After enabling, I did this: sudo xset dpms force off The LCD turned off. I moved the mouse, and it came back on. I've always used my laptops without DPMS, even though I sometimes leave it on over night. In those instances, the screen has blanked, but never turned off. I so far haven't experienced any problems, but then again, I'm not leaving it on over night as much as you probably are. Not sure what else to suggest since it worked for me. Maybe Xorg isn't configured properly? Good luck, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.14-1.1653_FC4 i686 GNU/Linux 15:11:38 up 8:11, 4 users, load average: 0.12, 0.19, 0.40
