title: Disabling TouchPad on Ubuntu 18.04 (Temporarily)
body: <p>I was using Ubuntu 16.04 on my System76 Oryx laptop.  The trackpad is very sensitive so I used to disable it using Fn+F1.  That is not working anymore in 18.04.  I looked around and found:</p>
  
  <pre><code>synclient TouchpadOff=1 
  </code></pre>
  
  <p>When I set that it seemed to work for a second then reset...</p>
  
  <pre><code>$ synclient TouchpadOff=0
  $ synclient | grep TouchpadOff
      TouchpadOff             = 0
  $ synclient | grep TouchpadOff
      TouchpadOff             = 1
  </code></pre>
  
  <p>I also found:</p>
  
  <pre><code>xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0
  </code></pre>
  
  <p>But that seems more permanent.  When I tried to set back to 1, it remains off.  Seems I need to reboot now to turn it back on.  I used to be able to toggle with Fn+F1.</p>
