Whenever I closed the lid it went to sleep (or hibernation?). Great tutorial, thanks! The other day I installed a music server on an old notebook running Ubuntu Server 20.04.1. Tags Fedora Tips, Ubuntu Tips Post navigation It’s our hope that you found this guide beneficial. This wraps our article on how to disable Suspend and hibernation modes on your Linux system. Be sure to reboot in order for the changes to take effect. $ sudo vim /etc/systemd/nfĪppend the following lines to the file. To prevent the system from going into suspend state upon closing the lid, edit the /etc/systemd/nf file. To verify this, run the command $ sudo systemctl status sleep.target suspend.target hibernate.target hybrid-sleep.target Removed /etc/systemd/system/hybrid-sleep.target. Removed /etc/systemd/system/hibernate.target. Removed /etc/systemd/system/suspend.target. Removed /etc/systemd/system/sleep.target. To re-enable the suspend and hibernation modes, run the command: $ sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target Verify if the changes have been effected using the command: $ sudo systemctl status sleep.target suspend.target hibernate.target hybrid-sleep.targetįrom the output, we can see that all four states have been disabled. You get the output shown below: hybrid-sleep.targetĬreated symlink /etc/systemd/system/sleep.target → /dev/null.Ĭreated symlink /etc/systemd/system/suspend.target → /dev/null.Ĭreated symlink /etc/systemd/system/hibernate.target → /dev/null.Ĭreated symlink /etc/systemd/system/hybrid-sleep.target → /dev/null.ĭisable Suspend and Hibernation in Ubuntu To prevent your Linux system from suspending or going into hibernation, you need to disable the following systemd targets: $ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target This method is much slower than suspending to RAM. The battery is not used and you can safely resume the system from the disk and get ahead with your work. Suspend to both (Hybrid suspend): Here, the machine state is saved into swap, but the system does not go off.However, upon turning it on, everything is restored and you pick up from where you left. Suspend to Disk (Hibernate): In this mode, the machine state is saved into swap space & the system is completely powered off.In this mode, power is reserved for the RAM and is cut from most components. Suspend to RAM (Normal Suspend): This is the mode that most laptops automatically enter incase of inactivity over a certain duration or upon closing the lid when the PC is running on the battery.Sometimes, you may be required to press the power button. Getting back to using your system requires a simple mouse-click or a tap on any keyboard button. Suspending your system helps save power when you are not using your system.
