Comment 0 for bug 994306

I have upgraded to 12.04 two days ago and since then, the GUI has hung 4-5 times (a couple times a day basically). I'm running Gnome3 (not Unity)

Here is a forum post which describes what happened and what I have done:

http://askubuntu.com/questions/130803/12-04-gui-hangs

I don't use much, only Eclipse, Chrome and terminal windows. Skype and Pidgeon are running as well. The hangs have happened in the middle of using Eclipse or typing into a terminal window.

Prior to the upgrade (I was on 11.10) I had no similar problems.
