Avoids crashing, and GTK apps also seem to generally dislike when the reported DPI is less than the default. Fixes #181 |

xwayland-satellite
xwayland-satellite grants rootless Xwayland integration to any Wayland compositor implementing xdg_wm_base and viewporter. This is particularly useful for compositors that (understandably) do not want to go through implementing support for rootless Xwayland themselves.

Dependencies
- Xwayland >=23.1
- xcb
- xcb-util-cursor
- clang (building only)
Usage
Run xwayland-satellite. You can specify an X display to use (i.e. :12). Be sure to set the same DISPLAY environment variable for any X11 clients.
Because xwayland-satellite is a Wayland client (in addition to being a Wayland compositor), it will need to launch after your compositor launches, but obviously before any X11 applications.
Building
# dev build
cargo build
# release build
cargo build --release
# run - will also build if not already built
cargo run # --release
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.
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
For most GTK and Qt apps, xwayland-satellite should automatically scale them properly. Note that for mixed DPI monitor setups, satellite will choose the smallest monitor's DPI, meaning apps may have small text on other monitors.
Other miscellaneous apps (such as Wine apps) may have small text on HiDPI displays. It is application dependent on getting apps to scale properly with satellite, so you will have to figure out what app specific config needs to be set. See the Arch Wiki on HiDPI for a good place start.
Satellite acts as an Xsettings manager for setting scaling related settings, but will get out of the way of other Xsettings managers. To manually set these settings, try xsettingsd or another Xsettings manager.
Wayland protocols used
The host compositor must implement the following protocols/interfaces for satellite to function:
- Core interfaces (wl_output, wl_surface, wl_compositor, etc)
- xdg_shell (xdg_wm_base, xdg_surface, xdg_popup, xdg_toplevel)
- wp_viewporter - used for scaling
Additionally, satellite can optionally take advantage of the following protocols:
- Linux dmabuf
- XDG activation
- XDG foreign
- Pointer constraints
- Tablet input
- Fractional scale
