I'm trying to follow the solution in this thread to disable extra touchpad device so that syndaemon will work to disable the touchpad while typing so I won't keep having a jumping cursor (very hard to type right now)!

Having trouble following the instructions, not familiar with Ubuntu that much. I enter the following: 

sudo gedit /usr/share/X11/xorg.conf.d/51-synaptics-quirks.conf

That opens the text file. I then paste the following:

# Disable generic Synaptics device, as we're using
# "DLL0704:01 06CB:76AE Touchpad"
# Having multiple touchpad devices running confuses syndaemon
Section "InputClass"
    Identifier "SynPS/2 Synaptics TouchPad"
    MatchProduct "SynPS/2 Synaptics TouchPad"
    MatchIsTouchpad "on"
    MatchOS "Linux"
    MatchDevicePath "/dev/input/event*"
    Option "Ignore" "on"
EndSection

Then click save and get the following errors:

** (gedit:6473): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-spell-language not supported

** (gedit:6473): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-encoding not supported

** (gedit:6473): WARNING **: Set document metadata failed: Setting attribute metadata::gedit-position not supported

So not able to fully complete this solution. Let me know if you can help so I can perhaps make this new Dell Inspiron 15 7579 usable (trying both 17.04 on thumb drive and 16.04 LTS on external hard drive).

I've been having the exact same problem. The protocol seems specific to Dell and provides a means to disable the Synaptics driver. So far it is working for me.

Dell Support: Erratic cursor movement on the XPS 13/15 series laptops and Precision Mobile Workstations with Ubuntu 16.04 installed

  1. Open a terminal and run in this command:

     sudo nano /etc/modprobe.d/xps13-9360.conf

    (replace "xps13-9360" with the particulars of your own Dell laptop, i.e. "Inspiron15-7579")

  2. Type blacklist psmouse and press Enter

  3. Press Ctrl+X to save.

  4. Press Enter to verify the changes made to the file name.

  5. You should now be back to the terminal. Type the command sudo update-initramfs –u && sudo reboot and press Enter
