Description Bastien Nocera 2008-05-08 10:13:15 EDT

After starting a session, Xorg will be consuming ~20 to ~30% of the CPU, when
the X session is idle. Switching to using XAA as the acceleration method makes
the CPU usage drop to negligible levels. With EXA on, fullscreen windows take a
few seconds to redraw.

Attached is the sysprof output when running with EXA on.
