Stop Xubuntu From Turning of Your Monitor Every 10 minutes

There is this nasty little bug in Xubuntu 14.04 and 14.10 that turns on a blank screensaver every ten minutes regardless of your power or light locker settings.

You can check your xset settings to see if your system is suffering from the same problem.

In a terminal type:

xset -q

xset has been forcing a blank screensaver to activate every 600 secs (10 minutes).

Fixing it requires a simple terminal command:
xset s off
