Disable Suspend and Hibernation

If the operation system should not attempt any type of suspend or hybernation, the appropriate targets need to be disabled at the systemd level:

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

Re-enable hibernate and suspend with the following command:

systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target

Restart systemd-login service or reboot:

systemctl restart systemd.logind.service

Check if changes have been applied:

systemctl status sleep.target suspend.target hibernate.target hybrid-sleep.target
