KVM switch & remapped mouse buttons...?

esuhl

I've been using a KVM switch to share my trackball amongst multiple PCs. The two extra buttons on the trackball toggle scroll-mode on/off in Firefox, etc., making up for the lack of a scroll-wheel. Perfect.

However, when I plug the trackball directly into my PC, the two extra buttons now work as page back/forward buttons.

This happens in both Linux and Windows. And whether I connect the trackball to the PC via USB or via the PS/2 adaptor (as I did with my PS/2 KVM).

Does anyone know how I can get rid of the KVM, and keep using the extra trackball buttons to toggle scrolling?

not sure if it will work, try x-mouse button control

There is no creator or source page - sorry

Unless I'm missing something, it seems that the KVM is doing 'different things' with your trackball. Removing the KVM causes matters to return to 'normal'.

Have you an up-to-date driver for the trackball and/or can you reprogram it to do what you want?

Oooh -- nice one! :T

It took a bit of playing about, but remapping buttons 4 and 5 as a "middle-button click" is exactly what I need!

I think this is the homepage if anyone else needs it:

And knowing that's the remapping I need, I "should" be able to figure out how to do that in Linux. I think xorg.conf is deprecated in favour of systemd in Arch(?)... I'll have a read up...

Yeah -- it's strange. I guess the KVM is "designed" for three-button mice, and remaps buttons 4, 5, (and beyond) to button 3 (middle-click)...?

In case it helps anyone, if you're using systemd you can install the libinput driver and create (or append to) this file to remap the buttons in Linux, like this (for example):

/etc/X11/xorg.conf.d/10-libinput.conf

Section "InputClass"
        Identifier      "Marble Mouse via USB"
        MatchProduct    "Logitech USB Trackball"
        Driver          "libinput"
        Option          "ButtonMapping" "1 2 3 0 0 0 0 2 2"
EndSection
