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
