Bug Description
When running on kernel 4.8.0-34 my Lafite byd touchpad is recognised correctly and shows with xinput --list as BYDPS/2 BYD Touchpad.
If I use any higher upgrade, eg 4.8.0-46 in 16.10 then touchpad is only identified as ImPS/2 Generic Wheel Mouse. The same applies if I try 17.04 from an external drive, touchpad does not work and cursor remains in top rh corner of screen.
This could be related to the changelog https:/
4.8.0-36.38 in yakkety-proposed
* Yakkety update to v4.8.13 stable release (LP: #1650581)
...
- Input: psmouse - disable automatic probing of BYD touchpads
