I had the same issue on my Asus N552VX laptop. Installing 367.27 from nvidia-367 worked fine after running prime-select intel but prime-select nvidia would lead to the login loop issue people have noted here. Once logged in via the intel graphics option nvidia-settings wouldn't load.
nvidia-xconfig dpkg-reconfigure gdm3 from Ctrl + Alt + F1 shell fixed the issue for me. The driver is still broken as multiple screens don't work under nvidia mode, but I can get away with playing games under nvidia mode and working under intel mode. -- 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 on a laptop with Optimus 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
