I am running openSuSE 11.3 on a Thinkpad T400 laptop (with Intel+ATI switchable graphics). I made a clean install of openSuSE 11.3 (earlier running 11.2), and updated to KDE 4.5.
Now my screen freezes frequently. I can move the mouse cursor all over the screen, but cannot start any application; the keyboard doesn’t work too. The only way for me to get things to work is to logout and login again.
