KDE 4.5 Freezes frome time to time with a INTEL GM45, Why?

Hi people!

I don’t know why but since I upgraded the KDE 4.4 desktop from openSUSE 11.3 to 4.5, the desktop just freezes some times.

If i was listening music, or watching a video I can still hear everything and even move the mouse, but nothing works. :frowning:

So I switch to TTy1, perform a init 3, then init 5 to restart all the graphic system, and start again. This happens without message, without log, and without clue… :X

Should I downgrade to 4.4 or this has a Workaround?

Thanks in advance for all your help!

Where did you look when you say “no log”?

dmesg
/var/log/messages
/var/log/Xorg.0.log

Where else should I check ?
