This is expected :( >From what I read (have not tested myself), the Nvidia driver defaults to disabling KMS support. This means Wayland (and hence GDM now) won't work.
So there are three possible solutions I can think of: * Enable Nvidia KMS support by adding nvidia-drm.modeset=1 to your kernel command line. This should make Wayland (and hence GDM) work. It's possibly not the default yet because performance is lower in this mode(?); or * Reinstall lightdm and configure it to re-replace gdm. Then make sure you choose to log in to "Ubuntu" and not "Ubuntu on Wayland"; or * Configure GDM to use Xorg instead (if that's even possible). Then make sure you choose to log in to "Ubuntu" and not "Ubuntu on Wayland". ** Also affects: nvidia-graphics-drivers-375 (Ubuntu) Importance: Undecided Status: New ** Also affects: gdm3 (Ubuntu) Importance: Undecided Status: New ** Changed in: gdm3 (Ubuntu) Importance: Undecided => High ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => High ** Changed in: nvidia-graphics-drivers-375 (Ubuntu) Importance: Undecided => High -- 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 boots to black screen when using Nvidia drivers 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
