weston-debug

The weston-debug client application receives and prints debug messages using the weston-debug protocol. For example, when Weston is recompositing, it prints all surface views and descriptions of the decision process regarding their assignment to overlays and GL compositing.

For weston-debug to work, you must run Weston with the ??debug switch. Do not use this switch in production.

You can pass weston-debug additional parameters to choose categories of debug output to display:

$ sudo XDG_RUNTIME_DIR=/tmp/xdg weston –debug
$ sudo XDG_RUNTIME_DIR=/tmp/xdg ./weston-debug -a

Alternatively, you can enable Weston debug output by setting the environment variable WAYLAND_DEBUG=server, and Weston client debug by setting WAYLAND_DEBUG=1.
