Title:
display goes blank and system hangs after (and sometimes before) gdm3
login with nvidia-driver-390 and a gtx 970m
Status in gdm3 package in Ubuntu:
Expired
Bug description:
After entering username and password, gnome3 never loads, and instead
you are stuck on a blank screen. Switching tty doesn't work. Sometimes
gdm3 doesn't even load and the blank screen happens before you can try
to log in. Without a workaround, you are forced to boot into recovery
mode and purge nvidia, reverting back to nouveau.
At first glance, this seems similar to this bug:
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-
drivers-390/+bug/1752053/+index?comments=all
However, none of the solutions listed there work and the workaround is to use
lightdm instead of gdm3:
sudo apt install lightdm
If it doesn't ask you to set the default display manager, then do this after,
and set lightdm as the default when prompted:
sudo dpkg-reconfigure gdm3
After that, the system will boot and let you log in normally.
This problem is happening on a Clevo laptop without Optimus, with a
dedicated nvidia gtx 970m device, after installing any of the modern
nvidia drivers from version 390 onward, from the official repo, from
the graphics PPA, and I presume also the official driver from the
nvidia site.
I tested on both Ubuntu 18.04.1 + updates, and Ubuntu 18.10 + updates.
I tested with nvidia driver versions 390, 396, and 415.
gdm3 works fine until you install the nvidia driver.
