Right click acts like left click on my Ubuntu 18.04

Question

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
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]

    ↳ Intel HID events                          id=10   [slave  keyboard (3)]
    ↳ Dell WMI hotkeys                          id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=12   [slave  keyboard (3)]

Solution

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

Just change primary button to left.
