features and changes:
+
+ The included SSL enabled UltraVNC java viewer now has a
+ configurable [Home] entry in the drives drop down menu.
+
+ In the -create, -svc, etc. modes one can now specify a
+ range of X displays to ignore in X11VNC_SKIP_DISPLAY.
+ Improvements and bugfixes were made to the find_display
+ and create_display scripts. FD_EXTRA option is provided.
+
+ The '-rawfb video' option finds the video device file more
+ carefully.
+
+ The -rmflag option allows a new way to indicate to other
+ applications that x11vnc has started.
+
+ All of the java applet parameters are now documented in
+ the classes/ssl/README file.
+
+ There is now a "sendbell" remote control command.
+
+ A one-time -padgeom once:WxH mode is added.
+
+ Improvements to the CUPS Terminal Services helper mode.
+
+ If the X display cannot be opened normally then the env. var.
+ XAUTHLOCALHOSTNAME=localhost is tried.
+
+ Bugfix for selection transfer to a now non-existent X window
+ (Thunderbird can cause this.) Related, the env. variable
+ LIBXCB_ALLOW_SLOPPY_LOCK is now set by default.
+
+ Bugfix for -8to24 mode due to nonstandard indexed color support.
+
+ The libvncserver and x11vnc autoconf/automake settings have
+ been improved.
+
+ libXrandr include file is now found on Solaris.

+-----------------------------------------------------------------------------
+
+
+x11vnc 0.9.6 2008-12-10
+
+
+New in the 0.9.6 x11vnc release:
+
+ x11vnc's SSL encryption is extended to support the VeNCrypt and
+ TLS (older; vino) SSL/TLS security type extensions to VNC.
+
+ Anonymous Diffie-Hellman key exchange (-ssl ANON) and Certificate
+ Revocation List support (-sslCRL) is added to the SSL
+ encryption mode.
+
+ The Java viewer applet can now be served up through the VNC port
+ (5900) in addition to the normal HTTP port (5800) via
+ the -http_oneport option. Previously this only worked
+ for SSL connections and HTTPS.
+
+ The "-rfbport PROMPT" mode presents a simple gui for the user
+ to select a port for the x11vnc service and a few other
+ settings. This enables a menu entry for naive users
+ that is included in x11vnc.desktop.
+
+ If x11vnc is not built with the Avahi Zeroconf library an external
+ helper program (avahi-publish or dns-sd on Mac OS X)
+ is used instead.
+
+ miscellaneous new features and changes:
+
+ The default mode for '-ssl' is now the '-ssl SAVE' mode; i.e.
+ the generated certificate is saved and reused in
+ subsequent sessions rather than being discarded.
+ Use '-ssl TMP' recover the old way. This change made
+ to for it to be more likely that the VNC Viewer can save
+ the accepted cert for future authentications.
+
+ The solid background color option works on the Mac OS X console.
+
+ The -reopen option enables x11vnc to try to re connect to the X
+ display if GDM (or other display manager) kills it just
+ after the user logs in.
+
+ The -dhparams option can be used to point to your own Diffie
+ Hellman parameters.
+
+ The -setdefer option allows tuning how quickly updates will
+ be sent. Default setting tuned.
+
+ The option -zeroconf is now an alias for -avahi/-mdns.
+
+ In pipeinput mode, the pipe filehandle is now closed when
+ x11vnc exits.
+
+ The -sshonly option turns off VeNCrypt and TLSVNC (vino) mod
+ leaving only the standard SSL (i.e. vncs://)
+
+ For testing, the option -rand in an alias for -rawfb rand -nopw
+
+ Minor tweaks to improve CUPS Print tunneling.

+
+
+x11vnc 0.9.5 2008-10-24
+
+
+New in the 0.9.5 x11vnc release:
+
+ Symmetric key encryption using the RC4, AES, Blowfish, and 3DES
+ ciphers is supported via the -enc cipher:keyfile option.
+ The SSVNC unix viewer 1.0.20 and later supports these
+ encryption methods.
+
+ Server-side scaling can now have different scale factors along
+ the horizontal and vertical axes. E.g. -scale 1280x1024
+ (same as -geometry 1280x1024) or -scale 0.8x0.75
+
+ The -chatwindow option allows a chat window to appear on the
+ X console during UltraVNC chats (requires the SSVNC
+ viewer package.)
+
+ miscellaneous new features and changes:
+
+ The HTTP Java viewer applet jar, classes/VncViewer.jar, has
+ been updated with an improved implementation based on
+ the code used by the classes/ssl applets.
+
+ A description and instructions are now printed out when
+ X_ShmAttach fails if one tries to attach to a remote
+ $DISPLAY (i.e. $DISPLAY is on a different machine from
+ the machine x11vnc is running on; this often happens
+ with SSH X redirection, X terminal servers, etc).
+
+ The -allow option now works correctly in -ssl mode.
+
+ The -remap option now works on the MacOSX console.

+x11vnc 0.9.4 2008-09-17
+
+
+New in the 0.9.4 x11vnc release:
+
+ Reverse VNC connections (-connect and -connect_or_exit options)
+ work in the -find and -create X session FINDCREATEDISPLAY
+ modes.
+
+ Reverse VNC connections (either normal or using SSL) can use a
+ Web Proxy, a SOCKS proxy, the UltraVNC repeater proxy,
+ an SSH connection, or even a CGI URL to make the outgoing
+ connection (-proxy option). Forward connections can
+ use the -ssh option to set up a reachable redirection.
+
+ Support for the ZYWRLE encoding is added, this is the RealVNC ZRLE
+ encoding extended to do motion video and photo regions
+ more efficiently by way of a Wavelet based transformation.
+
+ The session finding and creating modes (-find and -create) have
+ been improved to be more reliable and also provide a new
+ desktop types (xfce) and new service redirection options.
+
+ Support for indexed colormaps (PseudoColor) with depths other
+ than 8 is provided (depths 1 to 16 now work).
+
+ Java viewer applet source code is provided in the x11vnc 0.9.4
+ tarball so now everything can be built from source.
+
+ miscellaneous new features and changes:
+
+ To unset Caps_Lock, Num_Lock and raise all keys in the X server
+ use -clear_all, or by remote control 'x11vnc -R clear_all'
+
+ The -autoport option gives more control over the server port
+ range that probes.
+
+ The -ping option can be used to help keep idle connections alive.
+
+ The -finddpy and -listdpy utilities help to debug and configure
+ the -find, -create, and -display WAIT:... modes.
+
+ Some automatic detection of screen resizes are handled even if
+ the -xrandr option is not supplied.
+
+ The -advertise_truecolor option can workaround some VNC viewer
+ incompatibilities with PseudoColor.
+
+ The option '-clip xinerama0' can be used to clip to the first
+ Xinerama sub-screen, etc.
+
+ If a fast framebuffer read rate is detected the -wait and -defer
+ parameters are reduced to 10 and 15 msec, respectively.
+
+ Pasting of the selection/clipboard into remote applications
+ (e.g. Java) is improved.
+
+ Usage with dvorak keyboards is improved. The option -macuskbd is
+ available on MacOSX to use the original US keyboard code.
+
+ Via a compiler option (-DENABLE_GRABLOCAL) one can use the
+ -grablocal n option to filter VNC client input if someone
+ at the console has done mouse or keyboard input n secs ago.
+
+ The -sleepin option can now sleep a random amount of time between
+ min and max time delays (-sleepin min-max).

+x11vnc 0.9.3 2007-10-04
+
+
+New in the 0.9.3 x11vnc release:
+
+ This release provides client-side caching to improve interactive
+ response. Almost no VNC viewers implement caching which is why
+ VNC is slow compared to other remote graphics protocols.
+
+ The x11vnc caching will work with any VNC viewer, but they will
+ not hide the pixmap cache region that is below the main desktop
+ (one must adjust the window manually). The SSVNC Unix VNC viewer,
+ however, automatically detects and hides the region.
+
+ To enable caching, supply "-ncache n" to x11vnc, where the
+ number n, e.g. 10, indicates how much memory to devote to the
+ caching scheme.
+
+ See http://www.karlrunge.com/x11vnc/#faq-client-caching

+x11vnc 0.9.2 2007-06-18
+
+
+New in the 0.9.2 x11vnc release:
+
+ A compile-time bug is fixed for when the OpenSSL library is not
+ available or --without-ssl is supplied; previously the
+ build would fail.
+
+ One can configure x11vnc via "configure --with-system-libvncserver"
+ to use a system installed libvncserver library instead of
+ the one bundled in the release tarball.
+
+ If UltraVNC file transfer or chat is detected, then VNC clients
+ are "pinged" more often to prevent these side channels
+ from becoming serviced too infrequently.
+
+ In -unixpw mode in the username and password dialog no text will
+ be echoed if the first character sent is "Escape". This
+ enables a convenience feature in SSVNC to send the username
+ and password automatically.
+
+ miscellaneous new features and changes:
+
+ When building from the CVS tree --with-x11vnc must be supplied if
+ you want x11vnc to be built. The LibVNCServer release
+ tarball no longer contains the x11vnc source.

+
+
+x11vnc 0.9.1 2007-05-24
+
+
+New in the 0.9.1 x11vnc release:
+
+ A new Unix username identification scheme is provided when
+ SSL client certificates are used to authenticate VNC
+ viewers. The username is extracted from the 'Subject'
+ section of the cert. The option is "-users sslpeer="
+ which, like "-users unixpw=" already does, will cause
+ a switch to the Unix user. This is useful for the
+ -find and -create options that try to find an existing
+ X session associated with the user or create a new one.
+
+ The UltraVNC Java Viewer has been modified to support SSL
+ connections. Some bugs were also fixed and some
+ improvements added. A patch file and a compiled jar file
+ (UltraViewerSSL.jar and SignedUltraViewerSSL.jar in the
+ classes/ssl directory) are provided in the x11vnc package.
+
+ For the -user option groups are now handled better by using
+ initgroups(3), or if finer control is needed one can
+ use: "-users user1.group1,..."
+
+ When SSL client certification is being used and external login
+ programs are being used the env. var. RFB_SSL_CLIENT_CERT
+ is set to the clients certificate. Set X11VNC_SSLPEER_CN
+ to use the Common Name instead of the certificate email
+ address to find the unix username.
+
+ miscellaneous new features and changes:
+
+ The -wait and -defer defaults were lowered from 30 to 20
+ milliseconds, set the values explicitly if this increases
+ the load too much for your liking.
+
+ In -create mode where a Xvfb session is started, mwm was added
+ as a session type. setpgrp(2) is used for the spawned
+ process if available. The XKEYBOARD extension is
+ enabled (+kb, but it doesn't seem to always work).
+ TrueColor is forced to be the default visual (recent
+ Xvfb seem to choose DirectColor, this is likely a bug)
+ One can also force creating a new Xvfb by setting the
+ env. var. X11VNC_FINDDISPLAY_ALWAYS_FAILS (not exactly
+ clear what this would be used for).
+
+ The WAITBG env. var. enables -display WAIT:... to take place in
+ the background.
+
+ One can specify the X11VNC_SKIP_DISPLAY env. var. for a list of
+ displays to exclude in the FINDDISPLAY action. This can
+ also be specified via nd=... as a -unixpw login option.
+
+ setsid() or setpgrp() is called for the external command spawned
+ by the -gone option (since it may be long lived, e.g. a
+ screen locker).
+
+ The script "onetimekey" utility is provided in the classes/ssl
+ subdirectory that allows a (very long) string representing
+ a Client SSL certificate to be provided by the authenticating
+ client, or via https cgi script (e.g. after a web login).
+
+ Some bugs were fixed in the libvncserver implementation of
+ UltraVNC file transfer.

+
+x11vnc 0.9 2007-04-18
+
+
+New in the 0.9 x11vnc release:
+
+ VNC Service advertising via mDNS / ZeroConf / BonJour with the
+ Avahi client library. Enable via "-avahi".
+
+ Implementations of UltraVNC's TextChat, SingleWindow, and
+ ServerInput extensions (requires ultravnc viewer or ssvnc
+ Unix viewer). They toggle the selection of a single window
+ (-id), and disable (friendly) user input and viewing
+ (monitor blank) at the VNC server.
+
+ Short aliases "-find", "-create", "-svc", and "-xdmsvc" for
+ commonly used FINDCREATEDISPLAY usage modes (to find
+ the user's display or create one, etc).
+
+ Reverse VNC connections (viewer listening) now work in SSL
+ (-ssl) mode.
+
+ miscellaneous new features and changes:
+
+ New options to control the Monitor power state and keyboard/mouse
+ grabbing: -forcedpms, -clientdpms, -noserverdpms,
+ and -grabalways.
+
+ A simple way to emulate inetd(8) to some degree via the "-loopbg"
+ option.
+
+ Monitor the accuracy of XDAMAGE and apply "-noxdamage" if it is
+ not working well. OpenGL applications like like beryl and
+ MythTv have been shown to make XDAMAGE not work properly.
+
+ For Java SSL connections involving a router/firewall port
+ redirection, an option -httpsredir to spare the user
+ from needing to include PORT=NNN in the browser URL.
+
+ A -sleepin n option to delay startup by n seconds to let redirs
+ and listening clients to get started.
+
+ TightVNC file transfer is now off by default; enable via
+ -tightfilexfer

+
+x11vnc 0.8.4 2007-02-01
+
+
+New in the 0.8.4 x11vnc release:
+
+ Native Mac OS X Aqua/Quartz support. It exports the full
+ display (no X11 server, etc).
+
+ This provides an alternative to OSXvnc; some activities
+ are faster (and see the client-side caching feature
+ -ncache in the 0.8.5 development version for more
+ speedups).
+
+ x11vnc can act as a VNC reflector/repeater using the
+ "-reflect host:N" option. This is useful for large
+ classroom broadcasting or demos. You set up a number
+ of reflectors to spread the network and CPU load around
+ for better response.
+
+ A new login mode: "-display WAIT:cmd=FINDCREATEDISPLAY -unixpw ..."
+ that will Create a new X session (Xvfb, Xdummy, or
+ Xorg) for the user if it cannot find the user's X
+ session display via the FINDDISPLAY method. It will
+ be re-found upon reconnection.
+
+ This enables a simple "terminal services" mode based on
+ Unix username and password and where the user does not
+ have to memorize their VNC display number, etc.
+
+
+ miscellaneous new features and changes:
+
+ Option -nodpms to avoid problems with programs like KDE's
+ kdesktop_lock that keep restarting the screen saver
+ every few seconds even with active VNC clients connected.
+
+ The "-N" option couples the VNC Display number to the X Display
+ number. E.g. if your X DISPLAY is :2 then the VNC display
+ will be :2 (i.e. using port 5902). If that port is taken
+ x11vnc will exit.
+
+ Wireframe copyrect detection for local user activity (e.g. someone
+ sitting at the physical display moving windows). You
+ can disable this with the -nowireframelocal option.
+
+ To automatically fix the common mouse motion problem on XINERAMA
+ (multi-headed) displays, the -xwarppointer option is
+ enabled by default when XINERAMA is active. You can
+ disable this with the -noxwarppointer option.
+
+ By default in -reflect mode -shared is implied (it makes sense),
+ use -noshared after the -reflect option to disable this.
+
+ The -prog option lets you specify the full path (argv[0]) to
+ the program, in case it is spawned by inetd/tcpd and
+ cannot determine its path. The path is needed for the
+ -http option to guess the http classes directory.
+
+ Usually not needed, but there are many options for tuning the
+ native Mac OS X mode: -macnodim -macnosleep -macnosaver
+ -macnowait -macwheel -macnoswap -macnoresize -maciconanim
+ -macmenu.
+
+ An option -debug_xdamage has been added for debugging and profiling.

+
+
+x11vnc 0.8.3 2006-11-13
+
+
+New in the 0.8.3 x11vnc release:
+
+ The -ssl option provides SSL encryption and authentication
+ natively via the www.openssl.org library. One can use
+ from a simple self-signed certificate server certificate
+ up to full CA and client certificate authentication schemes.
+
+ The -sslverify option allows for authenticating VNC clients via
+ their certificates in either -ssl or -stunnel modes.
+
+ Certificate creation and management tools are provide in the
+ -sslGenCert, -sslGenCA, and related options.
+
+ An SSL enabled Java applet VNC Viewer applet is provided in
+ classes/ssl/VncViewer.jar.
+
+ The applet may also be loaded into the web
+ browser via HTTPS, i.e one can use the VNC port,
+ e.g. https://host:5900/
+
+ See our "Enhanced TightVNC Viewer" project, for native
+ SSL enabled viewers.
+
+ The -unixpw option supports Unix username and password
+ authentication. The -ssl or -localhost and -stunnel
+ options (or detection of an SSH tunnel) are enforced in
+ this mode to prevent password sniffing.
+
+ Coupling -unixpw with -display WAIT:cmd=FINDDISPLAY provides a
+ way to allow a user to login with their UNIX password
+ and have their display connected to automatically.
+
+ Hooks are provided in the -unixpw_cmd and "-passwdfile cmd:,custom:..."
+ options to allow you to supply your own authentication
+ and password lookup programs (e.g. LDAP).
+
+ The "-ultrafilexfer" alias is provided and improved UltraVNC
+ filetransfer rates have been achieved.
+
+ The -rotate option enables you to rotate or reflect the screen
+ before exporting via VNC. This is intended for use on
+ handhelds and other devices where the rotation orientation
+ is not "natural".
+
+ miscellaneous new features and changes:
+
+ Similar to -ssl, the -stunnel option starts up a SSL tunnel server
+ stunnel (that must be installed separately on the system)
+ to allow only encrypted SSL connections from the network.
+
+ Option -sslnofail to exit immediately if there are any SSL
+ connection failures.
+
+ A simpler variant of -unixpw is the -unixpw_nis option that
+ works in environments where the encrypted passwords are
+ readable, e.g. NIS.
+
+ x11vnc can be configured and built to not depend on X11 libraries
+ "./configure --without-x" for -rawfb only operation
+ (e.g. embedded linux console devices).
+
+ Add -cursor_drag to change the mouse cursor during Drag and Drop, etc.
+
+ Under the "-connect_or_exit host" option x11vnc will exit
+ immediately unless the reverse connection to host
+ succeeds. The "-rfbport 0" option disables TCP listening
+ for connections (useful for this mode).
+
+ The "-rawfb rand" and "-rawfb none" options are useful for
+ testing automation scripts, etc., without requiring a
+ full desktop.
+
+ Reduced spewing of information at startup, use "-verbose" (also
+ "-v") to turn it back on for debugging.

+
+x11vnc 0.8.2 2006-07-13
+
+
+New in the 0.8.2 x11vnc release:
+
+ Support for full mouse and keyboard input into the Linux
+ console framebuffer /dev/fb0 in -rawfb mode
+ (i.e. non-X11) by using the Linux "uinput" driver.
+
+ This enables, for example, viewing and interacting
+ with Qt-embedded/Qtopia-Core apps on Linux-based
+ handhelds, etc.
+
+ Options: -rawfb cons, -pipeinput UINPUT More info:
+ http://www.karlrunge.com/x11vnc/#faq-qt-embedded
+
+ Extension of the display option: -display WAIT:<disp-or-cmd>
+ to delay x11vnc's opening of the X display
+ until a VNC client connects (useful built-in:
+ -display WAIT:cmd=FINDDISPLAY, to find a user's
+ display and Xauthority data).
+
+ Options -grabkbd and -grabptr have x11vnc try to grab
+ the X display when VNC clients are connected to
+ prevent a (non-malicious) user at the physical X
+ display from performing keyboard or mouse input.
+ E.g. remote help-desk support.
+
+
+ miscellaneous new features and changes:
+
+ -allowedcmds option to fine-tune which external commands
+ may be run by x11vnc, rather than shutting
+ them all off with -nocmds.
+
+ -env VAR=VALUE convenience option to avoid the need of
+ setting environment variables before starting
+ x11vnc.
+
+ -allinput option to enable libvncserver handleEventsEagerly
+ parameter (not clear it yields an improvement).
+
+ -rawfb rand fun/testing option using /dev/urandom as a fb.
+
+ -license, -copying, -warranty option.

+x11vnc 0.8.1 2006-06-03
+
+New in the 0.8.1 x11vnc release:
+
+ Improved support for webcams and tv tuners with video4linux
+ /dev/video: see the "-rawfb video" and "-pipeinput VID"
+ options. (the latter gives a simple keyboard control
+ of a tv tuner; see also the -freqtab option for stations).
+
+ FBPM support for hardware that provides framebuffer power
+ management (it needs to be disabled when vnc clients
+ are connected).
+
+ The -usepw option will require x11vnc to use a password of
+ some sort or otherwise exit immediately. Put it in
+ your ~/.x11vncrc so you don't forget.
+
+ The command "x11vnc -storepasswd" will prompt for a password
+ without echoing and save it in ~/.vnc/passwd
+
+ The X CLIPBOARD selection is managed in addition to the
+ X PRIMARY selection.
+
+
+ miscellaneous new features and changes:
+
+ Convenience option for accessing the Linux console: -rawfb cons
+ etc. (requires /dev/fb0 to be working).
+
+ clipboard/cut-text input can now be managed on a per-client
+ basis.
+
+ -capslock and -skip_lockkeys options can help make CapsLock work
+ better.
+
+ The Xdummy wrapper script is included in the source tree.
+
+ A mode "-gone popup" as been added.
+
+ -24to32 option to avoid 24bpp problems.

+x11vnc 0.8 2006-02-13
+
+
+New in the 0.8 x11vnc release:
+
+ TightVNC file transfer support is enabled via the extension to
+ LibVNCServer added by Rohit Kumar.
+
+ The -passwdfile option has been enhanced to handle any number
+ of full-access and view only passwords in an easy to
+ maintain format, and additional features.
+
+ The -8to24 option enables multi-depth viewing on systems that do
+ not support -overlay. The 8bpp regions are transformed
+ to depth 24 TrueColor before exporting via VNC.
+
+ The x11vnc source code has gone through a major reorganization.
+ The build has been enhanced and many bugs fixed.
+
+
+ miscellaneous new features and changes:
+
+ -afteraccept option is like -accept however it enables running
+ a user supplied command after client authentication
+ has taken place. The RFB_* environment variables have
+ been extended.
+ -loop option will run x11vnc in an outer loop restarting each time
+ (useful for situations where the X server restarts often).
+ -slow_fb allows for slow polling for special purpose applications
+ (e.g. video). -blackout noptr,WxH+X+Y,... will prevent
+ the pointer from going into a blacked out region.

+
+
+x11vnc 0.7.2 2005-07-11
+
+
+New in the 0.7.2 x11vnc release:
+
+ The X DAMAGE extension is supported to dramatically reduce
+ resource consumption when idle: often 20 times less;
+ and to pick up small changed regions more quickly.
+
+ DAMAGE sends events indicating damaged (modified) screen
+ rectangles to x11vnc. These are used as hints to focus
+ the polling and also if the rectangle is below a size
+ threshold it is accepted unconditionally (i.e. dragged in
+ from the framebuffer). Tuning is possible with -xd_area.
+
+ DAMAGE is available on recent Xorg servers and Solaris 10.
+
+ -wireframe: Heuristics are used to guess when a window is being
+ moved or resized and during this period show only a
+ moving wireframe outline. Just like on video cards in
+ the 90's, remember? This is to avoid window "lurching"
+ when you move or resize one opaquely.
+
+ Also, -wirecopyrect applies the VNC CopyRect encoding
+ for the moved window. Both are on by default, use
+ -nowireframe or -nowirecopyrect to disable (aka -nowf
+ and -nowcr).
+
+ -scrollcopyrect: Sniff the X11 protocol via the RECORD extension
+ and to try to detect window scrolls (e.g. via scrollbar,
+ Up/Down arrow, etc). When detected, the VNC CopyRect
+ encoding is applied to the scrolled regions for a speedup.
+
+ The contents of the scrolling window may only be
+ approximate while it is being scrolled: e.g. tearing,
+ bunching-up, etc. The heuristics will also miss scrolls
+ by certain toolkits or applications, so those will still
+ happen the slow way. To disable use -noscrollcopyrect
+ (aka -noscr). Tuning is also available, see the -help
+ entry.
+
+ -listen: Makes x11vnc listen only on a single network interface.
+ -localhost now implies '-listen localhost'.
+
+ -rawfb: Instead of polling an X server framebuffer, poll a raw
+ one (i.e. a mapped file or a shm segment). E.g. for
+ the linux framebuffer device:
+
+ -rawfb map:/dev/fb0@1024x768x32
+
+ This is a bit out of x11vnc's scope but may have some
+ interesting applications. Perhaps /dev/video?
+
+ -pipeinput: Pipe the VNC user's pointer and keyboard input events
+ to a helper program you provide. Two examples are in
+ misc/vcinject.pl and misc/slide.pl. Primarily intended
+ for use with -rawfb to somehow kludge-up user input,
+ but it can also be used by itself.
+
+ Improvements for the magnification scaling case (e.g. -scale 2)
+ for use in low vision applications. It is faster and
+ no-blending :nb now works correctly.
+
+ More safety measures are taken WRT remote-control in the
+ default mode. See the -unsafe, -safer, -privremote,
+ and -nocmds options.
+
+ The GUI has been improved, and running with the options "-gui icon"
+ presents a small, simple gui instead of the full blown one,
+ and "-gui tray" attempts to embed the small icon in the
+ system tray. Use "-gui tray=setpass" to prompt for
+ session password creation at startup.
+
+
+ miscellaneous new features and changes:
+
+ -xkb: a simple test is performed at startup to see if it is a
+ good idea to apply -xkb mode for the current keyboard
+ keymapping (i.e. if keysyms like !, @, [ are otherwise
+ unavailable). To disable use -noxkb.
+ ISO_Level3_Shift vs. Mode_switch: Set things up in -xkb mode to
+ prefer ISO_Level3_Shift over Mode_switch for modtweaking.
+ No override; let me know if this causes problems.
+ -add_keysyms is now the default, use -noadd_keysyms to disable.
+ the added keysyms are periodically deleted.
+ -remap DEAD: shorthand for mapping many "dead" keysyms to their
+ "un-dead" counterparts, e.g. grave -> dead_grave. For
+ some VNC viewers that are unable to send the dead keysym.
+ -skip_dups: skip impossible duplicate key events sent by some VNC
+ viewers. -noskip_dups to disable (currently off by default).
+ -sloppy_keys: try to handle sloppy keyboarding (esp. between
+ different language keyboards) where, say, Shift is released
+ before the key.
+ -norepeat N: ping-pong N times if something else on the desktop
+ restores key autorepeating (e.g. session startup). Default
+ 2. Also, If the VNC client is idle for 5 min. autorepeat
+ is restored.
+ -wait_ui: If there is very recent user input, cut the -wait sleep
+ time by the specified factor (default 2.0).
+ -nowait_bog: Detection is now in place to watch for polling "bogging
+ down" (e.g. lots of scrolling text from a long build in a
+ terminal) and to sleep more. Use -nowait_bog to disable.
+ -flag: write PORT=5900 to a flag file to aid wrapper scripts.
+ -http: try to guess what the -httpdir should be and if found
+ enable http listening.
+ -clip WxH+X+Y: only show the specified rectangle not the
+ entire screen.
+ cursors are now scaled by default under -scale, use -scale_cursor
+ to modify this behavior.
+ -arrow n: select from some different arrow cursors (ignored under
+ XFIXES cursor grabbing mode).
+ -nolookup: disable DNS lookups for broken environments.
+ -seldir: fine tune and debug selection transfer.
+ build-time customization macros: SHARED, FOREVER, NOREPEAT,
+ REMOTE_CONTROL, SMALL_FOOTPRINT, default passwd, etc.
+ see the top of the x11vnc.c for more info.
+ -xtrap: DEC-XTRAP extension is supported for legacy systems
+ with insufficient XTEST extension (X11R5).
+ -shiftcmap: for legacy systems with non-standard colormap values.
+ -noxrecord: do not use the RECORD extension for anything (currently
+ only -scrollcopyrect and grabserver watching use it).
+ -grab_buster: fork a helper thread to watch for XGrabServer deadlock
+ in x11vnc and break the grab. Under -scrollcopyrect there
+ is a small window where x11vnc is vulnerable to this deadlock.
+ -dbg: A "crash shell" with tips on debugging will be presented
+ instead of exiting when a fatal error occurs.
+ -fixscreen: periodically refresh the screen to get rid of painting
+ errors, etc. induced by new features, jpeg compression, etc.
+ -speeds: Tell x11vnc what the network and fb speeds are instead of
+ having it try to measure them. (these speeds are used by
+ various features, such as -wireframe, -scrollcopyrect, etc.).
+ -wmdt: set the window manager or desktop to spare x11vnc from guessing.
+ -readtimeout: set libvncserver's read timeout parameter, useful on
+ very slow links that take more than 20secs to paint
+ the whole screen.
+ -nopw: If you use x11vnc without a password it now prints out a
+ scary warning message. Use -nopw to disable the warning.
+ plugged X event leaks; periodically purge any remaining buildup.

+x11vnc 0.7.1 2005-02-24
+
+
+New in the 0.7.1 x11vnc release:
+
+ Improved algorithm for approximating XFIXES cursors with
+ transparency (alpha channel). No more ugly black fuzz
+ around translucent cursors. Tuning parameters -alpha*
+ if it is still not right.
+
+ Added mechanisms to handle XFIXES cursors with transparency
+ exactly (i.e. blend in the background). Works by default
+ under -nocursorshape updates, and also works under limited
+ circumstances for cursorshape updates if the VNC viewer
+ is patched (TightVNC viewer patch provided).
+
+ -solid: to improve performance switch the background to a solid
+ color when clients are connected. Works on GNOME, KDE,
+ CDE, and classic X.
+
+ -input: allows fine-tuning the type of allowed user input
+ (Keystroke, Mouse-motion, Button-click). Useful for
+ certain applications of x11vnc, e.g. demos. Also
+ per-client settings via -R input:xyz..
+
+ -users: enables switching to different users if started as root.
+ Please read the description for details.
+
+ -gui ez: less daunting GUI with fewer options via '-gui ez' or
+ "Misc -> simple-gui" once started.
+
+ miscellaneous new features and changes:
+
+ -nap is now the default, use -nonap to disable.
+ -snapfb: snapshot h/w fb to RAM periodically, not clear how useful...
+ -timeout n: for use in certain applications, exit if no client
+ connects after n seconds.
+ -oa and -logappend for appending to logfiles.
+ -opts will just show the options w/o the long -help descriptions.
+ if you forget to set -display, it will beep and try :0 after a bit.

+x11vnc 0.7 2004-12-23
+
+
+New in the 0.7 x11vnc release:
+
+ Support for the XFIXES X extension to show the exact mouse cursor
+ shape. Requires libXfixes. For approximate cursor
+ shapes also see: -cursor (none|arrow|X|some|most)
+
+ -remote/-R: remote-control support: nearly every setting can be
+ changed dynamically without restarting x11vnc. For
+ example, "x11vnc -R shared", and "x11vnc -R scale:3/4"
+ will connect to a running x11vnc server to make it shared
+ and re-scaled, respectively.
+
+ -gui: launches a simple tcl/tk GUI based on the remote control
+ function. Requires the tcl/tk "wish" program.
+
+ -overlay: support for overlay/multi-depth (e.g. 24+8) visuals
+ on Solaris (SUN_OVL extension) and IRIX.
+
+ -xrandr: support for the XRANDR (X Resize, Rotate and Reflection)
+ extension: if the screen changes size or rotates x11vnc
+ creates a new framebuffer to match it. Useful to have a VNC
+ Viewer that supports NewFBSize extension. (also -padgeom)
+
+ -pointer_mode: Experimental pointer input handling schemes,
+ e.g.: "-pointer_mode 3" (similar to -nodragging)
+
+ man page x11vnc.1 and README files created.
+
+ miscellaneous new features and changes:
+
+ -sb: set screen blank idle timeout
+ -nocursorshape: disable cursor shape VNC extension.
+ RFB_MODE = "accept" or "gone" passed to -accept/-gone commands.
+ -vncconnect is now the default.
+ -norepeat is now the default.
+ "-id pick" to pick a window via xwininfo for the -id option.
+ -sid option: like -id but crops root window instead.
+ Related to remote-control: -query, -noremote, -sync,
+ -deny_all, -safer, -unsafe.

+x11vnc 0.6.2 2004-08-02
+
+New in the 0.6.2 x11vnc release:
+
+ -scale option for server side scaling (e.g. -scale 2/3).
+
+ -storepasswd option to create VNC password files.
+
+ ~/.x11vncrc simple config file support.
+
+ -cursorpos now the default (send cursor position updates to clients
+ that understand them, disable with -nocursorpos)
+
+ more connection info sent to the -accept and -gone commands.
+
+ new keyboard related features:
+
+ -modtweak is now the default (it automatically adjusts the modifier
+ keys state to send a Keysym properly, disable -nomodtweak)
+ this works around "ghost" keys like "< >" in XFree86.
+
+ -xkb option to use XKEYBOARD extension for modtweak-ing to further
+ improve the accuracy of sending Keysyms between different
+ language keyboards.
+
+ -skip_keycodes and -add_keysyms options to fine tune stubborn
+ keyboard differences.
+
+ -norepeat option to turn off X server key autorepeat when clients
+ are connected (works around the repeated characters problem)
+
+ -clear_mods and -clear_keys to send key release events at
+ startup and exit.
+
+ removed options:
+
+ -hints/-nohints: we now always use hints.
