Bug Description

I'm running Ubuntu 18.04 on an HP 350 G1 laptop. According to jstest-gtk, the laptop has a ST LIS3LV02DL Accelerometer with three axes. Axes 0 and 2 remain at 0 (center) no matter what I do. Axis 1 on the other hand senses how much the base of the laptop (the lower half of the clam shell, the part with the keyboard), is tilted. When the laptop is level, the Axis's value should be 0, but it can be anywhere from -20 to 20 while the laptop is being typed on. When its reading is above 0, the screen flips. These two facts cause the screen to flip seemingly randomly while it's being used.

Workarround: Lock the screen orientation in GNOME.
