Control: retitle -1 When a video is playing or paused, vlc execs "xdg-screensaver reset" every 30 seconds, flickering the screen

Thanks to strace, I've found the problem: vlc executes
"xdg-screensaver reset" every 30 seconds, which executes
"xset dpms force on", which flickers the screen.

Then, I wonder whether executing "xdg-screensaver reset" is the right
thing to do. "xdg-screensaver suspend ..." has the same problem, but
if I understand correctly, it can be done only at the beginning, so
that the problem becomes minor. Firefox and MPlayer don't have any
flickering problem, so that there may be something better.

Also, disabling the screensaver while is video is paused is incorrect,

The fact that xset flickers the screen may be another bug.
