Bug#820013: general: Touchpad not working on Lenovo IdeaPad Yoga 13 after updating from 8.3 to 8.4
Package: general
Severity: important
After running "apt-get update && apt-get dist-upgrade" on 2016-04-03
touchpad of IdeaPad Yoga 13 stopped working. Both touch plate and
buttons are not working.
This laptop also has a touch screen and it is still working without
problems.
I'm not sure which package included this 8.4 update might be the faulty
one.
