Bug#451571: EXA causes hangs on i845G
Hello,
I'm running Debian unstable on a Dell PC with 845G onboard graphics.
When using Gnome, recently X started locking up after switching virtual
desktop a few times. Before it locked up I noticed it was slower than usual.
After it hangs, the mouse pointer still moves and the Xorg process started
eating up all available CPU. I can still log in from remote and kill -9 it.
I then ran KDE instead, which solved the lockups, but the desktop remained
painfully slow.
After I finally found this bug report, I added this line to my "Device"
section in /etc/X11/xorg.conf:
Option "AccelMethod" "XAA"
and Bingo! Gnome no longer hangs after changing desktops and the desktop is
as fast as it used to be.
I'm running the latest xserver-xorg-video-intel version 2:2.2.0-1.
