@Kai Jauch:
The 2.6.32-16 kernel has the 2.6.33 drm (graphics drivers) stack in it.
This was done for many varied reasons, one of which is better support
for intel graphics. If you are having issues now, I suggest opening a
new bug just to keep things separate and not get too tangled up with the

Although the fix hasn't reached upstream, I believe upstream is working
on solving the solution through further development work to make things
behave more correctly. In the meantime, we need a fix for Lucid, so
the patch was committed to the lucid kernel tree. Please test the next

Hi back, recently my kernel got upgraded so I lost the patch and when
I open the lid I have to do the VT switch trick.
But now I noticed that it does not always work, because sometimes when
I switch to the VT, Xorg crashes and I obtain a .crash report.
Should I attach it here, file a new bug, or
@Nicolò Chieffo:
FYI, the patch is taking a longer to get upstream than would be desired
as there's some question as to whether it is the best fix for this
issue.
I would assume at this point that X crashing is another symptom of this
bug. If X still crashes when a patch fix is in the kernel,
Ok, I will wait for a fix, then test again the Xorg problem.
In the mean time is there any possibility to disable screen blaking on
lid close?
Thanks!
