Title:
[gm45] Dual head corruption on 2.6.37 lucid backport
Status in linux package in Ubuntu:
Invalid
Bug description:
Lenovo X301 laptop, 4G ram, Intel(R) Core(TM)2 Duo CPU U9400 @
1.40GHz. Intel GM45 Express graphic chipset, Kubuntu 10.4.1 LTS Lucid
32 bits, Xorg driver "intel"
# uname -a
Linux wall-e 2.6.37-12-generic-pae #26~lucid1-Ubuntu SMP Wed Jan 5 22:54:38
UTC 2011 i686 GNU/Linux
# version.log
Ubuntu 2.6.37-12.26~lucid1-generic-pae 2.6.37
Symptoms:
When starting X with the external screen attached to the VGA connector, I
can't type anything in the login/password at the kdm greeter dialog. I can
switch to VT1. Then I can kill kdm. Restarting kdm gives fatal error with
technical messages about gem.
Starting without the external screen is okay. If I plug the external
screen and start using it (xrandr), the cursor becomes corrupted when
it is inside a konsole window on the laptop screen, but gets back to
normal outside this window. Then X freezes after a while.
Working single-headed without plugging the external screen at all is
fine so far.
Previous versions 2.6.35 and 2.6.32 did not do this
Previous version 2.6.37-11 already had the problem.
