I'm running Mint 17 Mate on a new HP250 laptop. I can turn off the touchpad by typing the following from terminal:

synclient TouchpadOff=1

Now I want to disable the touchpad automatically each time I log on. I tried adding the above line, exactly as shown, to /etc/rc.local by using sudo gedit, but the system still boots with an active touchpad. I'm not too hot on scripting and I don't know if I've used the incorrect format or if I've chosen the wrong file to add this command to. What is the most suitable script file to use and what should the command look like?

Create a file (as 'root'): /etc/X11/xorg.conf.d/synaptics.conf and enter the following:-

Section "InputClass"
    Identifier "Touchpad"
    MatchIsTouchpad "yes"
    Driver "synaptics"
    Option "TouchpadOff"  "1"
EndSection

After a reboot, the touchpad shouldn't work. Note, however, that the buttons (if it has physical buttons) will still work.

  • I am getting an error on line 5 - "1" is not a valid keyword in this section - and X does not load until I change this line. – user277685 Jun 29 '14 at 10:46
  • Try putting the 1 in quotes - "1" or try using "On" instead. – garethTheRed Jun 29 '14 at 10:51
  • Changed line 5 to: Option "TouchpadOff" "1" - works nicely now, thanks Gareth. – user277685 Jun 29 '14 at 11:54
  • This is a good solution but it affects all users. Please add an alternative to disable touchpad on a per user basis (at session startup). I think a .desktop file in ~/.config/autostart would do (so that it runs synclient TouchpadOff=1 or xinput --disable 'SynPS/2 Synaptics TouchPad' where SynPS/2 Synaptics TouchPad is the name of the touchpad device as reported by xinput) – don_crissti Jul 5 '16 at 19:19
