I have an issue which could be a bug, but before reporting it, I want to make sure I'm not doing something wrong.
When watching a movie with VLC on fullscreen, approximately in 10 minutes the screen goes blank. This happens despite having the "Inhibit the power management daemon during playback" option checked. This even happens when I go to the Ubuntu's system settings > Brightness and Lock and set the "Turn screen off when inactive for: " to "Never". (actually, no matter what value I set it to, the screen always goes blank after 10 minutes or so).
The only way I managed to disable the screen blanking is using the command line utility xset: xset -dpms
and xset s off
(it's possible only one of these is necessary).
Now, one thing that could possibly cause this is that I removed both gnome-screensaver and xscreensaver packages, because I'm not using screensaver. I only use the power-management to blank the screen (I assume it's different thing than screensaver, but I might be wrong). When no VLC us running, the screen blanking works normally even without those packages. That is, the screen goes blank after whatever timeout I set in the Brightness and Lock settings. Only when VLC is playng (and possibly only when in fullscreen), this issue occurs.
So my question is: Is this a bug in VLC (or elsewhere in Ubuntu), or should I install back gnome-screensaver
and/or xscreensaver
to make it work correctly again?
I have Ubuntu 12.04.
