From Sid, version 270....., is always coming up unconfigured. Otherwise, the Sid nvidia driver installation (using dkms) works 100%
Alternatives are set up for the libGl.so.1 but NOT for libglx.so (referring to /usr/share/doc/libgl1-nvidia-glx/README.alternatives). I manually set that up, though apparently not needed, using a previously dpkg-divert'ed libglx.so from xserver-xorg-core. Still get the error.
Is this a bug? Fix? Forget about it?
