Are there any packages available to do what auto-HDR does on Windows*? It’ll be pretty limited if not - HDR support in games is still quite disappointing on PC.
*ideally better - my own experience of Windows auto-HDR hasn’t been great, although others seem to have a good time with it
Not sure but probably something Valve could implement in gamescope if they wanted
No. HDR is really something that Valve added. I’m sure there was an attempt before, but it didn’t get very far. KDE is currently in the process of adding HDR to the desktop.
Still in its infancy. Could be awhile before it becomes a normal piece.

I bet Valve will try to add this to Steam Deck.
