Hyprfreeze just reached v1.0.0 - Suspend a game process (and other programs) in Hyprland (streamable.com)

Hello! You may be interested in Hyprfreeze if you game in Hyprland. It's a small script that lets you suspend games just like gaming consoles do.

I always find it annoying when I'm playing and I quickly need to leave my desk or talk to someone, only to die to some random enemy in Elden Ring or to miss (unpausable) cutscenes of a game.

I've built this script to prevent that from happening and over time it's reached a point where I find it robust enough and want to share it with others. Any feedback is always appreciated.

That is really great. I love the setup of the wrapper and how the dependences are listed with a "why".

Am I correct in understanding that the freeze mechanism is a "kill -STOP"? (If so, I feel I need to make more use of that command.)

Indeed. However it's necessary to use that command on both the main PID and all its child processes, otherwise you will run into issues like the game video stopping but the game logic still running in the background.

This is just a tool to automate finding the pid (via hyprctl or other ways) and correctly suspending it.

Brilliant!
