how to disable suspension in Ubuntu 20.04?

How can i disable suspension in Ubuntu 20? I think i solved my problem but i wanted someone to look over it.

I applied the following solution:

Code:

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

based on https://askubuntu.com/a/1043652/881300

and this is perfectly working. I now am no longer able to select these options in the power off menu from the desktop.

Is this only disabled for the user or also for the system? I don't have `pm-hibernate` installed.

I tried to apply this solution to additionally disable automatic suspension. But the path to the file does not exist, i think it changed from

`/etc/polkit-1/localauthority/50-local.d/com.ubuntu.disable-suspend.pkla` to
`/etc/polkit-1/localauthority.conf.d/50-localauthority.conf`

but the file contents are very different.

I found this but power settings are no longer available.

As I know, this will disable the functionality.
Try

Code:

systemctl suspend

This should result in an error.

I just tried that and it works:

Quote:

systemctl suspend

Code:

Failed to suspend system via logind: Access denied

Failed to start suspend.target: Unit suspend.target is masked.
