Xorg freeze

[Nikola Chikos]

I can't run Ubuntu 18.10 with nVidia drivers (340.107). They ran just fine on 18.04, but not on 18.10. The system freezes at start up (the furthest that it gets is 'Starting Gnome Display Manager'). X-org Nouveau driver is working ok, but it's not ideal, I get strange flickering at subtle color gradients...
