Ubuntu – Two finger scrolling and two finger pointer moving if 1 finger is in lower 20%

To get your synclient settings to stick you can add them to xorg.conf. I did this recently for my macbook pro in 12.10 and it works pretty well.

You can also specify a separate configuration file in /etc/X11/xorg.conf.d/ file to keep things neater. Here's a step by step:

1. Create /etc/X11/xorg.conf.d (if it doesn't already exist)

   sudo mkdir /etc/X11/xorg.conf.d

2. Create and edit /etc/X11/xorg.conf.d/10-synaptics.conf

   gksudo gedit /etc/X11/xorg.conf.d/10-synaptics.conf

3. Make it look like the following:

   #Sample /etc/X11/xorg.conf.d/10-synaptics.conf
   Section "InputClass"
     Identifier "touchpad catchall"
     Driver "synaptics"
     MatchDevicePath "/dev/input/event*"
     MatchIsTouchpad "true"
     Option  "SHMConfig"           "true"
     Option  "TapButton1"          "1"
     Option  "TapButton2"          "2"
     Option  "TapButton3"          "3"
   EndSection
   

4. Save and logout/login again. If the xserver fails to load and you get forced into low graphics mode then edit the file again and comment everything out, or mv /etc/X11/xorg.conf.d/10-synaptics.conf ~/10-synaptics.conf.backup and reload again to get back to normal.

For posterity, my current setup for my macbook pro 2012 13" is as follows (warning, I like my touchpad rather sensitive). Try any of these options using synclient before putting them into xorg.conf!

Section "InputClass"
      Identifier "touchpad catchall"
      Driver "synaptics"
      MatchIsTouchpad "on"
      MatchDevicePath "/dev/input/event*"
      MatchProduct "bcm5974"
      MatchIsTouchpad "true"
      Option  "SHMConfig"           "true"
      Option  "FastTaps"            "1"
      Option  "MaxDoubleTapTime"    "100"
      Option  "BottomEdge"          "6000"
      Option  "FingerLow"           "60"
      Option  "FingerHigh"          "90"
      Option         "ClickFinger3" "2"
#      Option         "FingerLow"             "30"
#      Option         "FingerHigh"            "80"
      Option         "VertTwoFingerScroll" "1"
      Option         "HorizTwoFingerScroll" "1"
      Option         "VertScrollDelta" "100"
      Option         "HorizScrollDelta" "100"
      Option         "MultiFingerButton" "2"
      #Option         "TapButton1" "1"
      Option         "TapButton2" "3"
      Option         "TapButton3" "2"
      Option         "MinSpeed" "1"
      Option         "MaxSpeed" "2"
      Option         "AccelFactor" "0.01"
#      Option         "AreaBottomEdge" "5000"
EndSection

This worked on my Asus Q600a.

Remove and re-installing following two packages could solve your issue:

xserver-xorg-input-multitouch
xserver-xorg-input-synaptics

Follow these steps to remove completely and install it again.

Open terminal and execute following command:

sudo apt-get --purge remove xserver-xorg-input-multitouch

be sure you don't remove any other package than xserver-xorg-input-multitouch

sudo apt-get --purge remove xserver-xorg-input-synaptics

again follow the same precaution.

Once removed execute these commands to install it again:

sudo apt-get install xserver-xorg-input-multitouch
sudo apt-get install xserver-xorg-input-synaptics

again be sure you don't remove any other packages while installing it.

Once installed execute following commands to reconfigure it:

sudo dpkg-reconfigure $(dpkg -l | awk '{print $2}' | grep "^xserver" | tr '\n' ' ')
sudo update-initramfs -u

Then restart your system.

There is a GUI application for setting up your touchpad. Mine shows in Dash as "Pointing Devices". Gives you control of most of your touchpad features.

Go to the Software Center and search for "Pointing Devices" that will also be the name in Dash.
