10 Minute Screen Blank

[jim_deadlock]

Since upgrading to 12.10 my screen goes black after 10 minutes idle. Where is the setting to change this? I've tried 'brightness and lock' and 'power settings', neither of which have any effect.

I have this option under brightness and lock.

Regards.

EDIT: It's working for me

Hi jim_deadlock

Do you have your screensaver set to activate onto a black/blank screen after 10 mins?

With gnome-screensaver installed I was not able to access any options, even by running gnome-screensaver via ALT-F2 which I found strange. Anyway, I've solved this by uninstalling gnome-screensaver and switching to xscreensaver, which does the job.

However, ideally I would like to power off the screen rather than blank it. Is this possible?

Does xset q in a terminal show anything?

Ok we can now see the 1200 sec (10 min) settings across the board.
What is it you want to do?

[jim_deadlock]

I'd like to power off the display after 30 mins.

I'd like to power off the display after 30 mins.

Ok then I think off after 30mins is best handled by you power management settings.

Now, if I'm understanding your situation correctly your screen currently dims @ 10mins and therefore well before you want your screen turned off at 30mins?

If this is the case you can try ,

xset dpms 3600 3600 3600
xset s noblank
xset -dpms

which should 'disable' dpms for an hour, or if that doesn't work try,

xset dpms 0 0 0
xset s noblank
xset -dpms

which effectively turns off dpms.

The last line of code turns off dpms, however xset behaviour is buggy for some and not others. Go figure!

man xset

will output more information on xset and other options available.
You'll need to see what works for you.
Good luck,.

I have had this problem before and now again..

I would like mine to stay off, but when I do

 xset -dpms

The next time I log back in dpms is back on..

Is there a way to keep it off?
