Synaptics Touchpad scroll not working
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.
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.
