Scott Moreau added in an [output] section to Weston's main config file that allows for outputs to be configured. From the general Weston config file this now allows for outputs to be specified to a specific mode (WIDTHxHEIGHT), off, preferred (the native mode), or current (whatever the mode is currently set to when launching Wayland). The Weston config file is formatted in a simple INI-style text file.
Below is an example of what the output configuration for Wayland/Weston could look like:
[output]The latest patch for this output config support is currently on the mailing list but Kristian Høgsberg has expressed interest in already pulling this support to the Weston Git repository.
