On a system I have installed clean F10 the powersave kicks in on the monitor just fine if set in the screensaver area in gnome for a logged in user. However if the user logs out, then the screen blanks out after some period as expected, but the monitor does not go into powersave any any point.
Can someone tell me where the settings are for the timings for these two features of GDM? I presume that this is something that can be set somewhere?

OK I gave up - and changed to kdm - this has a nicer greeter than gdm and does go into powersave correctly after some period which is reasonable.

Well, that's one solution! I've invested a lot of time in a related problem myself. My setup is such that I rarely logout, I just switch back to the gdm greeter after being idle for awhile or explicitly clicking a custom "switch" button. Both run this script:
-------- #!/bin/bash
# Switch back to gdm greeter. gdmflexiserver
sleep 10
# Next line doesn't work. #sudo xset dpms force off
# Try all combinations of gdm xauth files and DISPLAYs. Overkill, but # works.... for file in $( ls /var/run/gdm ); do for (( i=0; i<10; i++ )); do sudo XAUTHORITY=/var/run/gdm/$file xset -display :$i dpms force off done done --------
That's pretty grisly, but it seems to work (if you have sudo set up), turning the monitor off in about 10 seconds. You could probably put something similar in the correct gdm script (that is, if you weren't already using kdm). I always forget which does what when, but one of the directories under /etc/gdm/.
It sounds like the default X dpms settings never kick in for you; does it eventually turn off if you move the mouse or press a key at the greeter screen? Maybe the idle timer needs to be reset by sending an event, assuming it's not starting a fresh gdm X server.
This all feels like black magic, since I don't fully understand how gdm/X/xauth/etc. interact. Maybe the script above will be useful to someone. Or maybe there's a proper way to do it!

OK Reid
I think switching to kdm is the easier (and prettier!) option but we are all entitled to our opinions!

Heh, I don't blame you at all for just switching to kdm. I'm not sure if that would work for me, since as you can see I use gdmflexiserver in my situation. So I got down in the mud a bit.... Anyway, glad to hear kdm works for you!
