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 [Current thread is 1 (Thread 0x7f70c8eb47a0 (LWP 1325))] Thread 3 (Thread 0x7f70aaa18700 (LWP 1346)): #0 0x00007f70c86f9143 in select () at ../sysdeps/unix/syscall-template.S:82 #1 0x00007f70c4ae032c in qt_safe_select (nfds=16, fdread=0x1c94790, fdwrite=0x1c94a28, fdexcept=0x1c94cc0, orig_timeout=<value optimized out>) at kernel/qcore_unix.cpp:82 #2 0x00007f70c4ae53d0 in QEventDispatcherUNIXPrivate::doSelect (this=0x1c945d0, flags=..., timeout=0x0) at kernel/qeventdispatcher_unix.cpp:219 #3 0x00007f70c4ae604a in QEventDispatcherUNIX::processEvents (this=0x1c93f20, flags=...) at kernel/qeventdispatcher_unix.cpp:919 #4 0x00007f70c4ab7882 in QEventLoop::processEvents (this=<value optimized out>, flags=...) at kernel/qeventloop.cpp:149 #5 0x00007f70c4ab7abc in QEventLoop::exec (this=0x7f70aaa17db0, flags=...) at kernel/qeventloop.cpp:201 #6 0x00007f70c49ce924 in QThread::exec (this=<value optimized out>) at thread/qthread.cpp:492 #7 0x00007f70c4a99c2f in QInotifyFileSystemWatcherEngine::run (this=0x1c681d0) at io/qfilesystemwatcher_inotify.cpp:248 #8 0x00007f70c49d1175 in QThreadPrivate::start (arg=0x1c681d0) at thread/qthread_unix.cpp:320 #9 0x00007f70bf0d1d8c in start_thread (arg=0x7f70aaa18700) at pthread_create.c:304 #10 0x00007f70c870104d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 #11 0x0000000000000000 in ??

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 ;-)
