[PATCH weston 10/11] compositor-wayland: Parse [output] config sections and more options
Jason Ekstrand
jason at jlekstrand.net
Mon Oct 28 04:25:02 CET 2013
This commit makes the wayland backend search through the config for
[output] sections with names starting with "WL" and create outputs
accordingly. Outputs created due to the config file support mode, scale,
and transform parameters. It also listens for the --output-count
command-line option.
This brings the wayland backend almost up to par, in terms of functionality
with the X11 backend.
