No attempt on x86_64-linux (full log)

The following builds were skipped because they don't evaluate on x86_64-linux: zoom-us

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnfree = true; }
to ~/.config/nixpkgs/config.nix.

@srhb Note that there was previously some problem with Nvidia drivers, due to which mesa was removed from LD_LIBRARY_PATH

#26916

You now reintroduce libGL there - wouldn't that trigger similar problems?

@danbst I don't think so, but I can try to check later today, I happen to have an nvidia card.

@danbst Got a moment to spare to reboot a few times. :)

Tested on NixOS unstable a480887:

• videoDrivers = [ "intel" ] firmware set to integrated only: Works
• videoDrivers = [ "nvidia" ] firmware set to discrete only: Works
• videoDrivers = [ "intel" ] firmware set to optimus: Works with and without bumblebee.

Note that the glvnd changes meant that zoom did not work in either case on master. That said, there might be a better way to add them than what I currently did, suggestions welcome. :)
