Enable the ThinkPad red dot scroll function in Ubuntu

Enable the ThinkPad red dot scroll function in Ubuntu

In ubuntu, the middle-key scrolling function of the red dot is gone, and it is not used to it. We will start it below,

 

1. One-time change (it will be invalid after restart) 

Save the following script as a sh file, such as trackpoint. Sh.

# ! /Bin/sh
Xinput list | Sed -Ne 'S / ^ [^] [^ V]. * ID = \([ 0 - 9 ] * \). */ \ 1 / P' |   While Read ID
Do
Case 'xinput list - Props $ ID ' In
* " Middle button emulation " * )
Xinput set - Int - Prop $ ID   " Evdev wheel emulation "   8   1
Xinput set - Int - Prop $ ID   " Evdev wheel emulation button "   8   2
Xinput set - Int - Prop $ ID   " Evdev wheel emulation timeout "   8   200
Xinput set - Int - Prop $ ID   " Evdev wheel emulation Axes "   8   6   7   4   5
Xinput set - Int - Prop $ ID   " Evdev middle button emulation "   8   0
;;
Esac
Done

#Disable middle button
Xmodmap-E"Pointer = 1 9 3 4 5 6 7 8 2"

 

Then, change the file property to executable.
Chmod + x trackpoint. Sh

Then execute

./Trackpoint. Sh

 

2. Permanent modification:
Create the following file (if it does not exist ):

/Usr/lib/X11/Xorg. conf. d/20-thinkpad.conf

Add the following content to the file:

Section " Inputclass "
Identifier " Trackpoint wheel emulation "
Matchproduct " Trackpoint "
Matchdevicepath " /Dev/input/event * "
Driver " Evdev "
Option " Emulatewheel "   " True "
Option " Emulatewheelbutton "   " 2 "
Option " Emulate3buttons "   " False "
Option " Xaxismapping "   " 6 7 "
Option " Yaxismapping "   " 4 5 "
Endsection

 

Save and restart ....
