The touchpad on my Thinkpad X1 Carbon was way too sensitive.
I changed the synaptics settings, to get ride of this annoying problem.
First you need to copy the file 50-synaptics.conf:
[code]
sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf /usr/share/X11/xorg.conf.d/60-synaptics-userdefined.conf
[/code]
Be careful, that the copied filename should start with a number greater than 50 and should have .conf as file extension. [1] Like in my case: “60-synaptics-userdefined.conf”.
Now edit the new file 60-synaptics-userdefined.conf.
[code]
sudo gedit /usr/share/X11/xorg.conf.d/60-synaptics-userdefined.conf
[/code]
The following setting worked fine for me. The most parts are from Coderspiel [2];
[code]
Section “InputClass”
Identifier “nathan touchpad catchall”
MatchIsTouchpad “on”
MatchDevicePath “/dev/input/event*”
Driver “synaptics”
Option “TapButton3″ “2”
Option “LockedDrags” “1”
Option “FingerLow” “38”
Option “FingerHigh” “43”
Option “PalmDetect” “0”
Option “VertTwoFingerScroll” “1”
Option “VertScrollDelta” “-75″
Option “HorizTwoFingerScroll” “1”
Option “HorizScrollDelta” “-75″
Option “MinSpeed” “1”
Option “MaxSpeed” “1”
Option “AccelerationProfile” “2”
Option “ConstantDeceleration” “4”
EndSection
[/code]
The most interesting options are “FingerLow” and “FingerHigh”.
FingerLow [3]:
When finger pressure drops below this value, the driver counts it as a release. Property: “Synaptics Finger”
FingerHigh [3]:
When finger pressure goes above this value, the driver counts it as a touch. Property: “Synaptics Finger”

Update:
After updating to Ubuntu 14.04 the settings where still working fine.
