    Setting up "Kensington Kensington Slimblade Trackball"[edit]

    xinput version 1.6.2[edit]

    It seems in newer versions of xinput (used in Debian Stretch) use the options ScrollButton and ScrollMethod. Looking at the man page: [1] for inspiration I believe the below config will work.

    Set up via xinput[edit]

    xinput set-prop "Kensington Kensington Slimblade Trackball" "libinput Button Scrolling Button" 8
    xinput set-prop "Kensington Kensington Slimblade Trackball" "libinput Scroll Method Enabled" 0, 0, 1
    

    The first line is telling the xinput system use the upper-right button (Button 8 ) to trigger the navigation mode. The second line is to set the ScrollMethod method to button

    I don't think this is quite the right way to do it but it works for me!


    Via xorg.conf.d[edit]

    Create a file called "23-Kensington_Slimblade_Trackball.conf" in your xorg.conf.d (on Debian Stretch /usr/share/X11/xorg.conf.d/23-Kensington_Slimblade_Trackball.conf) with the below content

    Section "InputClass"
            Identifier      "Trackpoint Wheel Emulation"
            MatchProduct    "Kensington Kensington Slimblade Trackball"
            MatchDevicePath "/dev/input/event*"
            Option          "ScrollButton"          "8"
            Option          "ScrollMethod"          "button"
            Option          "XAxisMapping"          "6 7"
            Option          "YAxisMapping"          "4 5"
    EndSection
    

    Reload the udev rules

    # udevadm control --reload-rules
    


    xinput version ($OLDER)[edit]

    Set up via xinput[edit]

    xinput set-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation" 1
    xinput set-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation Button" 8
    xinput set-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation Axes" 6 7 4 5
    


    The first line is telling the xinput system to enable the mouse wheel emulation (similar to the navigation mode) The second line is to use the upper-right button (Button 8 ) to trigger the navigation mode. The third line make it work for both vertical and horizontal scroll.


    Deprecated method for the same[edit]

    # xinput set-int-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation" 8 1
    # xinput set-int-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation Button" 8 8
    # xinput set-int-prop "Kensington Kensington Slimblade Trackball" "Evdev Wheel Emulation Axes" 8 6, 7, 4, 5
    


    Via xorg.conf.d[edit]

    a very much work in progress but this seems to be working


    Some distributions now support the new Xorg hotplug configuration method via xorg.conf.d directories (in Ubuntu 10.04 Lucid Lynx) instead of hal. In contrast to the udev method below, it should be around for some time, so it might be the best way to “statically” configure scrolling.

    Create the file /usr/share/X11/xorg.conf.d/23-Kensington_Slimblade_Trackball.conf as root with the following content:

     Some systems use /usr/lib/X11/xorg.conf.d instead
    
    Section "InputClass"
    	Identifier	"Trackpoint Wheel Emulation"
    	MatchProduct	"Kensington Kensington Slimblade Trackball"
    	MatchDevicePath	"/dev/input/event*"
    	Option		"EmulateWheel"		"true"
    	Option		"EmulateWheelButton"	"8"
    	Option		"XAxisMapping"		"6 7"
    	Option		"YAxisMapping"		"4 5"
    EndSection
    


    Reload the udev rules

    # udevadm control --reload-rules
