I have the same issue on Ubuntu MATE 18.04 (daily) which uses lightdm, via slick-greeter, as the display manager on my XPS 15 which has Intel IGP and nvidia GTX 960M.
Ever since the upgrade to nvidia-driver-390 vt7 is a blank screen on boot when the nvidia drivers are installed. The only way to get the display manager to present is to entirely remove the nvidia drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1756226 Title: nvidia-driver-390 fails to start GUI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1756226/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
