lid-sleep-daemon v2.0.1
lid-sleep-daemon
A daemon that takes over lid switch handling from systemd and decides more smartly when to suspend
lid-sleep-daemon locks your system immediately after closing the lid, but only suspends after the lid has been closed for a while.
This keeps e.g. your Wi-Fi connection alive, meaning your system is ready to go quicker if you've only closed the lid briefly.
When battery is low, the system is suspended immediately as usual to make sure it does not die while the lid is closed.
Installation
npm i -g lid-sleep-daemonUsually, you'll want to configure your Window Manager / Desktop Environment to autostart the exposed lid-sleep-daemon binary.
Configuration
The following option can be set as environment variables. You will likely want to set at least the CMD variables to match your system configuration! Note: Killing the lock process in the suspend command makes sense if your system is already configured to run another lock process on suspend.
