Distribution SpecificEdit

This is for specific changes needed to be done for a specific distribution. Make sure to follow the general instructions as well

GentooEdit

  • Recompile kernel as described above
  • Edit: /etc/make.conf
    • Add USE flag
      • video_cards_radeon
    • Add VIDEO_CARDS variable
      • VIDEO_CARDS="vesa radeon"
        • its a good idea to always add vesa as a backup
  • Install programs
    • emerge mesa libdri xf86-video-ati
  • Recompile xorg-server
    • emerge—deep xorg-server
  • Update world, may not be necessary, but a good idea
    • emerge—update—deep—newuse world
  • Edit xorg.conf as described above
  • Reboot computer

DebugingEdit

Xorg crashesEdit

  • login as root
  • Execute: X -configure
  • Try the new config as root, as it will describe
  • Ctrl-Alt-Backspace to exit Xorg
  • compare new xorg.conf to old one and modify accordingly

General debuggingEdit

Benchmarking
  • Benchmarking and testing opengl
    • Execute: glxgears
      • Output on a Pentium D, 1G DDR2
        • 9002 frames in 5.0 seconds = 1800.346 FPS
    • GL O.B.S.
      • Output on a Pentium D, 1G DDR2
        • GL_pointz 1.0 : 470.2 FPS
        • GL_shadow 1.0 : 289.4 FPS
        • GL_blit 1.0 : 678.2 FPS
        • GL_blit_ext 1.0 : 676.2 FPS
        • GL_smoke 1.0 : 477.8 FPS
Check to see if DRI is enabled
  • Execute: glxinfo |grep direct
    • Output: direct rendering: Yes
Check what extensions are enabled in Xorg
  • xdpyinfo
    • It will show you if Composite, GLX, XFree86-DRI, etc is enabled
Check log files for problems
  • /var/log/Xorg.0.log
    and
  • Execute: dmesg
