Unable to run gamescope

hdansin

When I launch gamescope, or attempt to use it with any game, I get this:

No CAP_SYS_NICE, falling back to regular-priority compute and threads. Performance will be affected. wlserver: [backend/headless/backend.c:82] Creating headless backend vulkan: selecting physical device 'llvmpipe (LLVM 14.0.6, 256 bits)': queue family 0 vulkan: physical device does not support DRM format modifiers vulkan: physical device doesn't support VK_EXT_physical_device_drm Failed to initialize Vulkan

I have mangohud installed, and it works, so I don't think it is a Vulkan problem. Checked the issues on Github but didn't find anything that seemed applicable. My GPU is a 5500XT.

Has anyone else ran gamescope successfully?

hdansin FWIW with the Vulkan update in the Unstable repository it at least no longer tried to use llvmpipe instead of my actual GPU, but I'm still running into issues with fullscreen mode. It only works seldomly (and randomly), while most of the time it freezes or leads to a black screen. Haven't figured that one out yet.

Looks like itś not picking up the radeonsi driver correctly and instead falling back to the llvmpipe software renderer. I test gamescope with the nvidia driver so can't help you much.

If you tried MESA_LOADER_DRIVER_OVERRIDE=radeonsi gamescope does that work?

It actually appears to have broken itself since the last sync, we're taking a look.

Thanks. Tried the override but no luck.

You don’t seem too far off with the spec with me so I will try it when I’m back home.

I will probably build it from source if it’s in eopkg

Albeit I stopped using gamemode as I found it give me absolute 0% performance increase and as someone who dealt with Feral Interactive personally it makes me question why they even bothered.

Synaptic gamemode

This is actually a different program called game scope.

hdansin baah my bad. Apologies, my stupid ass can’t read

Synaptic Happens to the best of us.

@Staudey Hmm. I ran it on Fedora with no problem (same hardware). So what could be the issue on Solus?

Well, we've already established that it's a software issue (as it worked before).
Now FWIW it seems that there's an open bug related to NVIDIA hardware crashing in fullscreen mode, so maybe the Vulkan update is enough to fix it on your end (as I said, for me the Vulkan update seemed to enable it to auto-select my GPU instead of llvmpipe again, but now it crashes in fullscreen mode on my NVIDIA system)

Update solved it! 👍️

hdansin Nice. Was about to ask you if it did. Good to hear. Now if we could also resolve the issues with Nvidia GPUs, that would be great 😃
