Wbg

Super simple wallpaper application for Wayland compositors implementing the layer-shell protocol.

Wbg takes a single command line argument: a path to an image file. This image is displayed scaled-to-fit on all monitors.

More display options, and/or the ability to set a per-monitor wallpaper may be added in the future.

Requirements

Runtime

pixman
wayland (client and cursor libraries)
libpng (optional)
libjpeg (optional)
libwebp (optional)
libjxl (optional)
libjxl_threads (optional)

Note that if SVG support is disabled at least one of libpng, libjpeg, libwebp and libjxl is required.

libjxl_threads is recommended for better performance decoding JPEG XL images

Compile time

Development packages for all the libraries listed under runtime.
wayland-protocols
tllist

Building

meson --buildtype=release build
ninja -C build
sudo ninja -C build install

By default, PNG, JPEG, JPEG XL and WebP support is auto-detected. You can force disable/enable them with the meson command line options -Dpng=disabled|enabled, -Djpeg=disabled|enabled and -Dwebp=disabled|enabled -Djxl=disabled|enabled. SVG support is enabled by default (as it does not require additional dependencies). You can disable it with the meson command line option -Dsvg=false

Derivative work

https://codeberg.org/droc12345/wbg - adds support for directories with images, random, timer flags.
