Ubuntu – Right click acts like left click on the Ubuntu 18.04


After I upgraded from 17.10, right click behaves like left click.

I'm using Dell Vostro 14.

It's always getting this error when I install Ubuntu starting from 16.04 yesterday, the error is still the same… touchpad and click.

Here's the output when I type xinput in my terminal

$ xinput

I also encountered the same problem after upgrading from 16.04 to 18.04. I figured out that there was something wrong with settings.

Mouse & Touchpad settings

Just change primary button to left.
