After upgrading to 13.04 from Xubuntu 12.10, my monitor no longer goes to sleep automatically. In Power Manager, On AC, Monitor, I have it set to put the display to sleep after 10 minutes off after 15, but the monitor stays on the whole time. However, I can manually put the monitor in sleep mode by running xset dpms force off. Any ideas?

Edit: On further investigation, even if I use xset dpms force off, the monitor switches back on after a 10-15 seconds, but the screensaver does not go off.

Turn off / remove xscreensaver:

sudo aptitude remove xscreensaver

Thanks to maestrobwh1 on Ubuntu Forums for the answer.
