Hello,

since the update of the Xorg packages last week I see the problems with 
the graphics card in /var/log/messages (see below). Every now and then, 
the graphics output is delayed. From time to time, the screen gets 
distorted during login or the computer does not accept any keyboard or 
mouse input.

Is this a known problem?
