3 Button Clickpad - Middle Button Nuisance

English Hardware
1

Hi,

I have a Samsung QX412.

I didn’t have full touchpad functionality with 11.4… Only tapping a left click, with a gesture to use right click…

However everything works with 12.1 but it seems to work too well!
It is detecting 3 buttons, and it is very frustrating to us because of mistaken and unwanted pastings.

Could someone point me in the right direction to disable the middle button for the clickpad??

Cheers

Try going to “System Settings (in Kickoff not YAST) > Input Devices > Touchpad” Then go to the tapping tab and disable tapping with three fingers.
I’m assuming that you are using KDE. You can also try alt+f2 and typing touchpad in the search box. Clicking on touchpad configuration will get you to the touchpad configuration.
If you are using Gnome, I’m sorry that I can’t help there.

Baaaaaam! I had this same problem. Your trackpad is executing a middle-click when it should not be. It’s randomly pasting text in fields that you click in, am I correct? And sometimes, it randomly closes firefox tabs when you click on them…if you had the exact same problem that I did. Then sometimes it opened firefox tabs randomly, too. I finally found a solution to this after it plagued my laptop for a year. It bugged the heck out of me. It has nothing to do with Gnome/KDE. It’s because of a trackpad/touchpad file update. It wants to middle click all the time. All you have to do is add one line and the problem is annihilated. It’s on the forum here somewhere. I’ll post a link next time I go home. Should be in a day or so.

Add the following line to /etc/X11/xorg.conf.d/20-synaptics.con:


Option  "ClickFinger3"  "1"

Bam, problem solved!

Thanks for the replies, however I don’t think I was clear enough.

My issues is that it detects 3 buttons.

When I click around the bottom-center of my touchpad, it registers a middle click.

I would rather find an option of disabling it (the middle button) without resorting to disabling middle-button-paste functionality overall (ie using an external mouse).

Any ideas?

Do you have an option SoftButtonAreas in the file /etc/X11/xorg.conf.d/50-synaptics.conf or any other file in that directory? Whats the value of it?
To disable the middle softbutton you probably want something like
Option “SoftButtonAreas” “50% 0 82% 0 0 0 0 0”
