[Bug 1770396] [NEW] [bionic] Keyboard not working properly and Touchpad not working at all after fresh install on Acer B118

[Matthias Schniewind]

Public bug reported:

After a fresh install of Ubuntu 18.04 LTS on Acer TravelMate Spin B118-RN-P7XQ the Touchpad did not work,although it was firstly working in live mode. The Touchpad was also not displayed when running xinput.
After plugging in a wireless Keyboard (Logitech MK520), working with it and then unplugging it, the laptop keyboard also showed strange behavior:
After logging in into GDM, the Fn buttons seem to be activated permanently, e.g. on the keyboard there is a number pad with Fn keys on the normal keyboard. Instead of typing 'u' I typed '4', instead of 'i' I typed '5', instead of 'o' I typed '6' etc.
The strange thing is that exactly the same keyboard error occurred in Windows 10 before, what was the reason for me to install Ubuntu.
Removing fwupd after reading bug #1717340 fixed both issues: The touchpad is working properly now and the keyboard as well, although the Fn number pad is not working, but all other Fn keys are working.
This is why I decided to link this bugreport to fwupd

Output of xinput after removing fwupd:
