Screensaver starts while playing a Video with Kaffeine (missing build-dependency on libxtst-dev)

the same thing happens to me. the strange thing is that it worked fine in 9.04 beta and RC.

Also happens with my 9.04 64bit setup.

Ditto for me on i386 (core 2 quad) Jaunty 9.04 final. Double ditto in that Intrepid, which I have just upgraded from, didn't do this.

Same problem for me as well on i386. Also a regression from Intrepid.

I have the same issue. I use Ubuntu 9.04 i386 32bits, and I have never had this problem with previous ubuntu versions

I'm not sure it's relevant, but it seems that vlc doesn't prevent the screensaver from launching either (although I'm not sure it's suposed to)

Same issue since Jaunty (not in Intrepid).

Still also present in Totem...

Same thing here... Kubuntu 9.04
This is a very annoying issue... thanks for the fix, still can't find one since May 1st...

I am experiencing the same issue described here since I upgraded to Jaunty (not in Intrepid).

I am using Kubuntu 9.04 and the Kaffeine installed version is 0.8.7-1ubuntu5.

I have also realised that DPMS power saving options are also not disabled while playing a video (that means, monitor will stand-by as if no action was going on when watching video). This was also working fine on Intrepid before upgrading.

Finally, I have the same issue if the video playback is done using Mplayer or Xine.

I can provide other necessary info (logs, traces) if requested to me.

Hi,

I forget: My Grafics Card is a Nvidia GeForce 8800GS runing with the original NVidia Driver from EnvyNG.

Is there anybody who has the same problem with an ATI, Intel or other vendors Grafics card?

Hi,

I also forgot to mention I am using 64bit version of Kubuntu 9.04.

My video card is also Nvidia (GeForce 7300) and I am using 'nvidia' driver; this is my xorg.conf, just in case:

This doesn't seems to happen with dragon player. Can someone else confirm ?

Yes the other Players i tried (VLC, Totem, ...) do it fine.

It's only with the Kaffeine Player.

Status in “kaffeine” source package in Ubuntu: New

Bug description:
Binary package hint: kaffeine

My Screensaver starts, when I watch a movie with Kaffeine in Ubuntu 9.04 64bit. I tried in fullscreen and windowed mode. it doesn't matter. It's new in Jaunty. In Intrepid (on yesterday) the screensaver doesn't start.

Same here, with gnome-screensaver. kaffeine should inhibit the screensaver when playing video. And it's definitly a regression.

On the other hand, when diffing intrepid's 0.8.6-2ubuntu2 and jaunty's 0.8.7-1ubuntu5 with debdiff and `filterdiff -x "*/Makefile.in" -x "*/configure" -x "*/aclocal.m4" -x "*/src/input/dvb/*"' I can't see what caused this regression. So it may be somewhere else in the stack.

Same issue here with Kubuntu 9.04 64Bit running XFCE4 and kaffeine, does not happen with vlc ...

Happens to me as well. In Intrepid everything was fine, Jaunty has this annoying behaviour.
I am experiencing this on two machines, on with an Ati and one with a nVidia graphics card.

I am thinking, it might have something to do with Power Devil, which was newly introduced and replaced kde-guidance-powermanager.
The problem is, that I can't tell PowerDevil to make an exception for Kaffeine, as guidance used to.

Same here. AMD Turion 64X2. Nvidia 7150. Kubuntu JJ.
worked fine in Hardy.
Could it be related to this old BUG: https://bugs.launchpad.net/ubuntu/+source/kaffeine/+bug/30018

After some testing with powerdevil turned off completely the screensaver still keeps cutting in, so my earlier assumption that it might be powerdevil is wrong.

Hello,

the same problem, first use of newly installed kaffeine in jaunty i386 system, nVidia, GeForce4 MX 440.

I've tried a little script to work around:

gconftool-2 --type boolean -s /apps/gnome-screensaver/idle_activation_enabled false
kaffeine %U
gconftool-2 --type boolean -s /apps/gnome-screensaver/idle_activation_enabled true

but it still failed.

I did some more testing. The Screensaver also kicks in if I use Gwenview's slideshow feature.
However, it does _not_ start if I use Okular in fullscreen (presentation) mode.
I hope this helps.

Cheers.

I can't replicate this problem, but I have occasional access to a computer that can. I think somehow two instances of gnome-screensaver are being run at once.

I've attached a script that attempts to work around the problem, and collects some debugging data at the same time. Could people try running the attached script for a day or two, then attaching /tmp/screensaver-bugs.txt to a comment in this bug report?

/tmp/screensaver-bugs.txt reports the current time, reports any running instances of gnome-screensaver, kaffeine and gwenview, and reports the login time (i.e. the modification time of the .Xauthority file). Presumably gnome-screensaver is either being run when you log in or when Kaffeine/Gwenview starts.

I'm using gnome and mplayer, and after upgrading to ubuntu 9.04, the screensaver starts when watching video. It didn't do that before the upgrade. Is it really only people using kde that have commented here before me? It would be a little strange that I'm the first gnome user reporting about this screensaver problem, it should have been noticed before I think?

No, I'm actually using GNOME too. Funny, I was thinking that the problem could be because I'm not running KDE :-)

Same here.

ps aux |grep screensaver

only shows one instance on the screensaver. I use two display (one for LCD and one for TVOUT).

Yeah, cancel my previous theory (two instances of the screensaver running at once). I've just had access to the computer again - the bug is still there and there's no sign of any second instance. It is possible to stop the screensaver by killing gnome-screensaver while Kaffeine runs, so I'm marking this a gnome-screensaver issue too.

Well, gnome-screensaver inhibition (through gnome-screensaver-command -i)
works as expected, so the odds are more likely in kaffeine's field.

Ciao,

I noticed there may be some bad interaction between gnome-screensaver and power managment. Indeed, my problem is that the screen turns off, rather than the screensaver starting. Disabling turn-off feature in power management seems to solve the issue. Maybe disabling the screensaver should disable turn-off feature too (and thus is a gnome bug)?

Regards

Hm, does inhibit (gnome-screensaver-command -i) also deactivate this
turn off feature? It's true that it only blanks the screen and not
lock it. Still it seems that the right hooks aren't called as it
works with vlc & co. just fine

Hmm, interesting. I had a quick poke around in the source for Kaffeine and Gwenview, which shows:

1) Gwenview uses completely different methods to disable the screensaver. Gobnuts, could you check whether Gwenview triggers the screensaver when the screensaver is disabled? If not, this is probably an unrelated bug, which should be filed against Gwenview

2) I also can't see any changes to the way Kaffeine handles the screensaver between 0.8.6 (in Intrepid) and 0.8.7 (in Jaunty).
   Search (case-insensitively) for 'xtest' in 'kaffeine/src/kaffeine.cpp' to see the screensaver-related bits

3) I can't work out how to get any better debugging information out of Kaffeine without recompiling it

4) If someone can work out how to make Kaffeine print kdDebug messages (perhaps with kdebugdialog?), or is willing to do some experimental recompilation, there are some possible causes we could investigate

5) Even if Kaffeine is the direct cause, it's not doing anything that should break Peter's gconftool-2 workaround, so I still think the gnome-screensaver guys should look into this

I'm running Kubuntu 9.04. I don't have gnome installed, I may have some libraries, but no gnome-screensaver. Nothing else seems to start up in parallel with kaffeine.

I did have the KDE screensaver kicking in, until I disabled it, but this doesn't stop the monitor from switching off in the middle of watching something.

My guess is that either an application is expected to disable the screensaver (which in turn is meant to disable the energy saving screen blanking), or it is meant to do both itself. If nothing has changed with Kaffeine, then perhaps the behaviour of X has changed? The way that an app is meant to notify X it is a video player, playing a video, may have changed- either a new method introduced, or an older method or quirk has been removed- that might explain why other video players are fine?

Seems I can replicate this after all, and it's a build dependency issue: a missing comma in debian/control caused libvorbis-dev and libxtst-dev not to be installed.

MOTU SRU?

The packages on https://edge.launchpad.net/%7Epkern/+archive/ppa/+sourcepub/652996/+listing-archive-extra should fix the issue. Testing would be appreciated. (It looks that it still activates the screensaver on kaffeine pause.)

Humm, seems to work fine for me, no more screensaver during DVB-T playing with your package :)
Thanks :)

Test package works for me.

The fix is non-applicable to karmic. (New packaging entirely since the app moved to KDE4)

@ Philipp: Your updated package fixed this for me, too.

Sorry for the long delay.

+kaffeine (0.8.7-1ubuntu6) jaunty; urgency=low

NACK; version number should preferably by 1ubuntu5.1, target should be jaunty-updates.

Whoops, I meant jaunty-proposed above.

This bug affects me too.
Although I noticed this behaviour first with the update to 9.10.
In 9.04 I didn´t noticed this bug. On my system it affects the VNC Player, Kaffeine, Dragon Player and Totem Player. So I suppose it would affect any player you will install. Power Management is disabled on my system so I can´t test this.

MOTU-SRU is waiting on a properly formatted debdiff (see comment #42/43). Please resubscribe motu-sru once this is available.

Thanks.

As pointed out in IRC, a re-ack from motu-sru for the minor changes above is pedantic; Consider this an ACK from motu-sru to continue with uploading a correctly versioned and targeted package.

Accepted kaffeine into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Anyone who can test the proposed package? If not, the proposed update will be removed again. Thanks!

Fix confirmed. After installing the version from jaunty-proposed, the screensaver will no longer start, while kaffeine is playing (when it stops playing, the screensaver will then start after the desired time).

This bug was fixed in the package kaffeine - 0.8.7-1ubuntu5.1

---------------
kaffeine (0.8.7-1ubuntu5.1) jaunty-proposed; urgency=low

  * Add a comma between libvorbis-dev and libxtst-dev to get the latter
    installed into the build chroot, thanks to Andrew Sayers. (LP: #365770)
