Swaypanion combines different useful features for sway and similar desktop environments.
- brightness setting
- volume control
Start the Swaypanion daemon with the swaypanion command.
If you have installed Swaypanion as a package, you may use the systemd service:
systemctl --user start swaypanion
The following command ensures Swaypanion is automatically started when you log in:
systemctl --user enable swaypanion
The swaypanionc interactive command-line tool may be used to send commands and receive responses. Use the help command in the swaypanionc command-line shell to get the list of all available commands.
Use ":" as a separator between a command and its argument(s). For instance:
> volume set:50
You may provide partial command names, as long as there is no ambiguity. For instance, b d translates to brightness down, however b u could mean brightness up or brightness unsubscribe: in this situation, you may use b up.
If you provide commands as arguments to the swaypanionc command, these commands are executed, without the integrated shell.
For instance:
$ swaypanionc "volume up" "brightness down"
$
TheSwaypanion daemon listens for connections on a UNIX socket, usually in /run/user/<pid>/swaypanion.sock. Its protocol is simple: when a client connects, Swaypanion waits for a command and its arguments. The arguments separator is the group separator (character 0x1d), the end of command is the end of record character (0x1e).
