Description: NVIDIA OpenGL/GLX/EGL/GLES GLVND libraries and Vulkan ICD
This package provides the NVIDIA OpenGL/GLX/EGL/GLES libraries and the
Vulkan ICD.
when attempting to pin libnvidia-gl-440 to version 440.59-0ubuntu0.18.04.1,
I discovered that version 440.100 gets installed for libnvidia-compute-440 and
libnvidia-common-440. This causes applications to break, because NVRM expects
exact matches between the kernel
driver version (440.59) and the libraries:
[ 720.451125] NVRM: API mismatch: the client has the version 440.100, but
NVRM: this kernel module has the version 440.59. Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.
I've worked around this locally by looking up the dependencies of
libnvidia-gl-440, and pinning those with exact-matches as well.
This could be resolved by specifying these dependencies inside the
package as exact matches.
