[Bug 698120] Re: Dual head corruption on 2.6.37 lucid backport

 

** 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.
