Public bug reported: The Vulkan nvidia_icd.json included with the nvidia-384 package has the wrong "library_path" set, meaning that no Vulkan apps can run. For example, running "vulkaninfo" gives the following:
ERROR: [loader] Code 0 : loader_scanned_icd_add: Attempt to retrieve either 'vkGetInstanceProcAddr' or 'vk_icdGetInstanceProcAddr' from ICD libGL.so.1 failed. Cannot create Vulkan instance. /build/vulkan-8TJjRa/vulkan-1.0.61.1+dfsg1/demos/vulkaninfo.c:698: failed with VK_ERROR_INCOMPATIBLE_DRIVER Furthermore, none of our (Feral Interactive) Vulkan games are able to run when this driver package is installed. The library path is set to "libGL.so.1", however since this package includes the GLVND version of the NVIDIA driver, that library is not a valid Vulkan ICD (it is the GLVND dispatch library). The correct ICD library path when using GLVND is "libGLX_nvidia.so.0" (this is what you get when you install the driver manually with NVIDIA's installer). This is seen with nvidia-384_384.90-0ubuntu0.17.04.1_amd64. The nvidia-384 package from the graphics-drivers PPA (version 384.90-0ubuntu0~gpu17.04.1) does not have this problem. However, as of today, the version from the main repository seems to be getting installed as an update in preference to the PPA version, which causes breakage. ** Affects: nvidia-graphics-drivers-384 (Ubuntu) Importance: Undecided Status: Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726809 Title: Vulkan does not work on nvidia-384 due to incorrect nvidia_icd.json To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-384/+bug/1726809/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
