DPMS settings override

I am trying to get my screens to turn off. Right now they just blank out. I tried changing settings to get them to turn off but something overrides my settings. I am running gnome 3.36.

xset reports

Screen Saver:
  prefer blanking:  yes    allow exposures:  yes
  timeout:  0    cycle:  0
   DPMS (Energy Star):
  Standby: 0    Suspend: 0    Off: 0
  DPMS is Enabled
  Monitor is On

I tried changing xorg conf to

 Section "ServerFlags"
    Option "OffTime" "10"

No effect

Even when I manually set xset dpms 0 0 500, after a few minutes it gets overwritten back to 0.

I don’t have any screensaver installed. I guess I could install xscreensaver, but I rather find what exactly is overriding my settings. How can I find what is controlling my dpms setting right now?


The preferred method is probably creating your custom config in something like

Section "Monitor"
    Identifier "LVDS0"
    Option "DPMS" "true"

Section "ServerFlags"
    Option "StandbyTime" "0"
    Option "SuspendTime" "0"
    Option "OffTime" "10"
    Option "BlankTime" "0"

Section "ServerLayout"
    Identifier "ServerLayout0"


Like wiki suggests, but it’s overridden.

But thats why I asked … specifically the numeral prefix will have an impact on the order in which the configuration is loaded… hence the 99- in the example above … do you have have such a prefix?

It’s under 10-monitor.conf, but there is no other file to change that setting.
