hyprfreeze - Pause a game process (or any other process) in Hyprland (github.com)

Hey all! If you do any gaming on Hyprland, you might be interested in hyprfreeze.

It's a very simple bash script I made to "freeze" a game process (or any other process) in Hyprland, which you may find useful to:

  • Pause games during unpausable cutscenes
  • Save system resources (CPU and GPU are free, the process is saved in RAM)

Should just work^^TM in most scenarios but my testings can only go so far and any feedback would be very appreciated.

Does this mean I can pause online games?

/s

/us I'm assuming this is like pressing Ctrl+Z in a Terminal window, and then fg to unpause.

Haha, yes! Ctrl+Z sends a TSPT signal to a terminal process, while this script sends a STOP signal to every process in a game's process tree. Both get resumed with a SIGCONT so they're kinda similar.
