Comment 29 for bug 762918

A couple of minutes ago, my computer with the screen-saver disable was with the screen turn off, but it received an update notification during the time when the screen was turn off and it freeze, also a few days ago the screen was turn off and I was listening music, and I press a key to go to the next song and it also freeze.
In both cases, I can move the mouse but when I tried to click an application using Unity of Ubuntu Classic it does not work, also, I can press Ctrl + Alt F1 and write top to see what it's happening but everything seen normal.
I upgraded from Ubuntu (64)10.10 to 11.04.
Thanks for helping us with this issue.
