System sleep

Omarchy enables suspend and hibernation by default, but if you're having issues with either on your machine, you can toggle them off.

Toggle suspend

You toggle suspend by running omarchy toggle suspend from the terminal. That just reveals/hides the option under System (or Super + Esc), and then you can see if it works consistently on your system. If not, you can hide it again with the same command.

Toggle hibernation

You set up hibernation by running omarchy hibernation setup from the terminal. Hibernation creates a /swap subvolume on your boot drive the size of your physical RAM allocation, so make sure you have plenty of room to spare. On a 32GB machine, you'll always need 32GB+ free for this volume. Hibernation also requires the default Limine bootloader.

When set up, you'll see the hibernate option under System (or Super + Esc), and then you can see if it works consistently on your system. If not, you can remove it again by running omarchy hibernation remove.
