trackpoint left click acts as a left + middle click

[mircodz]

For the couple of months I've been having a really annoying problem:

all of the following diagnostics were obtained thanks to:

Code: Select all

xinput test 10

clicking the left button:

Code: Select all

button press 1 
button press 1 
button release 2 
button release 2 

holding the left button and releasing it after about a second:

Code: Select all

button press 1 
button release 1 

clicking the middle button:

Code: Select all

button press 1 
button press 1 
button release 2 
button release 2 

Additionally to this, while the left click is pressed the cursor locks up and doesn't want to move.

Apparently I'm not the only have that has had this problem, I found this post on the Gentoo forum: https://forums.gentoo.org/viewtopic-t-1 ... art-0.html

What I've tried:

• switching between libinput/evdev drivers
• completely uninstalling evdev
• resetting bios settings to default ones
• booting into a Ubuntu live
• opening up the laptop and cleaning cleaned the contacts
• installing arch Linux from zero

What I haven't tried:

• tests on windows
• flashing the bios
• contact the Gentoo poster for info

Where I'm at:

1. my 20-trackponti.conf:

   Code: Select all

   Section "InputDevice"
       Identifier "TPPS/2 IBM TrackPoint"
       Driver     "libinupt"
       Option     "Device" "..."
       Option     "GrabDevice" "False"
       Option     "EmulateWheel" "true"
       Option     "EmulateWheelButton" "2" 
       Option     "XAxisMapping" "6 7"
       Option     "YAxisMapping" "4 5"
   EndSection
   

2. running the following command will disable the middle button

   Code: Select all

   xinput set-button-map 1 0 3 4 5 6 7
   

3. running the following command on boot will "fix" the cursor lock problem

   Code: Select all

   xinput set-prop "device" "libinput Button Scrolling Button" 3
   

After these fixes I can drag my mouse around while the left button is pressed and this left click press sends the correct signal, but because of how the TrackPoint is mapped, the right click becomes the middle one.

P.S. this is my first post on this forum so if I'm missing something please let me know.

Welcome to the forum.

What I haven't tried:
tests on windows

So test in Windows (just booting a Windows installation image / Preinstallation Environment) should be enough to determine if it's a hardware or software problem.

Most likely your trackpoint buttons are defective in some way. These things should just work out of the box.

I'm sorry for the late reply but I was quite busy and had no spare time. I just booted my x220 for the first time in 5 days. Booted into X and the cursor worked flawlessly! After some time I suspended the laptop and woke it up and the issue returned. Tried restarting and rebooting it but the issue persisted. Any ideas of what it could be?
