Right Click touchpad sensitivity

[tomfowler]

Making steady progress towards perfection with the PBP.  Almost everything is set perfect.  One thing I'm struggling with is the right click tap "speed".  What I mean by this is that in order to register a right click on the touchpad with two finger tap, the physical tap has to be super fast.  The regular single finger tap to left click works as expected, but using two fingers to right click you have to be very click and deliberate.  It works, but I'd like to fine tune it.  Here is the output of synclient:

Any thoughts on what parameter to change to lengthen the time to acknowledge a right click using two finger tap?
Thanks,
Tom

/sub I'm also interested in this, just received by PBP today and the inability to right-click with two fingers is making it almost unusable for me...

I had the same problem, I am used to a ThinkPad touchpad under Ubuntu.

After some searching and experimentation I found that

Code:

synclient MaxTapTime=225

MaxTapTime was set to 160

This means I get a consistent right click when I tap with two fingers, but YMMV, muscle memory, etc.

I also disabled coasting and changed the min / max speed & acceleration.

Best thing to do is dump synclient output to create a script as per https://www.techrepublic.com/article/twe...-in-linux/

This man page is useful in terms of how the settings work https://www.x.org/archive/X11R7.5/doc/ma...ics.4.html

Very good you found an answer 

I want to use the opportunity to advertise the Wiki

In the last paragraph for the touchpad you see similar advise and there are some more settings that all together make the touchpad quite enjoyable.

The Wiki is actually quite good and has many useful tips.
