I had same problem when disabled integrated card in bios. Found issue report in gdm3 https://gitlab.gnome.org/GNOME/gdm/issues/332. Issue description has link back to launchpad https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1716857.
Workaround mentioned in both reports - to change line in gdm.service to ExecStartPre=/usr/bin/xinit /usr/share/gdm/generate-config works for me. ** Bug watch added: gitlab.gnome.org/GNOME/gdm/issues #332 https://gitlab.gnome.org/GNOME/gdm/issues/332 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1705369 Title: Ubuntu 17.10/18.04 boots to black screen when using Nvidia drivers (on a desktop with an Intel GPU) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1705369/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
