Hello,

I am struggling with a Dell Latitude 5280 Touchpad.
I do not find the corresponding kernel option, so currently the touchpad is dead.

Already I am not so sure about the brand, as lspci / lsusb does not list something that resembles to a touchpad:

According to:
https://certification.ubuntu.com/catalo ... 4E%3A120B/ the brand is Aquantia Corp. DLL07A6:01 044E:120B
(Never heard of them :-/ )

Thanks in advance!

To spice the answer up a bit, Dell prefers ALPS over Synaptics. A couple of years ago that was a pain in the a.. but works quite nice nowadays.

Confirmed, works fine now ! Thank you very much !

P.S.: I was a bit skeptical first, due to the model number mismatch.
