I freshly installed Kubuntu 13.10, 32 bit version on newly purchased Dell Vostro 2420. everything is working fine except scrolling and multitouch features through touchpad. I am able to change position of cursor using touchpad and able to tap (single click and double click) but scrolling is not working

I tried to find out solution by searching on google but could not find proper solution to load synaptics drivers.

i am listing some details: Laptop: Dell Vostro 2420 Linux Kernel version and distribution: 3.11.0-12-generic, Kubuntu 13.10

output of xinput list is

Output of synclient -l is

Couldn't find synaptics properties. No synaptics driver loaded?

xserver log and dmesg dont have trace of synaptics

kindly tell me how to troubleshoot this problem.

Had the same problem with a fresh install of Kubuntu 14.04 on a Dell Inspiron 3521, but found a simpler solution. If the system settings tell you that the synaptics driver is not loaded (or not used) when you try to configure the touchpad, simply provide an xorg.conf for it. Turns out, there is a snippet already made for you. It is in /usr/share/X11/xorg.conf.d and it is named 50-synaptics.conf. In my case, there was no xorg.conf in /etc/X11, so I simply copied the snippet as xorg.conf into /etc/X11:

sudo cp -n /usr/share/X11/xorg.conf.d/50-synaptics.conf /etc/X11/xorg.conf

If an xorg.conf already exists, make sure it does not already contain the stanzas for the touchpad, and if it doesn't, append the 50-synaptics.conf snipped to the existing xorg.conf using your favorite editor (and sudo). If it has touchpad stuff in it, you have a different problem.

After re-starting X11 (re-boot would obviously work too), the touchpad worked like a charm.
