Are there any distro besides steamis (and by extension chimera) that’s support hdr? Or do you just need to launch the game in full screen so it takes over?
I know that KDE is working on HDR support for Plasma 6 (Wayland). Dunno how ready it’ll be by the time it comes out, but its coming.
Other than Plasma 6, I don’t think so.
Release date should be around February and it already has a beta, so it’s probably safe to go test in now.
If you’re using an AMD GPU, you can try using gamescope as your desktop session.
I built a couple of HTPCs like 7 years ago or something. Kaby Lake iGPU had support for 4k HDR so I figured I would use the i3 7100T and Linux would add HDR support soon (I was using LibreELEC which was a minimal Linux that just boots into Kodi). Welp still waiting…
Not sure if it’s supported on x86 but CoreELEC has had support for HDR on most modern ARM chips for a while now.
I use a Odroid N2+ as HTPC and play 4k HDR content with no issues.
Any distro that has access to KDE plasma6 alpha can support hdr
