This seems like it should be fairly simple, but has me stumped.
I'm using 10.10 Maverick. I want the screen to dim to about 10-20% opacity after it's been idle for a few minutes and stay that way until the a user comes along.

I've tried quite a few things. Currently, using Screensaver I've unselected 'Activate screensaver when computer is idle' and under Power Management Select 'Put display to sleep... ' both options are set to never. The effect is that nothing ever happens... Screen full bright forever.

From this base, if I change Activate Screensaver... it dims (all the way to black) then immediately to full bright again. I've read multiple reports of this around the web with no solutions given.

In conf-editor under apps->gnome-power-manager->backlight if I set idle_dim_ac selected and idle_dim_time and idle_brightness it doesn't seem to have any effect on this behavior. Fooling with those options and the ones under apps->gnome-screensaver don't seem to net me what I want.

Can anyone suggest where I'm going wrong? Why do Power Management or backlight settings not have an effect when Screensaver is disabled?

update - this is on ac btw on a box, not a laptop. A screensaver that let me dim to input value would work. Any suggestions? – integris May 26 '11 at 15:19
