Bug Description

I have a HP Pavilion laptop with a Synaptics touchpad. This touchpad has integrated "clicking" buttons.
When I press the right click button, it is correctly registered as right click. However, when I have a finger touching the pad somewhere else (used for scrolling), the right click button is registered as left button (see output of xev below)
I have also provided output of evtest

Use case: I'm moving the mouse cursor with my left hand and then use my right hand to use the right click button. My left hand finger is still touching the pad. When I click the right click button I expect a result accordingly. E.g. right click on the desktop provides a pop up menu.

I have looked at synclient, but not found a setting that solves this (but maybe I didn't look hard enough ;)

Relevant output of XEV:
- I press 'a' on keyboard
- Right click
- I press 'b' on keyboard
- touch pad with finger (nothing registers in xev
- Right click, reported by xev as button 1
- I press 'c' on keyboard

I found a workaround by installing the libinput driver. I did the following:

Remove the synaptics driver:
sudo aptitude purge xsever-xorg-input-synaptics

Make sure the configuration file is gone
sudo rm /etc/X11/xorg.conf.d/50-synaptics.conf

Install the libinput driver and tools
sudo aptitude install xserver-xorg-input-libinput libinput-tools

Restart the x-server

The libinput driver should autoconfigure. Also, the KDE system settings can work with libinput, you might for instance want to enable Tapping.
There are a lot of settings on the Synaptics driver that are not available on the libinput driver, so your mileage may vary. I'm not using most of them so for now I'm going to see what will happen when I use the libinput driver.
