5 years ago You should set NV_DRIVER_PATH to library called "libGL.so.1", that provided by NVidia package in your distro, not libEGL or something else.
I assume it is usr/lib64/nvidia/libGL.so.1 or /usr/lib64/libGL.so.1 Or you can try with
$ find /usr/ | grep -i libgl.so | grep -i nvidia
You can check it is NVidia's libGL by running
$ ldd <library_path> | grep nvidia

5 years ago @snoopcatt Nvidia driver on openSUSE is using GLVND, so libGL.so.1 isn't linked to Nvidia libGL (I've checked this with ldd). But I've found another libGL in /usr/lib64/nvidia directory which has links to Nvidia libs. I'll try change NV_DRIVER_PATH to it and see what happens.
Edit: Nope, still same error. It seems it something with nvidia_icd.json but I don't know what. Path is correct and Vulkan is working on Nvidia with nvidia-xrun (which starts new X.Org session on Nvidia GPU).

5 years ago I'm having the same problem, can't find the GPU.

vkCreateInstance failed.
Do you have a compatible Vulkan installable client driver (ICD) installed?
Please look at the Getting Started guide for additional information.
I have: mesa 19.0.1 vulkan 1.1.100 nvidia 390.116
optirun glxspheres64 works with: OpenGL Renderer: GeForce GT 620M/PCIe/SSE2
and glxspheres64 works with: OpenGL Renderer: Mesa DRI Intel(R) Ivybridge Mobile
I had to change NV_DRIVER_PATH to /usr/lib/libGLX_nvidia.so.0
Tried changing the icd path in nvidia_icd.json to /usr/lib/libnv_vulkan_wrapper.so (since I put it there), didn't work. Same with the library path in /usr/share/vulkan/implicit_layer.d/primus_vk.json.

5 years ago General hint's when the devices cannot be found:
optirun vulkaninfo. These are all devices that the vulkan loader has detected. You need to configure your system until both devices show up here, otherwise primus_vk cannot run.VK_LOADER_DEBUG=all optirun vulkaninfo lets you what the loader thinks when loading drivers.Xlib: extension "NV-GLX" missing on display ":0". indicates that an un-wrapped nvidia libGL.so.1 is used as vulkan driver and it refuses to start. Please configure either libGL.so.1 wrapped with nv_vulkan_wrapper or libEGL_nvidia.so.0 (see #24) as your vulkan driver for the dedicated graphics card. I would also advice to delete the broken ICD configuration from Nvidia, as it can harm other ICDs starting up correctly.felixdoerre

5 years ago Additionally there is primus_vk_diag. You can use this as test utility to ensure that the two graphics drivers are working. Test with optirun primus_vk_diag vulkan. It has to show both devices.

1 year ago I think we've solved all configuration issues mentioned in this issue.
Hello. I've tried to use primus_vk on openSUSE Tumbleweed and it's not working very well. I've changed NV_DRIVER_PATH in nv_vulkan_wrapper.cpp file to "/usr/lib64/libGLX_nvidia.so.0" (location for Nvidia driver on openSUSE), compiled everything without errors, copied compiled libraries to /opt/primus_vk and changed path in nvidia_icd.json and primus_vk.json files to point correct libraries. Now when I'm trying to run Vulkan application (not important which, on every there is same situation) I get error:
No idea what is wrong, everything points to right libraries and I have correct files for Nvidia and Intel GPU in /usr/share/vulkan/icd.d directory.
