(Fedora) Lenovo Thinkpad T440 T450 T460 – Fix Trackpoint Scrolling And Left Button

Published on Author gryzliLeave a comment

The Problem

I was using Fedora 23 happily with my old Thinkpad T520 and all of my trackpoint “stuff” was working just fine.

After buying a new T460, suddenly I faced some trackpoint-related problems:

First: The middle trackpoint button stopped scrolling anything

Second: The left trackpoint button stopped working for marking text (only double-clicks were fine)

 

The following fix must be working on T440,T450, T460 (maybe the T5XX series also)  also it must be working for Fedora 21-23.

The Fix

In order for the fix to work you need to do 2 things:

  • Create X11 config file for the trackpoint
  • Change kernel boot option psmouse.proto

Create X11 config file

Create the file /usr/share/X11/xorg.conf.d/11-trackpoint-wheel-emulation.conf and put the following content:

 

Add the kernel option

First you need to edit the default grub2 settings in /etc/default/grub

  • Find your “GRUB_CMDLINE_LINUX=” line and make sure it contains “psmouse.proto=bare

 

Finally you must re-generate your grub2 config in order to include the psmouse.proto=bare option. You can do this by running the following command:

$ grub2-mkconfig -o /boot/grub2/grub.cfg

 

You can make sure everything is fine, by grepping for the option in your grub2 config:

grep "psmouse" /boot/grub2/grub.cfg

 

Finally reboot the system

That must be all you need.
