I'm trying to understand what I am missing for my Steam games to support HDR and I hope someone can help :)
I run openSUSE and are trying to get HDR back in Diablo IV and Palia. The same hardware ran these games with HDR when I used Windows, so I believe these to be a good starting point.
Both my monitor's display menu as well as openSUSE's Display configuration settings page, report that HDR is enabled.
As for Steam, I read somewhere that it was around Proton v9 that HDR support was introduced.
I sat the Steam default compatibility tool to: Proton 11-0-2 today, because Diablo IV started to experience issues with Proton Experimental, where the game would freeze if the monitor was turned off while the game was running.
I've tried to use start parameters: PROTON_ENABLE_HDR=1 DXVK_HDR=1 ENABLE_HDR_WSI=1 %command%
... but the HDR option in the games remain unavailable.
Thanks in advance,

more info is here (External Link: You need to be logged in to view this.)
Don't know what hardware you have proton-cachy says ENABLE_HDR_WSI=1 is only need for nvidia driver versions older than 595.x.x

How could I forget my hardware info 😵
Sorry if this too much information. I have yet to understand how much of the OS-info is important when troubleshooting in Linux 😅
I also tried to add my PC info using the forum's feature for it, as I noticed others had. The forum does not have as detailed options though, which seem important when troubleshooting HDR?
As for Persephone the Sheep's reply:
Yeah... I simply searched around what others had done.
I should have known better than to just use {random gamer person from Reddit}'s solutions without much explanation, but I thought I owed it to everyone to try out some start parameters for HDR before posting here.
In hindsight, I ended up making it more complicated that it had to - Woopsies 😅
Well, I've removed PROTON_ENABLE_HDR=1. I read to use PROTON_USE_WAYLAND=1 - Something about how the info from Wayland had to be passed on into Proton, for HDR to work. Is that right - or would it be better to forget it all and take instructions from you? You seem to know exactly what you are doing :)
If I understand your reply correctly, Vanilla Proton (yet) need something "extra" for HDR to work?

proton-cachyos is
PROTON_ENABLE_WAYLAND=1 %command%proton-ge is
PROTON_ENABLE_HDR=1 PROTON_ENABLE_WAYLAND=1 %command%I can't get vanilla proton to work not sure what I am doing wrong or what the issue would be.
From what I understand vanilla proton is just designed to be used in SteamOS' gamemode so it only works with their gamescope compositor. It's packaged on Tumbleweed so I assume Slowroll has it but seeing as the proton forks are easier to use probably just use them for HDR.
Think I should say vanilla proton doesn't have any wayland options so if you see someone using any its a fork or they don't know they need a fork one or the other.
And the PC info page should be enough for future help in my opinion.

Truly, the open source community, and Linux especially, is so helpful and not at all judgy 😄
It's a whole new world, coming from Windows where everyone has so little patience for a beginner's questions and the default solution to everything is to check file integrity 😅
Again: It is truly appreciated!
Okay, I read your post several times to try and understand it (this girl has a slow brain, sorry!)
Proton-cachyos and proton-ge are not vanilla proton versions, and won't be offered by Steam, right?
So... Because I really want to keep things simple and only rely on Steam and not something third party, I guess I will be going for the gamescope micro-compositor, since that seems to just be something you install and then call using start parameters inside Steam game properties - yes?
I'm currently looking for articles on Gaming On Linux on how that is done.
✏️: Unfortunately no tutorial on GOL, it seems, so I'll have to broaden my search into the vast internet.
Thank you for taking the time to reply to all my questions so far :)

You can install it with this (sorry if you don't like terminal i don't use discover so I don't know if you can install this with discover)
sudo zypper in gamescopeThen in game launch parameter inside steam game properties put
DXVK_HDR=1 gamescope -W 3840 -H 2160 -f --hdr-enabled -- %command%DXVK_HDR=1 enables HDR support even tho it says DXVK its for DX11 and DX12 games don't have a vulkan HDR game to see if this can be left out for those.
Since you have a 4k monitor -W 3840 -H 2160 needs to be added so gamescope runs in 4k, -f puts it in fullscreen, --hdr-enabled does what it says, -- is the end of the gamescope command
What I have put is working for me so I hope it works for you.
(I figured out what my issue was from yesterday)
To explain what proton-ge and proton-cachyos are they are community versions of proton that add features that valve don't want to add like native wayland support or can't add like certain video codecs. They can be install with either ProtonPlus, ProtonUp-Qt or manually. Then selected in the Compatibility section of a games properties menu. Thats the gist of it.
For about 3 years from high school to the pandemic me and my dad ran a computer repair store so I'm just used to doing this. I like doing this lets me learn and I pass the time since I'm unemployed. My friend is also making the switch so anything I learn here may help him eventually. I just wish I was faster at responding I spend way to long thinking about how to write and format my messages.

Your thorough explanations are still very appreciated, even if you are used to doing this :)
Don't worry about the response time, a thorough, well formatted reply is better than a rushed, and thus confusing or easily misinterpreted reply 😊
Unfortunately it didn't work.
I looked into the issue and on Reddit, someone mentioned that this was an issue for them because they ran Steam as Flatpak.
So... Now I am facing another issue entirely, outside the scope of this topic, because I am running Steam as Flatpak.
I will create a new topic for that, to avoid derailing this one :)
The remainder of the post is my reply before I saw yours.
Spoiler, click me
Though I did have some trouble understanding your part about DXVK_HUD=1 but I interpreted it like this:
.
A random character after quote-code was necessary to prevent the next paragraph from showing with no line separation; at least when previewing the post.
I tried to put similar code into the same input box, but then my game would stop running right after Steam registered it running. The following is gamescope code - but before HDR parameters - just to see if I could get it to simply run.
gamescope -w 3840 -h 2160 -- %command%The only thing that does work is only writing gamescope, but that's not really useful 😅

I installed Steam from Zypper.
Using Discover, I was able to confirm that this is installed from the openSUSE Tumbleweed-Slowroll repository, and is thusly not just the Flatpak via console.
For reasons unknown to me, I no longer experienced games crashing using 'native' Steam as I did before I switched to Flatpak.
Super relieved, I then went ahead and moved most of my games from Flatpak-Steam to the 'native' Steam.
In this process, I created a new directory outside of Steam folder
/Home/Sira/Gaming(to avoid the loooong var paths and have a place to store all game related stuff in the future).Then I deleted the Flatpak-version of Steam as well as anything that sounded like it was installed by the Faugus Launched by my previous experimentation, which was mainly winetricks.
Then I went ahead and tested every game I had previously run successfully via Steam (Flatpak) to make sure all the moved (or reinstalled) Proton packs were working properly.
To the exciting stuff: Enabling HDR in game's properties
Now running games with your code:
DXVK_HDR=1 gamescope -W 3840 -H 2160 -f --hdr-enabled -- %command%...no longer crashes the games, but I am not able to see HDR options in-game for any game that supported it on my Windows-installation; or in-case of Diablo IV, the HDR option remains disabled.My questions are now these
Thank you in advance 🫶🏼
