Description Pablo Dotro 2011-08-19 12:18:49 UTC

Application: kwin (4.7.00 (4.7.0))
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Trying to get back to the desktop after screensaver activation, or from sleep mode.
Kwin crashes and the bug reporter opens itself. This behavior happens every time. Looks like some compatibility problem with the intel video chips.
I am using the onboard video chipset (the board is an Intel DG931). 

- Unusual behavior I noticed:
The screen flickers, the panels on the desktop sometimes get "broken".

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Comment 5 Thomas Lübking 2011-10-20 17:47:20 UTC

We can so far not say for sure, but it's very likely that both bugs in the driver have the same source. The workaround from bug #252817 should still work.

In case, that's one more evidence for the relation, but in general please do
a) not post to bugs marked as duplicates
b) do not post different backtraces to existing (and in this case "closed" ie. duplicated) bugs. It's confusing at best and they'll be completely ignored at worst.
The crash in this backtrace is filed as #282376 - so this time there's no need to report it again - and it's still a driver bug ;-)
