The core issue with the laptops is Xen 4.8 incompatibility (requiring 4.14 instead). Of course, Nvidia is not a factor in our case so maybe this isn't a match for your situation.
In general, when it comes to using open source OSes, I recommend people avoid Nvidia; it is a tightly closed graphics platform.
