I have a wacom build-into my fusitsu t-900.
I also have experienced the loss of finger input when upgrading to Xenial.
However the issue was not the kernel itself, but the fact that on the previous
version of ubuntu (15.10) I had to run from my /etc/rc.local:
/usr/bin/inputattach --always -w8001 /dev/ttyS4
In order for the wacom to work.
Now this actually is messing things up. Now It just works without the
inputattach thing.
Can you reproduce the bug on a brand new (live dvd) installation?
my xinput without the inputattach running.
