Daniel, with the latest 17.10 the nvidia problems are now more specific and easier to reproduce. Neither of my Thinkpads gets to the login screen in discrete Nvidia mode iff modeset=1 is used.
In hybrid graphics, the session starts, I suspect this is due to the intel driver being available. If I'm correct, then any machine with only an nvidia card should fail with nvidia modesetting.
