+\title Qt/Embedded environment variables
+
+\table
+\header \i Variable \i Notes
+
+\row
+\i QWS_SW_CURSOR
+\i If defined, always use a software mouse cursor even when using an
+accelerated driver that supports a hardware cursor
+
+\row
+\i QWS_DISPLAY
+\i Defines the display type and framebuffer, e.g.
+\c{Voodoo3 Mach64:/dev/fb1}
+Defaults to an unaccelerated Linux framebuffer driver on \c /dev/fb0.
+Valid drivers are QVfb, VGA16, LinuxFb (unaccelerated Linux framebuffer),
+Mach64 (accelerated for ATI Mach64 cards such as the Rage Pro),
+Voodoo3 (accelerated for the 3dfx Voodoo 3, should also work on Voodoo
+Banshee), Matrox (should work on all Matrox graphics cards since the
+Matrox Millennium), Transformed (for rotated displays), SVGALIB and
+VNC. Transformed displays have a special format: within the
+specification should be a multiple of 90 degrees rotation specified as
+Rot\<x\>, for instance Transformed:Rot90.
+
+\row
+\i QTDIR
+\i If defined this tells Qt/Embedded to where to find its fonts:
+fontdir should be in \c $QTDIR/etc/fonts/. If undefined it's assumed
+to be \c /usr/local/qt-embedded
+
+\row
+\i QWS_SIZE
+\i If defined forces Qt/Embedded into a window of \<width\> x
+\<height\> size centred within the screen, e.g. 320x200
+
+\row
+\i QWS_NOMTRR
+\i If defined, don't use Memory Type Range Registers to define the framebuffer
+as write-combined on x86. Write-combining speeds up graphics output.
+
+\row
+\i QWS_CARD_SLOT
+\i Tells the accelerated drivers which card to attempt to accelerate.
+This should be a path in \c /proc/bus/pci. It defaults to
+\c /proc/bus/pci/01/00.0 - the first device on the second PCI bus in the
+system, which is normally the AGP card.
+
+\row
+\i QWS_USB_KEYBOARD
+\i If defined, instead of opening \c /dev/tty open the USB low-level
+event device defined in QWS_USB_KEYBOARD (e.g. \c /dev/input/event0):
+this is useful if you wish to run X and Qt/Embedded side by side on
+different framebuffers.
+
+\row
+\i QWS_MOUSE_PROTO
+\i Defined as \<type\>:\<device\>, e.g. \c{Microsoft:/dev/ttyS0}. If you want to
+use a USB mouse directly (separate from X) use \c{MouseMan:/dev/input/mouse0}
+or similar. Valid mouse protocls are Auto (automatically sense protocol),
+MouseMan, IntelliMouse, Microsoft, QVfbMouse (only useful with QVfb)
+and TPanel, a sample touch panel driver.
+
+\row
+\i QWS_KEYBOARD
+\i Defines the keyboard type. Multiple keyboards can be handled at once,
+input will be read from all of them. Valid values:
+Buttons (an iPaq button device if QT_QWS_IPAQ is compiled, otherwise
+one for the Cassiopeia), QVfbKeyboard (only useful with QVfb),
+and TTY (either a USB keyboard or \c /dev/tty depending if QWS_USB_KEYBOARD
+is defined)
