** Description changed: 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.
