I am running Ubuntu GNOME 15.04 and I have install gnome-screensaver, however after doing some searches through my system, and my system settings, I am unable to find any configuration settings for this screensaver. And when I run it in Terminal I get:
** (gnome-screensaver:20082): WARNING **: screensaver already running in this session
So how do I configure it?
