I think the low level accelerometer logic is somewhere between the Linux
kernel and the iio-sensor-proxy package. Reassigning.

Title:
Screen randomly flips 180 degrees
Status in iio-sensor-proxy package in Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
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.
