Hello.
I'm experiencing random freezing on Gnome 3, however, the cursor is moving.

Xorg log
Here, in the last line from what I see the AIGLX didn't get resumed (maybe it shouldn't)?
Code:

Those lines look suspicious to me from the message log

I had to kill pid #2144 which is /usr/bin/gnome-session to restart the gnome.

I'm running OpenSuse 12.3 on a laptop (Dell Inspiron 15).
