# keyman-system-service
|
|
|
|
A DBus system service that allows to access `/dev/input/*` devices
|
|
to toggle capslock and perform other keyboard related actions. This is
|
|
required when running under Wayland, but also used with X11.

## Notes
|
|
|
|
- If we need to limit access to the interface to only Keyman, we can use
|
|
[polkit](https://www.freedesktop.org/software/polkit/docs/latest/polkit.8.html)
|
|
which allows to add a rule with an action that checks for the program.
|
|
|
|
- to see the log file
|
|
|
|
```bash
|
|
journalctl -f -u systemd-keyman
|
|
```
|
|
|
|
- to monitor method calls
|
|
|
|
```bash
|
|
sudo busctl monitor com.keyman.SystemService1
|
|
```
