please inform us, what does "xset dpms force off" do?  And for what 
circumstances/purpose do you use it?  I looked in the man-page of 'xset' 
and found it, but I wasn't sure enough to risk using it in case it did 
something I didn't know how to get out of*

*like blanking my screen (see "off" + mentioning suspending), or like 
turning on "DPMS Energy Star Features" (see man-page, "Setting these 
values implicitly enables the DPMS features."), or something. Please 
tell us :-) and did you mean
-it's a preventative measure to screen-glitches?
-it's a remedy for screen glitches after they happen?
-it's an alternative to suspending for the purpose of saving power?

sorry :0)
