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. diff --git a/hw/kdrive/vesa/vbe.c b/hw/kdrive/vesa/vbe.c deleted file mode 100644 index cedefe9fc..000000000 --- a/hw/kdrive/vesa/vbe.c +++ /dev/null @@ -1,706 +0,0 @@ -/* -Copyright (c) 2000 by Juliusz Chroboczek - -Permission is hereby granted, free of charge, to any person obtaining a copy -of this software and associated documentation files (the "Software"), to deal -in the Software without restriction, including without limitation the rights -to use, copy, modify, merge, publish, distribute, sublicense, and/or sell -copies of the Software, and to permit persons to whom the Software is -furnished to do so, subject to the following conditions: - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
