If I'm not mistaken, there might actually be a bug in the packaging
here. It looks like the libEGL symlink is missing from
debian/nvidia-alternative.postinst.in as shipped in
nvidia-graphics-drivers-legacy-304xx/304.125-2 [1], but it's present
in nvidia-graphics-drivers/340.65-2 [2]. I think that's worth fixing
regardless of whether or not falling back to mesa works.

Regards,
Vincent
