Is there a better command to use to determine whether it's running or
not? What about --version or something?
We really shouldn't be running gnome-screensaver-command --poke every 30
seconds during playback if gnome-screensaver-command isn't running. As
a matter of fact, a lot of users with gnome-screensaver installed were
reporting issues with playback, and if the poke takes a long time when
the screensaver isn't running, I could see that causing some issues.
Any chance you could do a test for me and run:
time gnome-screensaver-command --version && echo $?
time gnome-screensaver-command --poke && echo $?
both with and without gnome-screensaver running.
I'm also hoping to write a new screensaver handler using
xdg-screensaver, but it would be a very different structure from the
current, so it's not a quick fix, and it's not that high on my TODO list
(since I don't run screensavers--after all, 95% of our population seems
to think that a desktop background is a screensaver, so how popular
could real screensavers be, anymore :).
