It cannot find a resolution (with hints it gets to a point where it
present removing half of the GUI packages as a solution) - if you
remember we had the same problem a month ago or so, and it looked like
it was due to having both amd64 and i386 installed - as with only one
arch (in a chroot) it couldn't be reproduced:
$ dpkg -l | grep nvidia-driver

Leave the following dependencies unresolved:
19) nvidia-driver-libs-nonglvnd recommends libglx-nvidia0 (=
384.111-1~bpo9+1)
20) nvidia-driver-libs-nonglvnd:i386 recommends libglx-nvidia0:i386 (=
384.111-1~bpo9+1)
Accept this solution? [Y/n/q/?]
Using aptitude to switch back and forth seems to work.
