-.TH Xvesa 1 __vendorversion__
-.SH NAME
-Xvesa \- VESA Bios Extensions tiny X server
-.SH SYNOPSIS
-.B Xvesa
-.RI [ :display ]
-.RI [ option ...]
-.SH DESCRIPTION
-.B Xvesa
-is a generic X server for Linux on the x86 platform.
-.B Xvesa
-doesn't know about any particular hardware, and sets the video mode by
-running the video BIOS in VM86 mode.
-.B Xvesa
-can use both standard VGA BIOS modes and any modes advertised by a
-VESA BIOS if available.
-
-.B Xvesa
-runs untrusted code with full privileges, and is therefore a fairly
-insecure X server.
-.B Run at your own risk.
-.SH OPTIONS
-In addition to the normal KDrive server's options (see Xkdrive(1)),
-.B Xvesa
-accepts the following command line switches:
-.TP 8
-.B -mode \fIn\fB
-specifies the VESA video mode to use. If mode
-.I n
-is not supported by your BIOS and hardware,
-.B Xvesa
-will fail, hang your system, damage your hardware, or cause a global
-thermonuclear war; you are on your own. This option overrides any
-.B -screen
-options.
-.TP 8
-.B -listmodes
-list all supported video modes. If
-.B -force
-was specified before
-.BR -listmodes ,
-lists all the modes that your BIOS claims to support, even those that
-the
-.B Xvesa
-server won't be able to use.
-.TP 8
-.B -force
-disable some sanity checks and use the specified mode even if the
-BIOS claims not to support it.
-.TP 8
-.B -shadow
-use a shadow framebuffer even if it is not strictly necessary. This
-may dramatically improve performance on some hardware.
-.TP 8
-.B -nolinear
-don't use a linear framebuffer even if one is available. You don't
-want to use this option.
-.TP 8
-.B -swaprgb
-pass RGB values in the order that works on broken BIOSes. Use this if
-the colours are wrong in PseudoColor and 16 colour modes.
-.TP 8
-.B -map-holes
-use a contiguous (hole-less) memory map. This fixes a segmentation
-violation with some rare BIOSes that violate the VESA specification,
-but may cause slightly higher memory usage on systems that overcommit
-memory.
-.TP 8
-.B -force-text
-ignore saved video mode and switch back to regular 25x80 text mode
-on server exit or VT switch.
-.TP 8
-.B -verbose
-emit diagnostic messages during BIOS initialization and teardown.
-.SH KEYBOARD
-Multiple key presses recognized directly by
-.B Xvesa
-are:
-.TP 8
-.B Ctrl+Alt+Backspace
-Immediately kill the server.
-.TP 8
-.B Ctrl+Alt+F1...F12
-Switch to virtual console 1 through 12.
-.SH BUGS
-.B Xvesa
-opens all IO ports and runs your VESA BIOS, which may be assumed to be
-buggy. Allowing your users to run
-.B Xvesa
-is probably a security hole.
-
-.B Xvesa
-records the current BIOS mode when it starts and restores that mode on
-termination; if the video card has been reprogrammed by another application,
-the display will almost certainly be trashed. The alternative of saving and
-restoring the complete video card state has proven unreliable on most video
-cards.
-.SH SEE ALSO
-X(__miscmansuffix__), Xserver(1), Xkdrive(1), xdm(1), xinit(1).
-.SH AUTHORS
-The VESA driver was written by Juliusz Chroboczek who didn't realise
-what he was doing until it was too late. Keith Packard then added
-support for standard VGA BIOS modes and is especially proud of 320x200
-16 colour mode.
