Public bug reported:
I am on a Lenovo Flex 14 laptop that includes a 360-degree hinge for
flipping the screen to tablet mode. Upon flipping the screen to tablet
mode the trackpad seems to be disabled but after returning the screen to
90 degrees or laptop mode the trackpad is not re-enabled.
The only way the trackpad seems to be able to be re-enabled is by
restarting the system. Logging out and back does not fix the problem.
The laptop keyboard and touchscreen still work after flipping to
360-degrees and back to 90 degrees/laptop, but, again, the trackpad is
not working after doing this operation of flipping the screen.
Tested on Xubuntu 20.04 and Ubuntu 20.04, which are both in beta.
