Das „class“ Attribut lässt sich mittels

obxprop | grep "^_OB_APP"

bestimmen.

xrandr --output DVI-0 --auto --scale 2x2 --left-of DisplayPort-0 --output DVI-1 --auto --right-of DisplayPort-0 --output DisplayPort-0 --auto

Um das beim Autostart auch zu machen: .config/autostart/lxrandr-autostart.desktop

  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

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