Not sure if this belongs in settings or power manager. Description of problem: Screensaver does not start & does not lock screen. Power manager does kick in later and turns off the monitor, but the screen remains unlocked. Version-Release number of selected component (if applicable): xfce4-settings-4.8.2-2.el6.x86_64 xfce4-power-manager-1.0.10-1.el6.x86_64 How reproducible: always.
Is xscreensaver installed? Is it running?
gnome-screensaver was installed and running, xscreensaver wasn't (installing it now)
Sadly, you can't use newer gnome-screensaver with Xfce. They switched to using a gnome-session related ping to determine idle time, so it would never trigger under Xfce. ;(
Then there should probably be a dependency on xscreensaver somewhere... Anyway, I'm not getting much luck with xscreensaver either: dmaziuk@yellowtail:~$ ps -aef | grep screen dmaziuk 8168 8078 0 17:49 ? 00:00:00 xscreensaver -no-splash dmaziuk 8752 8749 0 17:57 pts/1 00:00:00 grep screen dmaziuk@yellowtail:~$ I had it set up to kick in after 2 minutes ("cosmos") and the screen was still unlocked 5 minutes later.
One more thing: the panel button worked before and fired up cosmos screensaver. Now it's starting xscreensaver with whatever its default selection happens to be -- so it seems the selection in settings widget works with gnome-screensaver, but not with xscreensaver.
OK, it appears the problem is that settings widget isn't actually doing anything. I used it set cosmos screen saver to kick in after 15 minutes. I then used xscreensaver-demo to choose an ant screensaver, kick in after 2 minutes, and lock screen after another minute. I came back 5 minutes later & I had ants crawling over my screen & it was locked.
Are you sure that gnome-screensaver is not running at all? Which exact settings widget are you using? can you find it via 'ps' ?
Aha. So clicking on Settings - Screensaver in the menu fires up gnome-screensaver-preferences. Going through Settings - Settings Manager - Screensaver does fire up xscreensaver-demo.
So, this is all solved now? Feel free to re-open if there's anything further needed.
