[Test Case] 1) Enable the -proposed repository, install the new nvidia-384 package, and reboot. 2) Install the utilities to check that the correct libraries can be found: sudo apt install vulkan-utils mesa-utils-extra 3) Run and attach the output of the following commands (which should execute with no errors): vulkaninfo es2_info [Regression Potential] Low, as the libraries are the same that are installed by the upstream NVIDIA installer when the non-GLVND parameter is used. ________________________ 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.
