Comment 3 for bug 728101

I can confirm this is happening to me as well on Asus U35F-X1, core i3. I start the music player, close the lid, and 10 minutes later when I open it back up the desktop is frozen but I can still move the mouse cursor. I cannot switch between applications that are already open. I can switch to console mode with Ctrl+Alt+F1 and issue sudo restart gdm. In power settings I have the screen set to blank when the lid is closed. I am running the Ubuntu Classic desktop 64 bit.
