Could someone explain what these terms mean? I believe these have more to do with laptops than regular PCs. The standby for a laptop would mean the CPU is still moving at full speed, consuming as usual. Suspend means the CPU essentially has stopped. > And while we're at it, does one specify the times since inactivity for > each stage, or the time since the prior stage?

Which of the following > (if any) is correct? > > % xset dpms 600 660 720 > % xset dpms 600 60 60 The last seems more appropriate, per my testing. My monitor samples every six seconds, so I almost went straight to "Off" when testing "% xset dpms 10 10 10". The book on my monitor equates standby and suspend, the only difference being between the two is that one or the other sync is turned off. FWIW, the EPA regulations simply state two shutdown periods and the first of those equates to both standby and suspend for monitors. The second is the "no-sync" power off most monitors do for lack of a signal. -- Kris Kirby UAH Mail <kirbyk@email.uah.edu> UAH CS <kkirby@cs.uah.edu> Home <kris@airnet.net> WWW <nomurphy@hotmail.com> ------------------------------------------- TGIFreeBSD...
