Hello,

I have Kubuntu 11.04 on my HP machine, there is a Core 2 Duo 2.00 GHz 
with a nVidia 9500 GT 1GB. I use the official nVidia driver which gives 
good performance for KWin and OpenGL.

Sometimes, when I resize a window, Xorg starts to burn up 100% of the 
CPU time and the computer is frozen. I can only access it via SSH and 
that is very slow.

I can `sudo killall -9 xorg`, but then I loose all my data. What can I 
do to recover from those freezes without loosing my data in open 
applications?

What log files can I post for you to be able to diagnose the problem 
better?


Regards,

Martin
