Hi yall!
Ever since installing Fedora, I’ve been unable to get HDR working on my Zenbook S16. This was the case for F42 and is still the case in F43. Here’s my version info:
So far, I’ve the guidance in threads such as this to use kscreen-doctor…
cframecollisions@fedora:~$ kscreen-doctor output.eDP-1.hdr.enable
cframecollisions@fedora:~$ kscreen-doctor -o

… with no success. I know my Zenbook is HDR capable, as per the spec sheet :
16.0-inch, 3K (2880 x 1800) OLED 16:10 aspect ratio, 0.2ms response time, 120Hz refresh rate, 400nits, 500nits HDR peak brightness…
Lastly, here’s my display output from inxi -Fzxx as @anothermindbomb suggested (thanks!):

Any suggestions on what I can do?
Post inxi -Fzxx output so we can see what drivers version you’re using. Please ensure this is posted at pre-formatted text (either surround it top and bottom with 3 sequential backticks or use the </> button above).
I have no idea about HDR on laptops, but anyone who does will at least want to see what hardware you’re using down to the driver version level of detail.
You seem to have pasted a very small part of the inxi -Fzxx output into your original post.not by editing an earlier post.

Chris B.:
HDR: incapable
This says your hardware cannot do HDR.
Sorry missed you posted the spec for the laptop.edid-decode program on the edid file in /sys/class/drm for your eDP-1 screen.
For example on my HDR monitor the EDID contains: this
HDR Static Metadata Data Block:
Electro optical transfer functions:
Traditional gamma - SDR luminance range
SMPTE ST2084
Supported static metadata descriptors:
Static metadata type 1
Desired content max luminance: 98 (417.710 cd/m^2)
Desired content max frame-average luminance: 98 (417.710 cd/m^2)
Desired content min luminance: 56 (0.201 cd/m^2)
Sorry about that! Here’s the rest of that output:

I think it would be useful to ask the kde folks why this is not working.https://discuss.kde.org/ ?
Looking there, I found the solution from a KDE developer. ..
This might be 499673 – Laptop internal (OLED) display is not recognized as HDR-capable - some displays only advertise HDR support in a newer way that libdisplay-info doesn’t support yet.
If you put KWIN_FORCE_ASSUME_HDR_SUPPORT=1 into /etc/environment and reboot, it will probably work.
This works on my laptop perfectly. Thank you everyone in this thread for your help!
