Bug Description

I have configured ubuntu to turn of screen after 10 minutes of inactivity. When I wake up computer the external primary screen is light blue and the laptop-screen is black and displaying my usename at the top right corner.

I use Ubuntu 12.04 with propitary Nvidia drivers. I also use GDM and gnome-shell (Gnome 3). I use a external monitor as primary screen and laptop-screen as secondary. Both resolution is 1920x1200. Laptop is Dell XPS M1530.

Hi,

I'm affected by this bug, but only when using cinnamon, not unity. Something was done in compiz to prevent this problem but this was not done in muffin/mutter.

I've found out that when using xscreensaver the issue happens as well, BUT when moving the mouse xscreensaver's password prompt shows up (with black background), and then goes away and blue comes back when the timeout expires, that sounds like some X buffer is turning blue, and xscreensaver is successful in overwriting it, while gnome-screensaver isn't.

I had the same issue with 12.04 and nvidea drivers. I even downloaded the Gnome Live image to report it as upstream bug. I think there was a bug in gnome-screensaver. But now after installing 12.10 the bug disappeared.

The bug is in mutter and muffin (which is a fork of mutter).

The upstream bug where it was finally fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=677116

I'm attaching here the patch that fixes the problem for mutter.

affects: gnome-power-manager (Ubuntu) → mutter (Ubuntu)
