KDE Screensaver stops working after mplayer


I noticed that after I view a video file with MPlayer, the KDE screensaver stops working as well as my monitor will not suspend.

and, no I am not using mplayer -stop-xscreensaver (or whatever the switch is).

I have seen some threads with this on google, but those are referring to older bugs in kde-2.x and early 3.0 version. and mplayer wasnt even mentioned. I ran a ps aux and checked to see if mplayer was still running, and no it isnt.

So, I thought that i'd post to this forum and see if anyone has seen a fix for this.


Thanks

Kubuntu 5.10
MPlayer 1.0pre7try2-3.4.5 (compiled from source)
KDE-3.4.3 (Ubuntu package)
X Window System Version 6.8.2 (Ubuntu 6.8.2-77)

Ancient thread, but I was searching on the same problem and it turned this up. In case it helps anybody, I had been running

Code:
#!/bin/sh
/usr/bin/xset -display ":0.0" s 900 +dpms
every ten minutes from cron before I'd identified today that mplayer was the problem (and, indeed, there may still be other broken apps that do similar things). Now that I've identified mplayer, I was going to just write a wrapper script that ran mplayer and then restored my settings, or just give vlc a try or something.

The only diagnostics are that when I *do* run mplayer with the -stop-xscreensaver switch (or the un(der)documented -nostop-xscreensaver switch or conf setting), I get

Code:
xscreensaver_disable: Could not find XScreenSaver window.
which seems to indicate the switch only applies to the separate xscreensaver program and mplayer unconditionally borks X's own screen blanking/DPMS as a separate thing.

BTW, this happens both on Slackware and Debian (in addition to Gentoo) so it's not distro-specific.

A second BTW is that, of course, for a general use workaround, you'd want to establish what the right display was and what the settings actually were and then restore them and so on.

A proper fix would still be welcome, of course.

-- Edit: oh, and I should say that it's not particularly a KDE problem, since I'm not using that.

I have noticed this problem for a long time. I use slackware and have had the same problem with fluxbox, xfce, and kde. I switched to xine for a while and didn't have the problem but I was experiencing lockups while watching videos with xine. This problem has been around so long I would have thought mplayer devs would have fixed it by now.
