Can't disable suspension

Hey! My cousin uses Solus Mate and when she leaves her laptop for a while it suspend and log out, it's annoying bcs it's not a good laptop and it takes time to log in again.

Of course i tried to disable suspension in energy settings (like "suspend after 1 hour, suspend never") but it did not work. I also tried this with no success:

Code:sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.targetAny help would be appreciated, sorry for my english. Thanks!
