How to Completely Disable Suspend/Hibernate in Ubuntu 24.04 | 22.04

Last updated: October 8, 2024 — 4 Comments

This tutorial shows how to completely disable suspend and/or hibernate function, so your Linux computer will never go to sleep.

Linux can automatically go to sleep when system is idle or laptop lid is closed, though user can configure to disable that behavior via either graphical options or logind.conf configuration file.

But, if you never want to sleep your computer, e.g., for server, then you can completely disable this function. So even the suspend option in power-off menu or the corresponding Linux command won’t work!

Auto-run Custom Actions When Waking up Your Ubuntu from Sleep

Last updated: October 8, 2024 — Leave a comment

This tutorial shows how to automatically run custom command, script, or other actions after resuming your Linux PC/laptop from suspend or hibernate.

As you may know, there are quite a few ways to run something automatically at Ubuntu startup. You can use “Startup Applications” utility to run apps or custom commands at login, use crontab to schedule startup jobs, udev rules to auto-configure devices on detection, and systemd-tmpfiles service to auto create, delete, and write configuration files.

But what if your computer does not function properly, or some personal settings do not persist after waking up from sleep?

Without waiting for upstream fixes, you can workaround by creating custom systemd services, to auto-restart the function, or re-configure the settings, and trigger it automatically when waking up from sleep.

This tutorial shows how to enable/disable Keyboard, Mouse, Lid Open, and/or other devices events from waking up your Ubuntu PC or laptop from sleep.

By default, open laptop lid, press any key on keyboard, or press sleep button can wake up your computer from suspend or hibernation state. If you want, you can configure Ubuntu to ignore certain wakeup triggers that you don’t want.
