Thanks for the info Sean. There is / was no entry in the xorg.conf indicating dpms or apm either. I added the dpms under the monitor 0 section. I'd already checked to see if the screensaver had dpms enabled and it was. Now if it does not work, I'll start thinking even more about this mobo having problems. I have already gotten numerous messages during post that the core voltage on cpu0 and cpu1 were either overvoltage or undervoltage, and after hearing a relatively loud "pop" a few days ago, even more suspicios. Have never seen that with any mobo, and I've been thru a few in the past 30 years. I'd hate to see a pair of 3.0G Xeons get toasted by a faulty voltage regulator, and I still need to investigate the pop noise and see if I can find the capacitor that shot. Never ever will I buy a Tyan board.. just not the quality of the Asus boards. -- Snowman
