[Launchpad Bug Tracker <802584@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I have configured screen saver to activate after 15 min. of inactivity
and power down screen of the laptop after 25 min. So well, almost always
the laptop has activated the screen saver or even the screen is black
after a long period of inactivity, when I press a key or move the mouse,
a window prompting my pass pops and then kwin crashes. Most of the
times, the window announcing the crash emerges (I didn't use to submit
the bug report cause I don't have installed the dbg packages due to
insufficient disk space in my /usr partition) and kwin is rerun and I
can work with my laptop. But another times, the screen remains black or
graphics begin to do weird things (windows partially deleted, desktops
blinking, etc.). When the screen remains black, I switch to a console
(CTRL+ALT+F1) kill the kwin process and when I return back to X (ALT+F7)
there is no more black screen (I have my desktop) but there is no window
manager, so I have to reboot in order to be able to work with my laptop.
This is annoying! Firstly, I thought the bus was in kcometen4, the
screen saver I used, but I changed to GLMatrix and problems remain (only
slightly better).

By the way, I think that the problems I have with laptop suspension and
hibernation are related to this bug, because sometimes, when I wake the
laptop up after an hibernation or a suspension I got a black screen
(after the window prompting my pass pops up) or a crazy X desktop or
directly a kwin crash.

Please, let me know if I could be of help in some way. Thanks a lot for
your work!!!
