At random times my display will turn upside down. I'm not sure if I'm touching a key or what is happening.
Probably the Gyroscope having a fit.
You can follow this guide to turn that feature off:
Or permanently disable or remove it with the terminal commands:
sudo systemctl stop iio-sensor-proxy.service
sudo systemctl disable iio-sensor-proxy.service
sudo apt-get remove iio-sensor-proxy
