Bug Description
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.
