This laptop has a touchpad and a touchscreen. I'm reporting here about the touchpad. One can see from Xorg.0.log and "xinput list" that *two* touchpads are registered by the system one is called "DLL0704:01 06CB:76AE Touchpad" and the other "SynPS/2 Synaptics TouchPad" As a result, syndaemon is not working. To check this, open two terminals, press and hold some key, like "e" in one of them. It starts filling with "eeeeeee". Now while holding the key, use the touchpad to tap on the other terminal. Then "eeee" fills the new terminal. Expected behaviour: tapping on the other terminal should have no effet, the "e"'s should continue to fill the first terminal. Moreover, configuring the touchpad with synclient is not working either. FIX: Since invoking xinput disable "SynPS/2 Synaptics TouchPad" has no effect, it is clear that this one is a "false" touchpad. Hence this fix is: Add an "ignore" section in /usr/share/X11/xorg.conf.d/50-synaptics.conf I added, line 29: Section "InputClass" Identifier "touchpad ignore SynPS/2 Synaptics duplicate" MatchProduct "SynPS/2 Synaptics TouchPad" Option "Ignore" "on" EndSection Now it works. The touchpad is correctly disabled when using the keyboard, and moreover I can configure it using synclient, or adding a file to /etc/X11/xorg.conf.d/ Of course this fix is not universal because I had to use the precise name of the "false touchpad" as reported by xinput. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: san 1743 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=0dbbd1c1-bb58-45af-8c68-716d7ae636e7 InstallationDate: Installed on 2016-06-03 (9 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0c45:670c Microdia Bus 001 Device 003: ID 04f3:20d0 Elan Microelectronics Corp.
