I just tried it and it works nicely for turning off the display from within X. However, when you enter S1 (via something like 'xset dpms force off && acpiconf -s 1'), the screen turns back on and changes to the system console. I'd think about putting this in an rc.suspend-like script, but given that it is an xset command, I doubt that would work. Or is there another way to do this that I am missing? -- Alan Gerber
