Ubuntu/Linux force monitor to turn on/off

DPMS (Display Power Management Signalling) for vesa compliant devices can be controlled by two tools on linux:
  1. xset
  2. vbetool
man xset/vbetool for more details.

To force the monitor to stay turned on or off can be achieved by doing the following:

root@kubuntu:/home/babil# xset dpms force on/off
root@kubuntu:/home/babil# vbetool dpms on/off
