Public bug reported:

I am running unity system compositor on my desktop in dual screen mode
with Intel HD 2500 graphics.

When I play video, even when it's halted and the media player window
(vlc and mplayer) is on another work place, the screen flickers black.

I was able to find the following messages in /var/log/Xorg.0.log:
[  8967.357] (II) Setting DPMS mode for output 1 to 0
[  8967.884] (II) Setting DPMS mode for output 3 to 0
[  8972.730] (II) Setting DPMS mode for output 1 to 0

Watching the file with tail -f gives one or two new lines of these
messages after each flicker.

I experience this only on my desktop in dual screen mode, not on my
laptop that also uses Intel graphics (HD 4000) and is currently running
saucy.
