First HDR output signal generated by my Linux box with a hacked version of KWinFT... which is a hacked version of KWin.

#KDE #Wayland

The framebuffer isn't configured correctly for depth 30 (10bpc), but this part already works in X11, and so it can be made to work in Wyaland too.

Actually, maybe I'll just keep it this way... so trippy!

I'm asking the devs on the dri-devel IRC channel and on the KWinFT room on Gitter.

I got it to work! ✌️😄

And this is my work-in-progress patch:

WIP: Initialize HDR output metadata (1b5effdd) · Commits · Bernie Innocenti / KWinFT

This gross hack convinced my BENQ EX3501R to switch to "HDR: ON". Everything is hard-coded, this is only good for a test run. Tested on an AMD Vega 64 card...

2 years passed, and we still don't have HDR color support in any #Wayland compositors 😞

Come on, #KDE & #GNOME! Who will do it first?

@codewiz an interesting site from arch shows, that some work needs to be done, to get HDR working on Wayland.
