Any Linux distro do HDR / VRR yet?
Iirc SteamOS JUST added it. So clones of it should be seeing it soon
I've just googled steamos, that's Debian 8 right (which is eol, weird...)
So I'm guessing Debian 8 (and hopefully newer) will get support too soon?
I think thats the old steamos. The current one is arch and isn't quite public release yet but there are a few clones of it.
Kde 6 should have basic hdr...and I can't find it, but I swore I've seen in the past week some gnome based os had some support...
It's been a while for me using a gui for Linux (headless Debian is my go-to)
Does that mean Kubuntu? (KDE Ubuntu) And for VRR (GSYNC/FREESYNC) would Kubuntu also support that do you know?
When I've tried to Google before, it seems like no distro really supports these as well as windows ATM (although the steam OS comment may show things are changing)
VRR (Gsync module at least) works on Ubuntu 23.04 for sure. It's a bit limited though, but it is improving. I was able to get it working by only having one monitor plugged in and running the game in full screen (not windowed). The arch wiki has a very nice write up of the current state. https://wiki.archlinux.org/title/Variable_refresh_rate
I've been using FreeSync for years on Manjaro and Arch.
