#1973 new defect

mplayer disables DPMS timeouts, which creates problems when using as screensaver (e.g., electricsheep)

Description

When mplayer is running, DPMS timeouts do not ever trigger even though

xset q

shows that DPMS is enabled and timeouts are set. This causes a problem with the popular "electricsheep" screensaver that uses mplayer to play its AVI's. Connected monitors never turn off.

[ this problem also occurs with ffplay of ffmpeg ]

Issuing:

xset dpms force off

after mplayer has started causes the monitors to turn off (suspend and standby modes lead to monitors coming back on immediately afterward). So it's possible to run a script in parallel to electricsheep to force monitors off at regular intervals, but that's not ideal.

Is there a way to force mplayer to NOT disable DPMS timeouts? If not, there should be.

I did not author this patch. It was posted by Reimar Döffinger to the mplayer-dev-eng mailing list.

Reimar Döffinger provided a patch that fixes this problem on the mplayer-dev-eng mailing list. I've attached the simple one-line patch.

After applying the patch, mplayer -nostop-xscreensaver provides the desired behavior.
