According to https://wiki.ubuntu.com/Bugs/FindRightPackage the gnome-power-manager package is most likely to cause the bug.

Status changed to 'Confirmed' because the bug affects multiple users.

This issue has gone away for me. Same for everyone else?

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.

The attachment "Patch fixing blue screen bug for mutter" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
