24.04 touchpad how to change/disable middle button

[Jurjen de Vries]

Dear community,

I am trying to change or disable my middle button touchpad (I don't have a mouse). Its annoying that it close tabs in de webbrowser and paste my last clipboard item.
In Ubuntu 22.04 it worked well, I can't remember how I was able to change it here. But following all kind of suggestions such as gnome tweaks and xinput are not working. In xinput it doesn't show my touchpad and in gnome tweaks there is no setting related to this.

Thanks for helping me out.

Best,
Jurjen

The exact way for "how" would depend on the touchpad driver, if the GUI settings built-into 24.04 DE you have loaded don't do it.
It has been a while since I used a touchpad (pre-covid), but there was a synaptic driver for my laptop and I setup two-finger clicking and scrolling to act like the 3rd button. I think this is common. For my desktop on the laptop, I just placed the driver program commands in the autostart file run at X/Session start. But if you have a different driver, then that won't work. You'll need to know the specific program used to manage the touchpad driver settings on your system.

So, almost always, touchpads are controlled through an internal USB connection, so lsusb -vt will show the exact device (in theory).

For example,

$ lsusb -vt
...
    |__ Port 6: Dev 15, If 0, Class=Hub, Driver=hub/4p, 480M
        ID 05e3:0610 Genesys Logic, Inc. 4-port hub
        |__ Port 1: Dev 16, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M
            ID 413c:3016 Dell Computer Corp. Optical 5-Button Wheel Mouse
...

I'm on a desktop now.

Thank you. I have a framework laptop and getting this:

I don't see anything directly nested under Driver=usbhid

I just found the solution by https://askubuntu.com/questions/1405...417258#1417258

Giving this command on the terminal CLI did the trick.

gsettings set org.gnome.desktop.peripherals.touchpad middle-click-emulation true
