I got that corrupted screen too on Natty Beta1 with intel video card

[José Dapena Paz (jdapena)]

I got hte same issue with the official natty drivers. But even also with xorg-edgers ppa.

Current packages here:
xserver-xorg-video-intel 2:2.15.0+git20110714.212fa986-0ubuntu0sarvatt~natty
linux-image-3.0.0-5

I'm using gnome-shell, but happens also on unity and metacity (non accelerated). The behavior degrades with time, but restarting desktop removes most of corruptions with exception of some images that may be cached and get corrupted.

With a specific xorg-edgers ppa version:
xserver-xorg-video-intel 2:2.15.0+git20110605.bdb396a4-0ubuntu0sarvatt~natty
and adding this configuration in xorg.conf:

Section "Device"
Identifier "Intel gpu"
Driver "intel"
Option "Shadow" "true"
Option "RelaxedFencing" "false"
EndSection

I got almost stable behavior even with gnome-shell. Corruption would happend far later, if any. But in recent packages even this configuration doesn't help (and the old package got removed from my apt cache, so I lost my "stable" configuration).

By the way, my hardware: Intel Core i5 2540m in a Dell Latitude E6320.

Status changed to 'Confirmed' because the bug affects multiple users.

[madbiologist (me-again)]

Is this still occurring on Ubuntu 12.04 "Precise Pangolin"?
