Description Sami Farin 2015-12-10 21:24:22 UTC

Description of problem:

I was watching movie with mplayer, and I paused it while doing some other stuff.
I have in mplayer
  heartbeat-cmd="mate-screensaver-command -d"

Then, suddenly, mate session gets killed.

Comment 1 Wolfgang Ulbrich 2015-12-12 18:30:23 UTC

Hmm, i do not see that "mate-screensaver-command -d" execute in a terminal kill mate-session.
Does this works for you not using the command in mplayer config?

Comment 2 Sami Farin 2015-12-12 19:07:10 UTC

Do you have other ideas about what happened?
Mate does not crash if I have that command in config IF mplayer is not paused for a long time.  

Well, I try again.

Comment 3 Wolfgang Ulbrich 2015-12-30 18:33:14 UTC

You didn't understand what i wanted to know.
Does "mate-screensaver-command -d" execute in a terminal kill mate-session in your box?

Comment 4 Sami Farin 2015-12-30 19:44:16 UTC

Nope.  

I got another crash, I was watching movie in mplayer and session crashed when I pressed enter for next movie.  

org.mate.panel.applet.WnckletFactory[10145]: wnck-applet: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.

oh yay, I had in .xsession-errors.old the following. (the same time as above, file timestamp 22:30:26.204787638 )
web.whatsapp.com has enabled notifications in Chrome.

In xfce4 I don't get warnings about whatsapp.

It is not helpful if you don't answer my question!
How should i help you?
Please do not spam this report with another issue!
Please open a new one.

Comment 6 Sami Farin 2015-12-30 19:57:28 UTC

I answered, answer was "Nope.", now I am thinking whatsapp is causing the crash.

Comment 7 Wolfgang Ulbrich 2015-12-30 19:58:40 UTC

Ok, i didn't saw this answer.

So it looks like that mplayer caused the issue when using this command.

> I got another crash, I was watching movie in mplayer and session crashed when I pressed enter for next movie.

Honestly, this is a problem with mplayer.
I suggest to open a report against mplayer.

Comment 8 Sami Farin 2015-12-30 20:04:36 UTC

Honestly, what about that whatsapp thing?

Comment 9 Wolfgang Ulbrich 2015-12-30 20:10:07 UTC

I don't know 'whatsapp' and this is not a fedora package.
Btw. i use gnome-mplayer from rpmfusion which supports mate-screensaver out of box ;)
