'Screen Off' Puzzle

[Uber Nooblett]

After about 15 mins, my screens go black (not power saving) and come back when I move the mouse.

While this isn't the end of the world, its pretty irritating, and I cant find where to switch it off. The monitor power saving option is switched off and there is no screensaver or blank screen set on... so whats causing this? any ideas?

Hmm - maybe it is DPMS:

Checking:

:~$ xset q

DPMS (Energy Star):
Standby: 1200 Suspend: 1800 Off: 2400
DPMS is Enabled
Monitor is On

I've never set up the monitors as they are not on the manu list. They are just 2 x plug & play "17 Octigen TFTs with no internal power management

I noticed the 'prefer blanking' option in there is switched on... how does one switch it off? or is that nothing to do with it?

What do you have in the K > System Settings > Monitor & Display ->Power saving tab.

Re: 'Screen Off' Puzzle

Well the power settings thingmy shows switched off.

Unfortunately those 2 codes didn't solve it.

Thanks for trying though
