dpms

[bsouid]

in the fedora 11 feature list it gives the following recommendation for power saving:

Screensaver needs to dpms off the screen, not just make colors black. To turn of monitor after 120s when X is running:

* xset dpms 0 0 120

i pasted this into a root terminal and it works one time but then when i wake it up the next time it reverts to previous settings. is there a place i can set this more perminantly? i searched google and found that it can be set in the xorg.conf file but it seems as though it isnt in /etc/X11/ like normal. the gnome power manager applet does have a setting for this but the minimum it goes to is 6min which isnt good. it really should go down to like 30 seconds.

this happened with fedora 10 too but im using 11 now so i asked it here. also what is the password for the guest account? it would make sense to allow the guest account to log in without a password.

You want the dpms to turn off the monitor every time the system is idle for 30+ seconds?
That would be really hard on the hardware (turning the CRT on and off very frequently causing
a high voltage off/on to the tube and a filament heater cycle each time)
Even with a LCD isn't not a good idea to turn the fluorescent tubes on and off too much.
With the latest LCD with LED backlights, it's irrelevant but they don't need to be turned off
as much anyway (LEDs uses less power and effectively never wear out (200,000 hr life span))

ok maybe i overextended by suggesting 30 seconds, maybe 1 minute is more reasonable. part of the reason why windows gets better battery life is because of stricter screen managment power. the kde power utility can go down to 1 minute; it is very customizable.
