Right the same problem on EEepc
But I resolved it :)
there is new file in Kali rolling (daily image from 20.05.16) /usr/share/X11/xorg.conf.d/60-libinput.conf
so, I comment out ### lines from :
Section "InputClass"
Identifier "libinput touchpad cathcall"...
to: EndSection
something is messing with 50-synaptics.conf
so- if it's installed,or persistence you can edit file and restart
if it's only live - unsquashfs ...

Thanks for the feedback emil4o1, unfortunately commenting out the libinput touchpad catachall section in the 60-libinput.conf file didn't work for me... hopefully this is resolved soon though.

Same on my gl552vw-dh71 in 2.0 as well as rolling unfortunately.

check this fix worked for me

Do you have xserver-xorg-input-libinput installed?

Please paste the output of "dpkg -l |grep xserver-xorg-input".

thanks dannyrock777 - your solution worked fine for me, but just for the touchpad click not for scrolling that works with two fingers. furthermore, There is no option in the settings menu nor does it appear in the in the listed devices.
