Public bug reported:
I'm not sure if there is any related info in log files because there is
no actual crash or error messages.
Im using Ubuntu 18.04 and Gnome3 on Xorg. Also, I have a NVidia GT520M
with nvidia-390 driver installed through ubuntu-drivers utility. Cant
confirm that is a graphics driver issue because I installed it on a
fresh Ubuntu.
Description
===
Whenever I suspend my laptop (e.g. close lid) and then turn it on, a new
session will be opened in tty2 causing two graphical sessions being
executed at the same time (?)
Workaround
===
I found a workaround that simply requires to Log Out from the 2nd
session (tty2) and pressing Ctrl+Alt+F1 to go back to the original Xorg
session. After that the Login screen will appear.
The background image will get pixelized and very distorted when the 2nd
Xorg session is loaded. Will try to add a screenshot as attachment.
Also, this bug could lead to "bypass" the login menu. I was able to
change session without being asked for user password: one is stuck at
the login screen and the other is logged in already. Not sure if it is a
security issue because it would require a successful authentication
beforehand.
