Title:
WMI Error - ACPI Exception AE_NOT_FOUND

Status in linux package in Ubuntu:
Confirmed

Bug description:
Backstory: The discrete touchpad enable/disable switch does not work
on Ubuntu but works perfectly on windows. This is probably an issue of
the msi_wmi drivers, so I tried to find a solution.

Followed the instructions here -
