Version: 2.0 (using Devel) Installed from: Compiled sources Compiler: g++ 4.2.3 OS: Linux when watching a DVD in full-screen mode, it is extremely annoying to have to move the mouse every X minutes because the screen goes blank.. if it's a normal window it could be ok.. but if you put it in fullscreen it's presumably because you want to sit far from your pc, so it would be nice to stay there and not move around.
Well this is a bug, because as far as I know it does disable the screensaver. What distro do you use?
Same here on Gentoo with recent version from trunk.
I have the same problem with debian packages KDE 4.2RC1.
Dragon Player does disable the screensaver - however this isn't the same as disabling the screen turning itself off through power saving, something we're not currently doing. I'm currently integrating calls to Power Devil so that should fix this soon.

I confirm this is an issue related to power management. On the same system, my screen turns off after 15-20 minutes while wtaching a film, but xine-ui doesn't. I suppose it does turn of energy screen saving properly. However, I don't seem to have been able to make Power Devil stop applying screen energy save, whatever the settings I tried though.

Have the same problem here with power saving. It is really annoying to get disturbed watching a movie every 15 minutes. Please fix this! As for now I'm sticking with mplayer.
Suspend inhibition has now been added to trunk. Intend to backport to 4.2.1. Display power saving is being investigated.
I can confirm this bug on Kubuntu 8.10 with the KDE 4.2 PPA packages from the repositories.
I've got the same issue, too: Kubuntu 9.04, KDE 4.2.2
*** Bug 190156 has been marked as a duplicate of this bug. ***
Confirmed on Mandriva 2009.1 - KDE 4.2.2
I can confirm this not for DVD, but when watching video files. Using kde4.3 beta1
Strange, I had the issue when looking a DVD, too.
Not strange, the problem is related to any video!
Yeah, but #14 said that the problem would occur only for video files, not for discs, which I can not confirm.
I haven't tried discs...only files
Same problem on OpenSUSE 11.1 with KDE 4.2 and KDE 4.3 RC 3. Only workaround is to set the energy profile to presentation, which IMHO dragonplayer should do automatically when going to fullscreen.

Other players in KDE 4 have this problem too (Kaffeine 0.8.x, VLC 0.9.x). This didn't exist in KDE 3. So the problem might not be DragonPlayer itself. Could it be the new Phonon? backend? I haven't tried Kaffeine 1.x series yet, it I believe uses Phonon at least.
Dragon Player uses KnotificationRestriction to disable the screensaver - it is not done by Phonon. It uses this method, which has an outstanding open bug: https://bugs.kde.org/show_bug.cgi?id=181585
Can you provide any ETA on fixing this? I do love KDE 4, it has many innovations and great feel. But lacking the support for watching movies is kinda lame. Manual workarounds seem to exist (presentation mode) but it is not the same. And a normal everyday regular user can't find the workarounds, such feature is supposed to work out-of-the-box! I'm sure many agrees that this should just work...
If other players have the same problem, then this most probably is an issue of powerdevil - and should therefore be reassigned. I guess the bug is that powerdevil turns off the screensaver but omits to make a change to the "display power management". So can anyone reassigne the bug? And yes, I agree that this should be fixed as soon as possible, especially given that the fix probably is rather simple.
I use VLC in Mandriva Cooker (2010 alpha). VLC allows now to see a whole DVD. Note: I made a dd copy of the dvd in mydvd.iso and VLC can read it. Dragon should be able to read it too..
This is probably coincidental, but might be related somehow. Richard Hughes writes about a similar problem with gnome power manager (http://blogs.gnome.org/hughsie/2009/07/30/accidental-blanking-and-gnome-power-manager/)
I can confirm what Pierre observed, on debian/testing, with vlc 0.9.9a and KDE 4.2.4, I don't have the problem anymore. (can't test with dragonplayer)
Occurring here on Arch Linux with KDE 4.3.0/Dragon Player 2.0

According to comment #21 other players have this issue too under KDE. So I guess a fix in Dragon player leaves that unchanged. Should there be another bug report filed concerning that?
If you look at Kaffeine 1.0-pre2 release notes, there is: * added screen saver inhibition (using DBUS; org.freedesktop.ScreenSaver) Source: http://kaffeine.kde.org/?q=node/25 I haven't tried it, so if somebody could check it out?
On a side note, I just watched a 2h movie with Kubuntu Karmic using VLC 1.0.1 and KDE 4.3 from the official repos both. And guess what? I never got screensaver nor power savings! And they worked after the movie was finished! Hooray!
