Same here, in a 14.04.5 laptop with both Intel HD Graphics 4400 and
NVIDIA GeForce GT 750M.
After removing all 'nvidia*' packages it boots again to the graphics
environment.
I have also tried to install again the 'nvidia-367' package. Before
rebooting, 'nvidia-prime' says the default is for 'nvidia', so I have
changed to 'intel' instead ("prime-select intel", at terminal). Then
after reboot it goes into the desktop as usual, using the Intel card and
also with all the nvidia modules loaded. However OpenGL does not work
anymore in that case (X fails to load two of the DRI modules on startup,
dunno why).
So I went back and purged all nvidia packages.
Note: I've also tried the package 'nvidia-361' that comes from the CUDA
8.0 repository from NVIDIA, but got the same black screen (still being
able to switch to a text-mode terminal).

Title:
nvidia graphics drivers 367.57-0ubuntu0.14.04.1 prevents gnome from
launching
Status in nvidia-graphics-drivers package in Ubuntu:
Confirmed
Bug description:
Release : Ubuntu 14.04.5 LTS
Package Version : 367.57-0ubuntu0.14.04.1
nvidia graphics drivers version 367.57-0ubuntu0.14.04.1 was published
2 days ago on 11/3 ( https://launchpad.net/ubuntu/+source/nvidia-
graphics-drivers-367/367.57-0ubuntu0.14.04.1 ). I installed the update
on 11/4 (see apt log below). Today on 11/5 I rebooted my machine. Upon
booting when the graphical UI is launched the screen is black. I knew
that though I had no display I was at the graphical login prompt as I
heard the ubuntu sound that's played when the login prompt is
presented. I rebooted into an older kernel version and got the
graphical UI to render such that I could log in. Upon logging in (as
myself or as guest) an error message was flashed and I'm returned to
the login prompt. In looking at /var/log/syslog each time this happens
I'm getting the error
gnome-session[4575]: CRITICAL: We failed, but the fail whale is
dead. Sorry....
After attempting other fixes I found the fix. I removed the nvidia
drivers from the command line with
apt-get remove --purge nvidia*
This resolved the problem. I then went into the graphical proprietary
drivers UI and selected nvidia 367 which re-installed nvidia drivers
367.57-0ubuntu0.14.04.1 I rebooted and the black screen occurred
again. At this point the cause/effect of the nvidia drivers was
apparent. I again removed all nvidia drivers with the apt-get remove
line above. I rebooted and again my system works correctly.
Expected results : To be able to log into Ubuntu after accepting the upgraded
nvidia drivers
Actual results : The new version of nvidia drivers prevents the display from
working or gnome-session from working.
I'm happy to provide any additional diagnostic information that anyone
would like, just ask for files or for me to run commands and get you
output.
