Some help needed, please! I can run X only with "vesa" driver @60Hz and my eyes are bleeding! This rather old computer (Compaq Deskpro 233 Mhz) has also eaten Windows98Se and 3Dfx Voodoo1 card so I can play very old games S3 Trio64V2-DX/GX is connected to Voodoo and from voodoo signal goes to monitor. S3 has 2 MB of graphics memory. S3 and Voodoo are connected to PCI slots. Voodoo can't work alone, it needs S3. Windows works fine @85Hz, 1024*768 and 16 bit colors. So this won't work: # /etc/X11/xorg.conf (xorg X Window System server configuration file) Section "Device" Identifier "S3 Trio64V2-GX" Driver "s3" BusID "PCI:0:4:0" VideoRam 2048 Option "UseFBDev" "true" EndSection Section "Monitor" Identifier "PanaSync TX-D1753-G" Option "DPMS" HorizSync 30-81 VertRefresh 50-160 EndSection Section "Screen" Identifier "Default Screen" Device "S3 Trio64V2-GX" Monitor "PanaSync TX-D1753-G" DefaultDepth 16 SubSection "Display" Depth 1 Modes "1024x768@85" "800x600@85" "640x480" EndSubSection SubSection "Display" Depth 4 Modes "1024x768@85" "800x600@85" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1024x768@85" "800x600@85" "640x480" EndSubSection SubSection "Display" Depth 15 Modes "1024x768@85" "800x600@85" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1024x768@85" "800x600@85" "640x480@85" EndSubSection EndSection Section "ServerLayout" Identifier "Default Layout" Screen "Default Screen" InputDevice "Generic Keyboard" InputDevice "Configured Mouse" InputDevice "stylus" "SendCoreEvents" InputDevice "cursor" "SendCoreEvents" InputDevice "eraser" "SendCoreEvents" EndSection Section "DRI" Mode 0666 EndSection ... but if I change driver to vesa it works: Section "Device" Identifier "S3 Trio64V2-GX" Driver "vesa" BusID "PCI:0:4:0" EndSection Section "Monitor" Identifier "Generic Monitor" Option "DPMS" HorizSync 30-86 VertRefresh 50-160 EndSection Section "Screen" Identifier "Default Screen" Device "S3 Trio64V2-GX" Monitor "Generic Monitor" DefaultDepth 16 SubSection "Display" Depth 1 Modes "1024x768" "800x600" "720x400" "640x480" EndSubSection SubSection "Display" Depth 4 Modes "1024x768" "800x600" "720x400" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1024x768" "800x600" "720x400" "640x480" EndSubSection SubSection "Display" Depth 15 Modes "1024x768" "800x600" "720x400" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1024x768" "800x600" "720x400" "640x480" EndSubSection SubSection "Display" Depth 24 Modes "800x600" "720x400" "640x480" EndSubSection EndSection in /var/log/kdm.log I found these two chapters: X Window System Version 7.0.0 Release Date: 21 December 2005 X Protocol Version 11, Revision 0, Release 7.0 Build Operating System:Linux 2.6.15.7 i686 Current Operating System: Linux ilzu-desktop 2.6.15-26-386 #1 PREEMPT Thu Aug 3 02:52:00 UTC 2006 i586 Build Date: 16 March 2006 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.
