Your laptop works with xset dpms force off on a shell? See your energy-saving setting in your environment.

Hey Sean! I’m on Ubuntu 18.10, so I guess it should work. I’m pretty sure Mykle1 is on Ubuntu 16.04.

As far as I know there is no energy-saving settings really. Could you elaborate you answer maybe? :D

I’m not experienced with Ubuntu, but I think there might be DPMS manager (Screen saver, monitor on/off) on X. You’d better check using DPMS enabled.

[mdhenriksen]

@sean So you’re saying there might be a setting that allows for the DPMS being turned on and off, right?

What would be displayed as the result of xset -q ?

[mdhenriksen]

@sean Hey again Sean,

So here’s the output of xset -q:

I noticed the following: Server does not have the DPMS Extension :expressionless_face: Figured that’s why it’s not working. So I’m not sure about this whole DPMS thing. Is it an extension I can install or is it something native to a computer, e.g. hardware?

I’m not expert of this kind, so I might be wrong.

As I know, in nowadays modern linux machine, DPMS is auto detected and enabled if ACPI is also enabled at kernel runtime. However check /etc/X11/xorg.conf.d/ in the Monitor section (Or corresponding alternatives on your environment. Again, I’m not familiar with *nix machines :D )

Option "DPMS" "true"

[mdhenriksen]

@sean Yeah, I’m trying to look into that right now, but without much luck at the moment :D

SOLVED

This is not really a solution, but my error was that I was logged in on “Ubuntu on Wayland” which doesn’t have DPMS.

On the login screen of Ubuntu you can click the little gear-icon and choose what kind of Ubuntu you want to login to. Wayland is a bit restricted, so just go with “Ubuntu” and not “Ubuntu on Wayland”
