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…
We needed someone like Valve to speed things up.
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
The beta was released late last month, so it should be pretty stable.
