[Bug 419328] Re: attaching external monitor: laptop display shows corrupted desktop

[Bryce Harrington]

Hi j, you mention that this bug occurs "using the latest Karmic" but
that's a bit ambiguous - could you report if you have been using karmic
and this regressed after a recent update, or if you've just upgraded
from jaunty to karmic and are now seeing the problem, or if this is a
first time install and you are just noticing the error now?

Please also run the command 'apport-collect 419328', which will attach
some additional information which may be useful in analyzing the bug.

>From what you've described, and your stack trace, this appears to be an
X freeze bug.  We have a recipe for debugging these issues.  Please
follow the directions on this guide to collect a Batchbuffer Dump:


https://wiki.ubuntu.com/X/Troubleshooting/Freeze#How%20to%20Get%20a%20Batchbuffer%20Dump%20%28-intel%20only%29

Also, the 2.8.1 driver was released last night, which allegedly contains
fixes for some freeze bugs.  We should have that available in Karmic
within the next few days, so that would be worth testing as well.  If it
still occurs there in 2.8.1, then we can forward this bug upstream at
that point.
