Ubuntu 12.04 Desktop Freezing Randomly

ice2921 · 08-28-2013, 05:23 AM

Hello,

I am experiencing random desktop freezes. The only way I can gain access to my system again is by rebooting the computer. After looking at the system processes via an SSH session I was able to see that the Xorg process was running quite high, using lamost 100% of the CPU time. I am wondering if it has something to do with my hardware, my GPU drivers specifically. Hopefully the below information will help.

My system information is as follows:

Code:

12.04.2 LTS, Precise Pangolin
