I recently installed Kubuntu for the first time on my Thinkpad 440 and there are three issues I'm having with the trackpad:

1) Size of the middle click zone

On Windows, there was a fairly large region I could press and have it be registered as a middle click. On Kubuntu, that region is smaller, and it's screwing up my muscle memory -- I end up left- or right-clicking when I mean to middle click. Is there a way to enlarge the zone that counts as a middle click?

pink zone is what it is on Kubuntu, yellow zone is what I want

2) Top strip

If I begin swiping my finger across this top strip, the cursor doesn't move. It only moves once I bring my finger down to the lower region. If I start in the lower region and move up, it continues to work. Is there a way to disable this annoying behavior and have the entire trackpad work for cursor movement first time?

orange zone is where cursor doesn't move if my finger begins there

3) Dragging

On Windows, if I was dragging an object and moved my finger to the edge of the trackpad, the cursor would continue moving in a straight line until I released my finger. On Kubuntu this isn't the case and I can't find an option to enable it. How do I get this functionality?

(I should also note that these same issues appeared when I tried Ubuntu, so it's not unique to Kubuntu.)

  • What is the Ubuntu version? Did you try libinput? – Pilot6 Jun 10 '16 at 17:43
  • 16.04, no I haven't. I'm a novice so I don't know what that would involve. – dain Jun 10 '16 at 17:49
  • Run sudo apt-get install xserver-xorg-input-libinput, reboot and try. This is another (a new generation) user space driver. – Pilot6 Jun 10 '16 at 17:51
  • No, this has made the problem worse. In addition to the above, now tap-clicking does not work at all and the sensitivity and acceleration are sky-high. I went into the settings menu and everything is now greyed out. – dain Jun 10 '16 at 18:01
  • Tap cliciking is disabled by default in libinput. See http://askubuntu.com/a/678122/167850 You can always remove that package. Acceleration can be tuned too. GUI settings do not work. But I suggest checking other issues. – Pilot6 Jun 10 '16 at 18:13
  • Is there a list of options that can be changed anywhere? The stuff on the libinput site don't look anything like config file you linked – dain Jun 10 '16 at 18:37
  • You can change settings in that config file or using xinput. – Pilot6 Jun 10 '16 at 18:39
  • What are the names of the options to change though? They don't match up with what xinput lists at any rate, because I tried adding "AccelSpeed" "0" in various combinations (with and without spaces, with and without quotes, "False", etc) and it didn't turn off acceleration. – dain Jun 10 '16 at 19:03
  • See http://manpages.ubuntu.com/manpages/wily/man4/libinput.4.html For xinput read man xinput. You can set options there too. – Pilot6 Jun 10 '16 at 19:53

ArchLinux user here. I own a Thinkpad x260, with physical buttons, but i wanted to remove the 'two invisible buttons' at the bottom of my trackpad.

My solution went trought this program:

synclient

Use this to see all configurable options:

synclient -l
