## Systemd support ## Systemd support
xwayland-satellite can be built with systemd support - simply add `-F systemd` to your build command - i.e. `cargo build --release -F systemd`. xwayland-satellite can be built with systemd support - simply add `-F systemd` to your build command - i.e. `cargo build --release -F systemd`.
With systemd support, satellite will send a state change notification when Xwayland has been initialized, allowing for having services dependent on satellite's startup.
An example service file is located in `resources/xwayland-satellite.service` - be sure to replace the `ExecStart` line with the proper location before using it. It can be placed in a systemd user unit directory (i.e. `$XDG_CONFIG_HOME/systemd/user` or `/etc/systemd/user`), and be launched and enabled with `systemctl --user enable --now xwayland-satellite`. It will be started when the `graphical-session.target` is reached, which is likely after your compositor is started if it supports systemd.

## Scaling/HiDPI
On HiDPI displays, xwayland-satellite windows may have small text. Because HiDPI on X11 is very application dependent and hard to solve,
xwayland-satellite doesn't make an attempt to do it for you. However, the same methods that would normally work on X11 should also work
with satellite. See [the Arch Wiki on HiDPI](https://wiki.archlinux.org/title/HiDPI) for a good place start.
