Vulkan/DXVK games in Flatpak on Nvidia GPU won't launch

[YanEx13]

Hello everyone, I'm reaching out here because I have no idea where else to ask for help. I'm experiencing an issue with running games that use Vulkan (DXVK) in Flatpak—they simply won't launch. This affects applications like Steam, Bottles, and Heroic in Flatpak. Initially, I encountered this problem on Fedora 40 and couldn't find a solution. I decided to try CachyOS, but within just a couple of hours, the same issue appeared there as well.

I have a laptop with hybrid graphics, and the problem doesn’t occur when using an external monitor or when switching to an X11 session instead of Wayland. Games that use OpenGL also run without any issues.

Below, I've included links to my bug reports. Any help would be greatly appreciated!

flatpak/flatpak#5802
NVIDIA/open-gpu-kernel-modules#698

Here are screenshots of the errors that appear after launching the games:

Operating System: CachyOS Linux 
KDE Plasma Version: 6.2.5
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1
Kernel Version: 6.12.9-3-cachyos (64-bit)

Memory: 15.3 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics

Does this only affect Flatpak apps? E.g. do you have this problem if you install Steam/Bottles/Heroic through your distro's package manager?

The problem also seems tricky to reproduce consistently, judging by how you've described it here:

I decided to try CachyOS, but within just a couple of hours, the same issue appeared there as well.

In any case, can you try running vulkaninfo and glxinfo inside Flatpak'd Steam just so we can at least check that the discrete GPU is being used?

Here are command line instructions for that (please post the output of the last command only):

Yes, this issue is specific to Flatpak. It doesn't occur with the native versions of Steam or Heroic Games Launcher.

Here are command line instructions for that (please post the output of the last command only):

Judging by both outputs, your NVIDIA GPU is not being used at all...?

Unfortunately, I don't have a laptop with hybrid graphics to debug this, and I also have no idea how they're supposed to work in general, but I at least expected that the discrete GPU would be used unconditionally when running any 3D app...

If I run vulkaninfo in the terminal beforehand, the errors disappear.

But does it still say Intel(R) UHD Graphics (TGL GT1) on the Flatpak side after you run vulkaninfo/glxinfo on the host?

What output do you get if you run vulkaninfo --summary | grep -wm1 deviceName and glxinfo -B | grep 'OpenGL renderer string:' directly on the host instead?

Also, please post the output for each of these commands:

$ cat /sys/module/nvidia/version
$ flatpak --gl-drivers
$ flatpak info "org.freedesktop.Platform.GL.nvidia-$(cat /sys/module/nvidia/version | tr '.' '-')"
$ flatpak info "org.freedesktop.Platform.GL32.nvidia-$(cat /sys/module/nvidia/version | tr '.' '-')"

It seems so, but I can’t say for sure. However, if you run vulkaninfo on the host while Steam is open and then try to launch the game again, it will start. The game runs on the Nvidia GPU, as indicated by Mangohud.

But does it still say Intel(R) UHD Graphics (TGL GT1) on the Flatpak side after you run vulkaninfo/glxinfo on the host?

Yes, that's right.

vulkaninfo --summary | grep -wm1 deviceName

deviceName = NVIDIA GeForce RTX 3060 Laptop GPU

glxinfo -B | grep 'OpenGL renderer string:'

OpenGL renderer string: Mesa Intel(R) UHD Graphics (TGL GT1)

Thank you for providing those.

I still have no idea why that happens, but let's hope that someone who knows what's going on chimes in.

Last update broke launching games for me too, ValveSoftware/steam-for-linux#11697 (comment)

If you have an Nvidia graphics card, try running the following command in the terminal:

sudo systemctl status nvidia-persistenced

If the service is disabled, enable it with:

sudo systemctl enable nvidia-persistenced --now

It seems like this helped me, but I’d like to run a few more tests on other desktop environments.
For some reason, it was disabled on KDE after I installed the drivers.
