Bug Description
I'm not sure this is gnome shell, as the behavior was also seen in GDM. Except in GDM, the entire screen was upside down in addition to the mouse being inverted.
Upon login to gnome shell, the mouse pointer was upside down, and my movements on the mouse were inverted. Meaning when I moved my mouse up, the pointer went down (using an actual mouse, not a touchpad). I believe left and right worked properly (I can't remember clearly) But when I got the mouse over to the top-right of the screen to turn on wifi (NetworkManager was mysteriously not running -- solved by 'systemctl start NetworkManager' in a terminal), it actually opened up the gnome shell activities menu. Meaning that gnome-shell, at least from my interpretation, interpreted the click as being in the top-left of the screen instead of the top-right. I was able to finally open firefox (I had given up on mouse movement at this point and was using keyboard shortcuts) and googled the problem. I found this page:
I did an 'apt update' and 'apt full-upgrade', and then executed 'apt-get remove iio-sensor-proxy'. The reboot afterward took longer than usual it seemed, but it finally went down. Seeing that removing the iio-sensor-proxy worked, I was trying to figure out what sort of sensor would be triggering this behavior. And then I saw that I had my PS4 controller plugged in, which has the sixaxis sensor in it.
Removing that package fixed the problem. My mouse/screen is no longer inverted, and my PS4 controller (which I'm assuming has the sensor) is still plugged in.

3) I expected screen and mouse behavior to be normal.
4) Screen was upside down on GDM, but correct in gnome-shell. I'm not sure if the mouse movement was correct or upside down in GDM, typically I never touch my mouse during the login process.
