After:

What downsides are there of using that `i8042.nomux=1`? Is any
functionality lost?
If the notebook doesn't implement the Active AUX Multiplexing
specification, then there is no functionality lost.
If it does, and apparently yours doesn't, then you lose the ability to
distinguish between the internal touchpad/touchpoint and an external
connected PS/2 mouse and lose the ability to use any advanced protocol
beyond standard PS/2 mouse.
Apparently the TUXEDO Book BU1406 doesn't have any external AUX port for
mouse, only USB and internally it only seems to have one touchpad, so
there is no need for Active AUX Multiplexing.
If that helps, it can be added to a blacklist based on DMI.
Sounds good.
