Thanks, I realize that, hence why I submitted this bug against the Weston
component.

I've also requested the same for KWin and Mutter, see:

No, atomic is still in review.

This is a not thing to be added to Wayland. It is a thing in each compositor
separately.

When will the feature be added to wayland?
I can't believe that a modern display server doesn't have the ability to change
the RGB range!

For the exact case you're describing (legacy X11 clients), eventually but not
immediately.

Daniel,
Will that also address the gamma issue described in Bug 99040?

Yes, once atomic has landed we can start dealing with colour management
properly, including this.

There's a little more to it, especially given that the ->set_dpms() hook is
badly incompatible with atomic, per https://phabricator.freedesktop.org/T7621 -
the DPMS requests arrive completely incoherently to repaint requests, which
makes it difficult to implement correctly.

I guess this is the list of all those "connector properties":

This is a perfectly reasonable feature request IMO. I'd recommend implementing
it after Weston's atomic modesetting series has landed, because there will be a
lot of churn in the DRM-backend.

https://bugs.freedesktop.org/show_bug.cgi?id=96489 says it would be controlled
by a connector property, so it's completely generic. Might also be worth
thinking about how we could allow controlling lots of such properties rather
than just this one.

As for plumbing, it requires some drm-backend specific interface additions in
libweston, and then the actual config reading and setting in weston.

There's no kernel parameter for it, see:

https://bugs.freedesktop.org/show_bug.cgi?id=96489

So if the Wayland compositor does not provide an option to adjust it, you're
pretty much stuck.
