I'm seeing the same problem with my Dell touchpad since upgrading to 16.04. /proc/bus/input/devices shows my touchpad as:
I: Bus=0011 Vendor=0002 Product=0007 Version=01b1 N: Name="SynPS/2 Synaptics TouchPad" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input5 U: Uniq= H: Handlers=mouse0 event6 B: PROP=5 B: EV=b B: KEY=e520 10000 0 0 0 0 B: ABS=660800011000003 The touchscreen is: I: Bus=0003 Vendor=06cb Product=1ac3 Version=0111 N: Name="SYNAPTICS Synaptics Large Touch Screen" P: Phys=usb-0000:00:14.0-6/input0 S: Sysfs=/devices/pci0000:00/0000:00:14.0/usb3/3-6/3-6:1.0/0003:06CB:1AC3.0001/input/input14 U: Uniq= H: Handlers=mouse1 event13 B: PROP=2 B: EV=b B: KEY=400 0 0 0 0 0 B: ABS=260800000000003 Previously MatchIsTouchscreen only matched my touchscreen, but now it's matching the touchpad, too. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1576784 Title: MatchIsTouchscreen also matches touchpads in 16.04 Status in xorg package in Ubuntu: Confirmed Bug description: 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.
