Comment 52 for bug 328232

hi all, i think i found the solution, at least for me, becose compiz.real use no more cpu, with integrated graphics, simply we have to edit xorg.conf , this is what we have to inject
  Section "Device"
          Identifier "Configured Video Device"
          Driver "intel"
          Option "AccelMethod" "EXA"
          Option "MigrationHeuristic" "greedy"
  EndSection

just edit the device's section to adapt it to this one
now, cpu usage is max 35 percent, and even less .
be sure to keep a bachup of your original xorg.conf.

i use ubuntu 9.04 jaunty
