Public bug reported:

On a HP EliteBook 840 G3, with Ubuntu 17.04 (the problem does not occur
with 16.04), the display turns at random times by 90° or 180°,
apparently due to the onboard accelerometer picking up vibrations caused
inside the laptop by normal typing on the keyboard while the laptop is
set on a table.

I have tried disabling screen orientation changes in Gnome configuration, to no 
avail:
gsettings set org.gnome.settings-daemon.plugins.orientation active false
gsettings set com.ubuntu.touch.system orientation-lock PrimaryOrientation

The only method that worked was to blacklist the hp_accel kernel module.

There should be at least a reliable way to disable auto orientation.
