Das „class“ Attribut lässt sich mittels

Einstellungen speziell für ATI (Radeon) opensource X11 Treiber

Unter /usr/share/X11/xorg.conf.d/20-radeon.conf anlegen:

Section "Device"
  Identifier  "My Graphics Card"
  Option  "AGPMode"               "8"   #not used when KMS is on
  Option  "AGPFastWrite"          "off" #could cause instabilities enable it at your own risk
  Option  "SWcursor"              "off" #software cursor might be necessary on some rare occasions, hence set off by default
  Option  "EnablePageFlip"        "on"  #supported on all R/RV/RS4xx and older hardware and set off by default
  Option  "AccelMethod"           "EXA" #valid options are XAA and EXA. EXA is the newest acceleration method and it is the default.
  Option  "RenderAccel"           "on"  #enabled by default on all radeon hardware
  Option  "ColorTiling"           "on"  #enabled by default on RV300 and later radeon cards.
  Option  "EXAVSync"              "on"  #default is off, otherwise on
  Option  "EXAPixmaps"            "on"  #when on icreases 2D performance, but may also cause artifacts on some old cards
  Option  "AccelDFS"              "on"  #default is off, read the radeon manpage for more information
EndSection

Ganz wichtig: EXAVSync=on entfernt jedes image tearing und performance Problem, dass ich mit den „offiziellen“ Treibern hatte…
