Ubuntu에는 3가지 Suspend, Hibernation 모드가 존재합니다.
- Suspend to RAM (Normal Suspend)
- Suspend to Disk (Hibernate)
- Suspend to both (Hybrid)
위 모드는 systemd에서 target으로 각각 관리하고 있습니다.

각 모드는 mask, unmask를 이용하여 활성화 비활성화 할 수 있습니다.
비활성화 하기
$sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
Created symlink /etc/systemd/system/sleep.target → /dev/null.
Created symlink /etc/systemd/system/suspend.target → /dev/null.
Created symlink /etc/systemd/system/hibernate.target → /dev/null.
Created symlink /etc/systemd/system/hybrid-sleep.target → /dev/null.
활성화 하기
sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
Removed /etc/systemd/system/sleep.target.
Removed /etc/systemd/system/suspend.target.
Removed /etc/systemd/system/hibernate.target.
Removed /etc/systemd/system/hybrid-sleep.target.
