[SOLVED] Enable button 2 for Kensington Orbit Trackball with scroll ring

rshepard · 07-06-2019, 01:29 PM

Running Slackware-14.2. My very old and favorite Logitech trackball died of old age and I've replaced it with a Kensington Orbit scroll ring trackball: two buttons (left 1, right 3), ball to move the cursor and a ring as a horizontal scroll wheel. Cannot paste highlighted text as the two buttons simultaneously do not function as button 2.

I've checked the buttons using xev and xinput and need an appropriate section for /usr/share/X11/xorg.conf.d/10-evdev.conf. I can post the current contents of this file if desired.

My web searches for 'kensington orbit scroll ring trackball button mapping' and similar find nothing and I'm not a linux hardware guru. Help is needed.

Have you tried this

Code:

Section "InputClass"
        Identifier "Trackball with Middle Button Emulation"
        MatchProduct "Primax Kensington Eagle Trackball"
	MatchIsPointer "on"
	MatchDevicePath "/dev/input/event*"
        Driver "evdev"
	Option "Emulate3Buttons" "True"
EndSection

or

Code:

Section "InputClass"
    Identifier	"Kensignton Trackwheel Middleclick and Scrollwheel Emulation"
    MatchProduct	"Kensington      Kensington USB/PS2 Orbit"
    MatchDevicePath	"/dev/input/event*"
    Driver		"evdev"
    MatchIsPointer	"on"
    Option		"Emulate3Buttons"	"true"
    Option		"EmulateWheel"		"true"
    Option		"EmulateWheelButton"	"3"
EndSection

add this to your /etc/X11/xorg.conf.d/10-evdev.conf

Code:

Section "InputClass"
    Identifier	"Kensignton Trackwheel Middleclick and Scrollwheel Emulation"
    MatchProduct	"Kensington      Kensington USB/PS2 Orbit"
    MatchDevicePath	"/dev/input/event*"
    Driver		"evdev"
    MatchIsPointer	"on"
    Option		"Emulate3Buttons"	"true"
    Option		"EmulateWheel"		"true"
    Option		"EmulateWheelButton"	"3"
EndSection

That should make it work.
if you do not have one then make one.
then edit it as above.

I found this solution using a different search term and put it in 51-kensington-trackball.conf. It works.

Just removed the above file and appended this to the end of 10-evdev.conf.

Thanks very much.
