X.org configurationEdit

Edit

• /etc/X11/xorg.conf

Add the following

Section "Module"
	Load  "glx"
	Load  "extmod" #miscellaneous extensions module
	Load  "xtrap"
	Load  "record"
	Load  "dbe" # Double buffer extension
	Load  "dri" 
EndSection

Section "DRI"
	Mode	0660
EndSection


Section "Device"
	Driver      "radeon"
	
	Option "AccelMethod" "EXA"
	 # XAA/EXA
	Option "AccelDFS"    "1"
	 # 1/0 On for PCIE, off for AGP
	 # Manpage: Use  or  don't  use accelerated EXA DownloadFromScreen hook
	 # when possible.
	Option "GARTSize" "64"
	 # 0-64 Megabytes of gart (system) memory used.
	 # Wrongly defaults to 8MB sometimes, see your logfile.
	 # Bigger seems better.
	Option "EnablePageFlip" "1"
	 # 1/0 Increases 3D performance substantially
	 # seemingly in XAA mode only
	Option "ColorTiling" "1"
	 # 1/0 Increases 3D performance substantially
	 # affected stability only positively on my system
	Option "RenderAccel" "True"
	Option "Backingstore" "True"

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 extentions 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
