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
