Please post logs from the game.

[ghost]

Please post logs from the game.

My apologies. I am capturing Steam Games and was not sure if the variable would work there. This is the first time I am doing this

[ghost]

Closing as inactive.

[nowrep]

Inactive?

I asked for game logs, you can get it with adding PROTON_LOG=1 to game launch command on Steam.

[kakra]

I'm facing the same problem since I rebooted. I installed obs-vkcapture a few days ago for testing directly compiling from source, and it worked. I then created a system package from it (Gentoo), installed it, removed all the traces from $HOME and rebooted. Now, it no longer works, no matter if I restore the previous situation or don't.

Actually, the dropdown never filled with a list of captured windows for me - it just worked. But I think I may be seeing the same problem. Proton log attached.

That's different issue: [obs-vkcapture] missing device extension: VK_EXT_external_memory_dma_buf

On nvidia proprietary you need to set nvidia-drm.modeset=1 kernel option.

[kakra]

Yeah, I figured that may be a problem. But it is set:

# sudo cat /sys/module/nvidia_drm/parameters/modeset
Y

And vulkaninfo shows it as available:

# vulkaninfo | grep dma
WARNING: [Loader Message] Code 0 : loader_add_layer_properties: 'layers' tag not supported until file version 1.0.1, but /usr/share/vulkan/implicit_layer.d/nvidia_layers.json is reporting version 1
        VK_EXT_external_memory_dma_buf                : extension revision 1

So something is strange here... Okay let's see:

# vulkaninfo | egrep -e "(^GPU|dma)"
WARNING: [Loader Message] Code 0 : loader_add_layer_properties: 'layers' tag not supported until file version 1.0.1, but /usr/share/vulkan/implicit_layer.d/nvidia_layers.json is reporting version 1
GPU id : 0 (NVIDIA GeForce RTX 3080 Ti):
GPU id : 1 (Intel(R) UHD Graphics 770 (ADL-S GT1)):
GPU0:
GPU1:
        VK_EXT_external_memory_dma_buf                : extension revision 1

Okay, so this is on the iGPU only... (which has no monitors attached). So I'll look into the modeset thing. Not sure what happened during reboot.

Thanks for your prompt response. :-)

UPDATE:

# from dmesg:
[    7.358344] [drm:nv_drm_exit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to allocate NvKmsKapiDevice
[    7.358431] [drm:nv_drm_register_drm_device [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to register device

UPDATE 2:

One reboot later, drm registers successful again, capturing works, and I can even select windows this time. Crazy tech... NVIDIA needs to fix their stuff, maybe with 560 which has the kernel-driver open-sourced...

[fsworld009]

I am facing the same issue. The window dropdown has only one option Capture any Window and it never captures anything.

My system is Arch Linux + KDE Plasma 6. OBS is installed via pacman -S obs-studio and AUR obs-vkcapture-git.
Hardware is AMD cpu & gpu.

        VK_EXT_external_memory_dma_buf                : extension revision 1

The log was captured in KDE X11 session, but I'm getting the same issue in Wayland as well.

Is there anything else I should check?

PAC-MAN 256 is 32-bit game, and the pinball probably too. You need to also install 32-bit vkcapture.

[fsworld009]

Thanks, appreciate your quick response. PAC-MAN 256 is working after installing AUR lib32-obs-vkcapture.

For the pinball game it still doesn't work, although that was just a quick test to see if the issue is specific to Steam or not so I'm fine with it for now.

For capturing flatpak apps you need to install vkcapture flatpak, please se README.
