Disabling Sleep / Hybernate / Suspend not working

Buckfae · February 17, 2022, 7:43am

I want to disable sleep / hybernate / suspend on i3. I found How to Completely disable sleep/hibernate/suspend? which tells me to do

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

However, my screen still goes blank after a while. How can i prevent this?
I’m on a fresh install, my pc does not use a password at login (checked that in the installer), just in case that matters.

Thank you very much!

There might be other (better) ways to do this but I installed xfce4-power-manager to manage the power settings of the system:

Set the desired values or disable altogether.

two different things

Display powermanagement is not handled by resume it is handled by xset in ~/.config/i3/config:

          #exec_always --no-startup-id conky
          
          # start a script to setup displays
          # uncomment the next line, use arandr to setup displays and save the file as monitor:
          exec --no-startup-id ~/.screenlayout/monitor.sh
          
          # set wallpaper
          exec --no-startup-id sleep 2 && nitrogen --restore
          #exec --no-startup-id feh --bg-fill /usr/share/endeavouros/backgrounds/endeavouros_i3.png
          
          # set powersavings for display:
          exec --no-startup-id xset s 480 dpms 600 600 600
          
          # disable power saving (for example if using xscreensaver)
          #exec --no-startup-id xset -dpms
          
          # xscreensaver
          # https://www.jwz.org/xscreensaver
          #exec --no-startup-id xscreensaver --no-splash
          
          # Desktop notifications

Modify DPMS and screensaver settings with a command

It is possible to turn off your monitor with the xset command which is provided by the xorg-xset package.

Examples:

Command	Description
`xset s off`	Disable screen saver blanking
`xset s 3600 3600`	Change blank time to 1 hour
`xset -dpms`	Turn off DPMS
`xset s off -dpms`	Disable DPMS and prevent screen from blanking
`xset dpms force off`	Turn off screen immediately
`xset dpms force standby`	Standby screen
`xset dpms force suspend`	Suspend screen

Revision:
There are better ways to do this.

your way works too i would bet?
But seems a bit “bloated” to install power management GUI to disable it in its own settings

pebcak · February 17, 2022, 10:42am

It does.

Buckfae · February 17, 2022, 3:07pm

Thank you, this seems to have done the trick!

Do i need to undo

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

If i recall correctly, this just creates symlinks, should i delete them?

pebcak · February 17, 2022, 3:42pm

If you are not going to use suspension, hibernation etc. you could leave it as it is.
systemctl mask just creates links into /dev/null, that is into “nothingness” sort of.
At anytime later on, you can enable them as needed.

What do i need to to in case that i want to use suspension / hibernation again?

pebcak · February 17, 2022, 7:51pm

You could unmask them at any time (systemctl unmask) enable them and set up the service you need.
Please refer to ArchWiki for power management, suspension, hibernation etc.
