we need some way for gnome-screensaver to signal that it has finished fading,

With my hardware (ATI HD 3500), I get the black screen in Kubuntu with

One workaround is to use the User Switcher panel applet, instead of the
Indicator Applet Session. For some reason, the Indicator Applet Session
dims the display before switching; when you come back to that user's
session, you either get a dimmed screen (which you can fix with xgamma

I was able to further work around this issue by putting a script

Waiting on patch or way to force the above to occur automatically, but
seems this is a bug in xserver, so reassigning there for now.
I've added a release nomination since this feels to me like a type of
bug which could be acceptable for an SRU.

workaround from upstream bug: running xgamma -gamma 1.0 fixes the

so to ease the pain, go to System-Preferences-Keyboard shortcuts, and
