What about HDR? (lemmy.zip)

I'm so done with win11, and currently 12 of my 15 machines are linux anyway, but AFAIK HDR (on nvidia gpu) is still impossible? Are you guys all on AMD or just not using hdr for gaming/media? So instead of relying on outdated info, just asking the pros :)

It's fairly straightforward nowadays and will get even easier this year.

In KDE, you can just enable HDR and hit apply. There's also a calibration tool integrated that is a little bit barebones but it does the job.

For gaming, you currently still need Proton-GE until Valve's Proton ships with the necessary libraries. You can easily download them using ProtonUp-Qt.

Once that is done:

Restart Steam
Right click the game -> Properties...
Set the launch options to PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 %command%
Under Compatibility set the checkmark "Force the use of a specific Steam Play compatibility tool" and select the Proton-GE version you just installed before.

That's it, you can now enable HDR ingame.
