Does
xset dpms force off
work and/or is the screen re-activated after a short time (w/o your interaction)?

tweaking things in the GUI worked perfectly before.
not sure if this is related but i have noticed that after some updates ( but i can't pinpoint which ) i have to enable triple buffering in the xorg.conf and also some other things i can't recall at the moment. I'm guessing this is one of these moments, but other things were affected - any tips on how to prevent this in the future ? probably i'm not doing something right

Any chance that some application turns off DPMS? (video players are prone to this)
What's the "xset -q" output right after the login and what happens if you pass
xset dpms 30 45 60
xset +dpms
(your screen should turn off after 30 - 60 seconds, depending on how it reacts to what DPMS signal)
Is this reset (turned off) at some point after?
Otherwise there's likely a bug in the settings GUI

immediately after a reboot this is the xset -q output
[jordan@Workstation ~]$ xset -q

worked correctly
i guess the GUI is bugged, i just used xset dpms with the desired values and it's working now, thanks!

Is the powerdevil daemon running?
In any case, I'd suggest to file a bug upstream (notably since this seems a very recent regression?)

Do you have a chrome/chromium session with a video (or for that matter a flash ad ) running? Chromium will send monitor inhibition events if that is the case and powerdevil will honor these.
