Title:
byd touchpad no longer detected
Status in linux package in Ubuntu:
Confirmed
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://launchpad.net/ubuntu/+source/linux/+changelog
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
Any thought on what has changed and how to resolve issue so that I can
upgrade to later version?
Thanks
