After upgrading to oneiric, I experienced another problem. Everything works fine with an old flat monitor with res 1280x1024.
On a large monitor (1920x1200, IIyama) the screen is flickering/flashing. There was many messages in Xorg.0.log like that:
[ 24055.092] (WW) intel(0): Page flip failed: Device or resource busy
[ 24055.092] (WW) intel(0): flip queue failed: Device or resource busy
so I've disabled page flipping in /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
Option "TripleBuffer" "false"
EndSection
(following bug #850628)
Performance is a little bit affected but it works.
