Support for the ALPS touchpad included in Dell E7270 & E7470 was only added in Linux kernel 4.9, with some issues accidentally introduced in 4.13 and then refixed in 4.15. The fixes were backported to Linux LTS kernels 4.9 & 4.14. Earlier kernels didn't recognize the touchpad and used it in its emulated PS/2 mode, so changing options (like scroll direction, multi-touch gestures, etc.) was not possible.


I followed the Installation guide to get up and running. All the basic stuff seems to work fine.

What does not work

  • Fingerprint reader. The fingerprint reader does not seem to be supported by fprintd or fingerprint-gui yet. I did not put too much effort into searching. The usb id of the fingerprint reader is 0a5c:5834
