I am running Ubuntu 14.04 on my Dell Studio 1557. My synaptics touch pad is detected but the scroll functions are not working. The scroll option in the GUI for the mouse and touch pad has disappeared. I have tried reinstalling xserver-xorg-input-synaptics package but receive the following error of Package 'xorg-input-abi-20' has no installation candidate. Please advise for a solution.

Mousepad GUI

The following is the output and I am still unable to install the multi-touch package.

This may be a bug because in 14.04 these options are available via the GUI.

This is a possible solution for you, view the original answer here Enable Edge And Two Finger Scrolling

Quite simple create a script using gedit or a document writer

First open gedit and copy and paste the following :

#!/bin/bash

synclient VertEdgeScroll=1
synclient VertTwoFingerScroll=1

Save the file as scrolling.sh in your ~/bin directory

change the permissions to be able to run it as program open terminal CTRL + ALT + T run this command:

chmod +x ~/bin/scrolling

search for Startup Applications in Dash, and open it then set up scrolling to run when ubuntu starts up.

Try installing the gpointing-device-settings, it worked on my Asus.

sudo apt-get update
sudo apt-get install gpointing-device-settings

It runs from the GUI interface, you will find it in your applications just search for pointing devices, the icon is just a mouse but the app is for touchpad. Has a separate scrolling tab.

Or, from command line

gpointing-device-settings

Actually faster response on my system.

To fix broken packages.

Try Code:

sudo apt-get update

to update your package list. Then Code:

sudo apt-get autoclean

to clean up any partial packages. Then Code:

sudo apt-get clean

to clean up the apt cache. Code:

sudo apt-get autoremove

will clean up any unneeded dependencies. If while doing this you can identify the broken package this code will very forcefully remove it. Code:

sudo dpkg --remove -force --force-remove-reinstreq <package name>

Change package name to the real name of course.

Then

Code:

sudo apt-get install -f 
sudo dpkg --configure -a

This final step is to be sure you have no remaining broken packages.

You should be able to install your packages now.

To completely remove xserver-xorg and re-install do the following.

Remove existing xorg using the following command

sudo apt-get remove --purge xserver-xorg

Install xorg using the following command

sudo apt-get install xserver-xorg

Reconfigure xorg using the following command

sudo dpkg-reconfigure xserver-xorg

Then attempt to install multitouch again.

I just went into system settings and selected "natural scrolling" under the mouse and trackpad options. While the trackpad does not react to the slider bars on the side and bottom, it DOES scroll appropriately when I put 2 fingers on it.

Try disabling two finger scroll. Mine worked perfectly after that as the new 14.04 is prepared to modern Synaptic Touchpads with that feature enabled.

  • I am unable to disable the two finger scroll. Under the settings, I don't have that option available

I had the same problem with my fujitsu laptop. Finally i solved the issue by replacing some code in 

/etc/default/grub

This is my modified file looks.

GRUB_DEFAULT=0       
GRUB_HIDDEN_TIMEOUT=0    
GRUB_HIDDEN_TIMEOUT_QUIET=true       
GRUB_TIMEOUT=10    
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"       
GRUB_CMDLINE_LINUX=""   
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.notimeout i8042.nomux"

then run command 

sudo update grub

Probably it will help you out.
