Excellent. Sounds like GDM's KMS detection needs improving. Finding a KMS device is not sufficient for choosing Wayland over Xorg. GDM should be checking for a monitor plugged into the KMS device too. And if that's not found then fall back to Xorg.
Note that we can't simply make 'nomodeset' installed by default with Nvidia because that would break laptops. Laptops generally have their Intel GPU wired to the screen and the Nvidia GPU logically separate. But the fix to GDM I have suggested should work for all cases. ** Changed in: gdm3 (Ubuntu) Status: New => Triaged ** Summary changed: - Ubuntu 17.10 boots to black screen when using Nvidia drivers + Ubuntu 17.10 boots to black screen when using Nvidia drivers (on a desktop with an Intel GPU) ** Tags added: gnome-17.10 ** Changed in: gdm3 (Ubuntu) Importance: Critical => 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 (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
