DPMS/Screen blanking not working in gnome-shell

The title pretty much sums it up. I've tried setting screen blanking in gnome-control-center->power, but it doesn't seem to work. However DPMS has worked in pretty much every other WM I've tried by default.

I've installed gnome-shell and gnome-control-center. Not using gdm.

I've tried 'xset -dpms' which apparently should've helped at least in earlier gnome releases, but it makes no difference on my system.

Any ideas what could be causing this?

Re: DPMS/Screen blanking not working in gnome-shell

Could you be more specific so as to what does not work? Is it the automatic screen blanking, or just plain screen blanking? If you run

xset dpms force off

does the screen turn off?

Also 'xset -dpms' disables dpms, so I don't understand how that would help.

I want my screen to turn off automatically when system is not in use, so I've enabled the automatic screen blanking from gnome settings.
That command turns my monitor off fine, but doesn't happen automatically when system is idle like it does in other WMs

Also 'xset -dpms' disables dpms, so I don't understand how that would help.

Apparently there's been an issue where xserver's dpms settings get in gnome's way, and disabling dpms with xset has helped some people in arch forums and others. Although if I'm not mistaken that issue should be fixed already.

Re: DPMS/Screen blanking not working in gnome-shell

couldn't figure this out, so the issue with controlling dpms via gnome-control-center persist
however setting the timeout with 'xset s' enables it again for me.
