Title:
Touchpad does not work, "lost sync at byte 6"
Status in linux package in Ubuntu:
Confirmed
Bug description:
Touchpad does not work most of the time. I think it randomly started
working once, but on several other tries/reboots, it does not work.
The device in question:

Using the following workaround I can get it to work, but with limited
functionality:
https://askubuntu.com/questions/922092/lifebook-e546-touchpad-on-ubuntu-16-04
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
The problem with this fix is that two finger scrolling is no longer
possible with the touchpad and the laptop has no other way to scroll.
