Whelp, gnome doesn’t even support hdr yet, but kde added preliminary support just recently. Also, nvidia added supports for hdr just recently with their v550 driver, released just last month. You probably can run hdr games today if you’re willing to put some elbow grease. I’m lazy though, so I’ll just wait.

Color department? 🤔

Steam isn’t even on wayland - complain about that ticket if you want HDR lol.

not to mention steam actually does have some degree of HDR support through gamescope, which steamdeck ships with.

(also HDR support on linux has barely started being a thing this year…)
