Trackpad on Logitech K400+ wireless keyboard no longer clicks anything when the trackpad is tapped... (tap to click).

This used to work but suddenly stopped. Not sure if this was a mix of Ubuntu + kernel update or not, but didn't work after reinstall either...

I've been struggling to find an answer to why the trackpad on my Logitech K400+ stopped doing Touch-To-Click...

I stumbled across the solution the other day and thought it would be useful to record it here for others...

Basically, all you need to do is to hold the function key (next to super), and click the left mouse button... If it doesn't work first time, try a couple more... Sorted :)

  • Interestingly, it also allows for multi-functions of alt and alt-gr... In Chrome, alt+left/right still nav forward or back a page, but the fun one is that alt-gr+left/right arrow does scroll first if page is scrollable, then nav :) – Rob Hendricks Jan 11 '21 at 07:23
  • omg thanks rob for this answer. I use a macbook pro with this keyboard and it suddenly stopped. I used your trick. Hold the FN key and click a couple of times. Also tried it with the windows key next to it. One of the 2 did the trick – hanneke Jul 11 '21 at 20:28
