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
Keyboard Control:
  auto repeat:  on    key click percent:  0    LED mask:  00000002
  XKB indicators:
    00: Caps Lock:   off    01: Num Lock:    on     02: Scroll Lock: off
    03: Compose:     off    04: Kana:        off    05: Sleep:       off
    06: Suspend:     off    07: Mute:        off    08: Misc:        off
    09: Mail:        off    10: Charging:    off    11: Shift Lock:  off
    12: Group 2:     off    13: Mouse Keys:  off
  auto repeat delay:  500    repeat rate:  20
  auto repeating keys:  00ffffffdffffbbf
  bell percent:  50    bell pitch:  400    bell duration:  100

DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 3600
  DPMS is Disabled
xset has been forcing a blank screensaver to activate every 600 secs (10 minutes).

Fixing it requires a simple terminal command:
xset s off
