Monitor not shutting down [SOLVED]

[cool_thing76]

Hi,

I noticed recently after the last punch of updates that my monitor stopped shutting down. I checked the Power Management setting and tried all kind of things but it won't shut down the monitor. Only screen saver works.

Any idea how to fix this?

Check dpms via xset.

In a terminal, type xset q The last three lines of results should be

 Standby: 600  Suspend: 600  Off: 600
 DPMS is Enabled
 Monitor is ON

If dpms is disabled, type xset +dpms and check again.

Re: Monitor not shutting down

Interesting. I have the opposite problem since updating to 4.7.95 -- my monitor has started going to sleep/suspending after a few minutes. Power management stuff in the GUI is still set to not suspend or do anything else with the monitor. Obviously trivial to push the mouse; more of a curiosity.

Just did xset -dpms to see what happens.

Hi,
Thanks for your fast response.

It works fine now.

I did the following:

xset q

and it turns out that dpsm was disabled.

So I did:

xset dpms+

and then noticed that the standby suspend and off times are not what I set in the power managment settings so I changed them for testing to:

xset dpms 60 60 60

and finally the monitor did shut down after 60 seconds.

Thank you so much.

The issue will be whether or not it works again when you reboot.

If you have an /etc/X11/xorg.conf file, add "Option" "DPMS" to the Monitor Section and the System Settings should take over.

If you don't have the file or the above still doesn't work, add the xset command to /etc/X11/Xsession near the top (just below the topmost remarks).

I restarted and it still works fine.

But thanks for the extra tip, I know where to look now if the problem come again.

Hi again

Well, the problem is back again. No matter what I do the settings go back to:

DPMS (Energy Star):
 Standby: 600  Suspend: 900  Off: 1200
 DPMS is Enabled

And worse, the monitor never shuts down.

So I'm trying to modify the xorg.conf file as you described above, but I have no "Monitor Section" and i tried to read about the format of the xorg.conf file and it made me more confused.

Here is my xorg.conf file:

Section "Screen"
	Identifier	"Default Screen"
	DefaultDepth	24
EndSection

Section "Module"
	Load	"glx"
EndSection

Section "Device"
	Identifier	"Default Device"
	Driver	"nvidia"
	Option	"NoLogo"	"True"
EndSection

Where should I add the Option DPMS?

Thanks again

Re: Monitor not shutting down [SOLVED]

Section "Monitor"
  Identifier   "Monitor0"
  Option     "DPMS" "False"
EndSection

or put

xset -dpms

in your .bashrc file
