Title:
Raring regression: SNA fails completely; UXA causes random hangs
Status in “xserver-xorg-video-intel” package in Ubuntu:
Expired
Bug description:
The following occurred after I updated from Quantal to Raring.
I have an i5 2500K Sandy Bridge. When I remove /etc/X11/xorg.conf and
login to lightdm, SNA is used, but this causes my second monitor to go
out of sync, and my first monitor stops updating (though the mouse
cursor works). I am forced to do Ctrl+Alt+F1 to reboot.
When I create the following xorg.conf:
Section "Device"
Identifier "intel"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
Everything works, but sometimes, Xorg locks up for a few seconds.
