** Description changed:
- 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:
+ SRU Request:
+
+ [Impact]
+ Vulkan support is broken because the packages ship a mix of GLVND and non
GLVND GL and EGL libraries.
+
+ [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.
