Appreciate the info! I had been trying out the new Cosmic DE that ships with pop os and I’m guessing that’s still lacking HDR but did feel very performant. I’ll have to see if switching is worth the trade off once they nvidia driver update gets released

Has support for DP 2.1 or HDR in Wayland made any improvements yet? I tried Pop_OS and had lots of issues with this

I’ve been following this GitHub issue waiting for this change to make it into the next nvidia driver release but still suspect this won’t address HDR. Obviously first world problems for high end hardware but it’s one of the last pieces holding me back from trying Linux on my desktop

Considering they just dropped i486 support this year I’d say you’re running this on a super computer by comparison
