Can confirm that without xserver-xorg-legacy my system will refuse to boot when using GDM. It will simply sit at a black screen, never allowing me to log in. With the package installed, GDM seems to work correctly.
Another interesting nugget of information is my initial fix was to simply use lightdm. This introduces another bug whereby on login the display will briefly (for around 5 seconds) show either: a) Pink/white garbled mess b) If I've been logged in recently, what I had on my screen previously. This is even the case if I am booted into another operating system like Windows and then reboot into Ubuntu GNOME. I am using a Nvidia 660ti (GK104) with the Nvidia drivers (375.39). If I can provide any helpful information to the developers, please let me know. I am happy to dump whatever logs are necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1559576 Title: Ubuntu GNOME boots to black screen when using proprietary Nvidia drivers To manage notifications about this bug go to: https://bugs.launchpad.net/gdm/+bug/1559576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
