Robert Hooker, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

Title:
Gamma values are not being set properly after a second fade out
resulting in a black screen

Bug description:
Binary package hint: gnome-screensaver
When running the test-fade app in gnome-screensaver the gamma values
are improperly being set after the second fade, resulting in a
permenant black screen until manual adjustment of the gamma values.
Steps to reproduce:
get the gnome-screensaver source and build it
cd /path/to/gnome-screensaver/src/
./test-fade
it will attempt to fade twice, after the first fade and restore the second
fade will not come back unless you manually fix the gamma values with a command
such as
xrandr --output LVDS1 --gamma 1:1:1
Here is a script to reproduce and automatically adjust fix the gamma
values afterwards so its usable with one machine, you have to manually
move the cursor or hit a key after each fade.
#!/bin/bash
./test-fade
sleep 10
xrandr --output LVDS1 --gamma 1:1:1
