Right now I am pretty frustrated with HDR under Linux. Well frustrated may be the wrong word, but it is the thing right now that gets me to boot into Windows to play games that have HDR.
I am wondering if I would have more luck using the deck variant for HDR because apparently Valve has this figured out before everyone else.
Kind of the boat I am in.
Just want my gaming desktop to work and be stable. Or at least more stable then my current rolling release, Tumbleweed.
I do have an AMD GPU, so that sounds like it will make things easier.
Are you running the -deck variant that gives you a Steam deck experience that has a DE for “desktop mode” or just the version with a more traditional DE?
I had a pretty bad experience with Nobara where KDE was super unstable. Probably hardware specific, but when I switched off it everything was stable.
GPU is Radeon 7900xtx, so pretty new.
I may switch back to distro Steam. I was trying to get as much Flatpaked as possible but getting HDR working is more important to me.
Yeah I was running the game under Plasma 6 with HDR enabled and inside a game scope container.
Sounds like there are some issues with Flatpak and HDR so that may be what I am hitting.
What additional configuration are you referring to?
I got it to engage, the game thinks it’s running in HDR but it just looks really bad
Ah - thanks for the heads up about the Flatpak version. I have everything running in Flatpak, Steam as well, so that may be why I’ve had zero luck with HDR.
Got it working, added to -f --hdr-enabled to the Additional Options section under the upscale options in the Gamescope tab. Note that you need to have upscape ticked even with additional options added.
Unfortunately it looks washed out and awful.
Edit: Just a quick note for folks this later on - it does indeed seem Flatpak related, or at the very least I got similar results under the Steam flatpak trying to run game in HDR. I ended installing the native package Steam and lo and behold, HDR no longer looks as washed out, though it still looks a little off compared to Windows. Those swapchains errors I was getting also vanish.
I wouldn’t have thought to try that, thanks. Can confirm it looks like it is running Gamescope now. However I am still not getting an HDR switch in Alan Wake 2.
Getting the following errors:
“CreateSwapchainKHR: Creating swapchain for non-Gamescope swapchain. Hooking has failed somewhere! You may have a bad Vulkan layer interfering. Press OK to try to power through this error, or Cancel to stop.”
“QueuePresentKHR: Attempting to present to a non-hooked swapchain. Hooking has failed somewhere! You may have a bad Vulkan layer interfering. Press OK to try to power through this error, or Cancel to stop.”
Thanks! I actually have that installed already.
How do I tell Heroic to launch the game under gamescope vs the normal compositor?
Game is Hunt Showdown and they don’t have sharpening as an in game option.
I will take a look at vkBasalt. Little worried that could trigger a ban from their anti-cheat.
So can you just swap compositors for Gnome or is Gnome reliant on their own compositor (Mutter)?
Actually on Tumbleweed right now. I’ve been generally impressed but my suspend broke out of no where and it’s the latest in a long line of (mostly) minor things breaking with updates. The upside with how fast the updates are is that usually things are fixed as quickly as they break but suspend has been broken for me for about 3 weeks now.
I honestly just don’t think rolling distros are for me. Or at least, not for my use case of chill out during my downtime and play a game PC.
