Public bug reported:
Previously in 15.10 I had the following rule in
/usr/share/X11/xorg.conf.d/99-no-touchscreen.conf:
Section "InputClass"
Identifier "Touchscreen disable"
MatchIsTouchscreen "on"
Option "Ignore" "on"
EndSection
This worked in disabling the touchpad on my lenovo T440s
After the upgrade to 16.04 I noticed that my touchpad would not work. And I
found the following lines in the log:
[ 3107.956] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad
(/dev/input/event6)
[ 3107.956] (**) SynPS/2 Synaptics TouchPad: Ignoring device from InputClass
"Touchscreen disable"
[ 3107.956] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad
(/dev/input/mouse0)
[ 3107.956] (**) SynPS/2 Synaptics TouchPad: Ignoring device from InputClass
"Touchscreen disable"
So I had to disable the rule in order to be able to use the touchpad,
and now I can't disable the touchscreen.
