Comment 93 for bug 1705369

Ok found finally a work solution (I bet for most of you :))

Basically skip all the nvidia repository ppa. Install lightdm. Purge gdm3. Follow manual install for the latest driver. Login with lightdm as Xorg.

Now I have shining GTX1060 running on Ubuntu 17.10 :)

BTW I noticed that the ppa drivers do not create /dev/dri/card0! that is the main issue (that loops in Xorg login).

So basically sounds like the ppa are "incomplete" for some of the installation drivers (do they consider the 32 bit libs??)
