I have an issue where most often my screensaver will not activate and it's somewhat hard to determine what's preventing it. Is there a way that I can view whatever processes are asking the OS not to display the screensaver?

I'm on Linux Mint 11.

I guess your mouse is doing tiny movements. It`s been a while, but I experienced this strange behaviour with a mouse that was reacting to sunlight.

So try to remove your mouse...

Did that, that didn't help. – Naftuli Tzvi Kay Oct 4 '11 at 3:32
I am out of ideas here. I once tried to research some things about DPMS and did not come up with much information. – Nils Oct 4 '11 at 20:47

I simply went to Screensaver Preferences:

Made sure that Activate screensaver when computer is idle was checked.

Then, I ran killall gnome-screensaver, then restarted the screensaver with gnome-screensaver. Voila, it worked. How/why, I'm not sure.

As far as having the output shut off, this isn't working yet, but I think it's because I have a weird setup (laptop lid shut, output to two monitors over HDMI and VGA).

Also: I had to prop open my laptop lid in order to get the monitors to shut off as per the setting in "Power Management." – Naftuli Tzvi Kay Nov 28 '11 at 20:16
