Update tests and version regex

[jinluchang]

Mainly change the regex ".Module ([0-9.]+) ." to ".NVIDIA UNIX.Kernel Module. ([0-9]+\.[0-9]+) ." in file nixGL.nix to accommodate new version string.

Seems like a step in the right direction, once the cachix change is removed. I wonder if we could somehow automate keeping the list of NVidia driver versions up to date?

[dyfrgi]

This change is superseded by #201.

Thank you @jinluchang! I kept getting error: cannot coerce null to a string: null because my /proc/driver/nvidia/version looks like this:

NVRM version: NVIDIA UNIX Open Kernel Module for x86_64  575.57.08  Release Build  (dvs-builder@U22-I3-H04-01-5)  Sat May 24 07:03:13 UTC 2025
GCC version:  gcc version 13.3.0 (Ubuntu 13.3.0-6ubuntu2~24.04)

This PR fixed the issue. I hope it gets merged soon.

The conflicts need resolving first. Since it was left untouched for a while I don't know if @jinluchang is interested in continuing with it. If not, you could pick it up, @samestep.

Oh sure @dyfrgi, I can take a look. I'm guessing I can't edit this PR, should I just open a separate one?

[jinluchang]

@dyfrgi @samestep Sorry for the delay. I have merged the latest change from the main branch and fixed the conflict.

[samestep]

@jinluchang looks like the build is failing?

[jinluchang]

@samestep The failure is due the recent commit "fix: set GBM_BACKENDS_PATH" 3865170

which add "export GBM_BACKENDS_PATH=${lib.makeSearchPathOutput "lib" "lib/gbm" mesa-drivers}" to nixGL.

This change caused the test to fail.

However, the test would work with more recent nixpkgs. Perhaps we should advance the rev in "nixpkgs.nix"?

[samestep]

@dyfrgi is this ready to be merged now?

[samestep]

@dyfrgi are there any blockers for merging this?
