Dear Maintainer,
I am using mate window manager. Many a times when I'm viewing a video,
after sometime the window goes blank. I have to use the mouse and the
video comes back. I have no idea why it happens. As shared above, I
have a speculation that the screensaver might be kicking in but have
no idea if it's happening, why it's happening like that.

Looking forward for people to fix it or tell me what I need to do.

Seeing this on xfce too.

While the timing matches the screensaver, when I lower the screensaver
time and restart vlc it didn't happen. Seems intermittent so a pain to
debug.

To reproduce the issue we need more information. Which desktop
environment are you using? Do you use some very special custom config?
etc.

Cheers

Hi Sebastian,
Thank you for taking the time out and trying to get the bottom of
this. i'm using mate desktop and don't think I'm using any custom
config here.

It seems I have to use the mate power manager sleep inhibit applet but
even using that does not get it right. It seems there is some issue
with mate power manager inhibit applet itself which they are not able
to work it out (as of yet).

Looking forward to see if you can help in this matter.

I'm sorry, but I won't be able to help you here. This looks a lot like
mate-screensaver bug and needs to be addressed in mate upstream (see
the mentioned upstream issue). Once mate supports the required DBus
interfaces, this will just work.

Re-assigning to mate-screensaver.

Cheers

Hi Shirish, hi Sebastian,

The proposed DBus solution mentioned in the upstream bug report [1]
seems to be the correct approach here. This won't be fixable for
jessie anymore, though.

Greets,

I'm still seeing this on xfce with xscreensaver in sid - it's really
annoying. Most likely a vlc problem.

Hi Jonathan,

Nope, as discussed earlier [1], it is a problem related to not
implementing the XDG Inhibit/UnHibit interface in mate-screensaver and
obviously also in xscreensaver.

Probably also in xscreensaver then. Might make sense to clone this bug
(or file it anew against xscreensaver with enough background
information).
