I am using xset dpms force off
to manually turn my screen off to save power.
However, it turns back on after some time (20 – 40 seconds).
Distro: Ubuntu-Lucid
Graphics: Intel 4500 MHD
Trying steps in this solution (Turning off screensaver or wireless) did not work. Can it be due to any other reasons like network (magic packet) or usb devices?

This seems to be a known bug and you can read more detail on launchpad as well as on ubuntuforums. The issue is that somehow
gnome-power-manager
and thexset
commands conflict with each other.The solution is to run
xset dpms force off
in a loop, a python script pretty much works for most of us.Give it a try, and see how it goes.
