Bug Description

Binary package hint: gnome-screensaver

Noticed recently (but often) on Dell XPS M1330 (Intel graphics), looks like a regression :

- When system has gone to screensaver, then screen turned off, moving mouse brings back a screen on which screensaver is static (stopped), mouse cursor moving OK, but no password dialog, no way to get out of this.

- Shitfing back and forth to text console and X11 works, text console works OK.

- The screensaver view gives the impression something works and it "would want to get out of this" : Seems to react to typing password blindly (disk activity, mouse cursor changes shape) but the screensaver static image stays there forever.

There's absolutely no way to get out of this except for rebooting the system completely. (restart gdm isn't enough)

I've found a potential fix:

-Install Compiz Settings Manager: sudo apt-get install compizconfig-settings-manager

-Go to OpenGL plug-in & uncheck the Sync to VBlank option.

I am trying a the moment wether this may work or not :) but it seems that it has worked for others. I forgot to mention in my previous comment that i was having this problem in Gnome desktop not Unity. For more about this fix check these links:
