Hopefully future kernel releases don't need the nouveau.modeset=0
option. But until then, 17.10 is rock solid (been full time on it for

As I was not able to login to my computer I am writing this bug report while it runs on kernel 4.10.0-21-generic. Therefore the information attached through the "ubuntu-bug linux" command here, are referring to the kernel that is actually working. I decided to nonetheless include that information as it might contain other kernel unrelated information that would help you troubleshooting.
