To fix this now without waiting for the Stable Release Update
=============================================================
Install xserver-xorg-legacy
Impact
======
Many users are unable to use their computers after installing the NVIDIA
proprietary drivers to Ubuntu GNOME. Specifically, the log in screen does not
load.
The problem is that many of nvidia-* driver packages do not depend on
xserver-xorg-legacy which is needed for gdm/gnome-shell to work
Test Case
=========
- 1. Check that the nvidia-* packages depend on xserver-xorg-legacy.
+ 1. Check that gnome-shell depends on xserver-xorg-legacy.
2. Optionally, if you have an affected computer, set gdm as the default
login manager (sudo apt install gdm3; sudo dpkg-reconfigure gdm3; sudo
reboot). Does the login screen show up? And can you log in to gnome
(sudo apt install gnome-shell)?
Regression Potential
====================
Low. Installing a missing dependency should cause no issues; if it does,
something is very broken already.
+
+ Other Info
+ ==========
+ The most minimal fix here for 16.04 LTS and 16.10 is to just have gnome-shell
depend on xserver-xorg-legacy. Updating all the nvidia-* packages in Ubuntu and
the PPAs would be a lot more trouble; although that would still be a good idea
so that this gnome-shell dependency could be dropped in future Ubuntu releases.
+
+ xserver-xorg-legacy is a very small package.
Original Bug Report
===================
Using latest Ubuntu Gnome x64 daily build with all updates installed.
Lenovo Z70-80 laptop with Nvidia 840M, BIOS updated to latest version, secure
boot and other potentially problematic BIOS settings disabled.
Can only see a black screen instead of a log-in screen after boot completes
when proprietary Nvidia drivers are installed.
Regular Ubuntu works absolutely fine on the same machine with the same driver
version. Attempting to use older drivers on Ubuntu Gnome made no difference.
Bug is affecting more than just me. We were talking about workarounds in
ubuntuforums. User fthx claims that switching to lightdm fixes the issue
