configuration of server outputs through clients

This interface enables clients to set properties of output devices for screen configuration purposes via the server. To this end output devices are referenced by global org_kde_kwin_outputdevice objects.

§outputmanagement (wl_global)

request:

  • create_configuration -> outputconfiguration (wl_resource)

§outputconfiguration (wl_resource)

requests:

  • enable(outputdevice, bool)
  • mode(outputdevice, mode_id)
  • transformation(outputdevice, flag)
  • position(outputdevice, x, y)
  • apply

events:

  • applied
  • failed

The server registers one outputmanagement object as a global object. In order to configure outputs a client requests create_configuration, which provides a resource referencing an outputconfiguration for one-time configuration. That way the server knows which requests belong together and can group them by that.

On the outputconfiguration object the client calls for each output whether the output should be enabled, which mode should be set (by referencing the mode from the list of announced modes) and the output’s global position. Once all outputs are configured that way, the client calls apply. At that point and not earlier the server should try to apply the configuration. If this succeeds the server emits the applied signal, otherwise the failed signal, such that the configuring client is noticed about the success of its configuration request.

Through this design the interface enables atomic output configuration changes if internally supported by the server.
