Do you have a backtrace? If so, please paste it. Though, I'm slightly confused: you say kwin crashes *and* eats CPU, but if it's crashed, then it can't use CPU, since the process has been killed. Do you get a crash dialog? Thanks for your answer. I don't have a backtrace, but if it can help to solve the problem and someone explains me how to get one, it would be appreciated :) Well, when any program stops working and consumes 100% of CPU I always say "it is crashed". May be it's not the correct way of naming it so I will explain it with more detail to avoid confusion: -When I press "ALT+TAB" my keyboard stops working. I can move the mouse and see the cursor moving around the screen, but it has no effects no matther where I click. I don't get a crash dialog. -If I connect to my machine via SSH (it takes a lot of time but finally I can login). The system works slowly and when run 'top' I can see the Kwin process using 100% CPU. -If I run 'killall -9 kwin' my keyboard and mouse in the KDE enviourment start working again and all KDE programs seem to work again too (except the fact that there is no windows decorations because I've killed Kwin ;-) ). If there is anything else I can do to help the problem to be solved just tell me. Regards. To get a backtrace, you can use "kill -SEGV <pid-of-kwin>", I think - that should cause a KDE crash handler to appear, with a backtrace tab. I've tried it, but nothing happens (just what I commented in my last post, my keyboard and mouse in the KDE enviourment start working again). I don't see any output after running "kill -SEGV `pidof kwin`" and I don't see any window on the KDE sceen. I've installed kdebugdialog but it is not showed either. Whay package/program should I install to get the "KDE crash handler"? Could you reproduce the bug? I see it remais as UNCONFIRMED :/ I've tried it at my brother's computer (Suse) and seems the bug is there too. I still can't reproduce this behaviour - you might want to try to find other users (in some KDE forum or IRC channel) who can reproduce the bug, to get more data points. They can then add a comment to this bug. I reproduced the bug two times . The keyboard and the mouse hangs. I have to do a hard reset to my computer. Note : The opcion "Show window list while switching windows" I have it disabled. Philip, I'm afraid I made a mistake when I reported the bug. To reproduce it, the option "Show window list while switching windows" must be disabled, sorry. |
