hi，Kind hearted people

 

ubuntu22 gome desktop

How to configure the default settings of non-stop screen and non automatic screen lock？？

I tried to execute:

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target 

it can only solve the problem of not entering sleep mode！！！
But the screen will still go black,
So how to set the default black screen never???

help ,help

In Gnome settings-> power there should be a "Automatic Screen Blank" toggle which you can switch to disabled. I checked this in a quite new Gnome version (48), not sure what version you have.

Thank you for your support.

but,

Where is the file configured?

 

I want to pre-set it in advance

You can try to change the value via cli:

gsettings set org.gnome.desktop.session idle-delay 0

I don't think you will find text config files for gnome, you should use gsettings or dconf editor.

Take a look here:

 I am Wayland Gnome Ubuntu 22
I executed the command you gave me, but it didn't work

sudo gsettings set org.gnome.desktop.session idle-delay 0

(process:36816): dconf-WARNING **: 12:28:47.991: failed to commit changes to dconf: Cannot autolaunch D-Bus without X11 $DISPLAY

It only works when you are already logged in Gnome, just for your session (no sudo).

 

If you want global settings, you could try setting this via /etc/profile.d/. Create a script like:

 

/etc/profile.d/disable-screen-blank.sh

With the contents 

#!/bin/bash
if [ "$XDG_SESSION_TYPE" = "wayland" ]; then
  gsettings set org.gnome.desktop.session idle-delay 0
fi

and make it executable

sudo chmod +x /etc/profile.d/disable-screen-blank.sh

I tried it and it works for my Gnome 48 test system.
