Is Linux not able to switch HDR on and off as necessary?

I usually do this in-game so why would a non-HDR game have an HDR toggle?

    You may have to enable HDR for Linux on each monitor individually from the display settings, and then enable HDR for the game itself from within its own settings.

    I only have 1 (large) monitor. I toggle it on and everything looks like butt. Then toggle it off and it looks normal again. It's an HDR OLED display.

    If you're on KDE, you can use the "sRGB color intensity" to quickly test if your content (e.g. via mpv or Proton) is really in HDR.

    If the content changes while going from minimum to maximum in "sRGB color intensity", it's SDR, if it does not change, it's HDR.

    I also have an OLED monitor and HDR looks fantastic on KDE.

    @domi @artyom Interesting. I didn't think KDE supported it well yet.I'll give it another try, because my gaming rig is the last Windows I have (while still using 50% of the time FreeBSD via ssh and Linux via WSL 🤣) and I'm really fed up with it.

    It's fairly straightforward nowadays and will get even easier this year.

    In KDE, you can just enable HDR and hit apply. There's also a calibration tool integrated that is a little bit barebones but it does the job.

    For gaming, you currently still need Proton-GE until Valve's Proton ships with the necessary libraries. You can easily download them using ProtonUp-Qt.

    Once that is done:

    • Restart Steam
    • Right click the game -> Properties...
    • Set the launch options to PROTON_ENABLE_WAYLAND=1 PROTON_ENABLE_HDR=1 %command%
    • Under Compatibility set the checkmark "Force the use of a specific Steam Play compatibility tool" and select the Proton-GE version you just installed before.

    That's it, you can now enable HDR ingame.

    With my configuration, it does. Though it likely also depends on GPU drivers, Monitor, etc. I'm just speculating as I have no clue beyond "works for me".

    Any games that have an HDR option in their graphics settings would support HDR I hope. Maybe if the display is already in HDR while in desktop mode, it's possible that launching the game isn't able to toggle it off?
