I have just recently got myself a Dell XPS 9570. I have had no end of trouble trying to get this to work with any flavour of linux. Ubuntu 18.04 seems to get me the furthest.
The only problem I'm facing now is that after about 20mins of use the screen dies with random lines of colour drawn all over making the screen unusable.
I have installed the absolute latest drivers from Nvidia 396.24 (which helped, it was breaking at login before).
Is this just a driver issue or is there some other configuration/setting I can tweak.
