Ubuntu – 14.04 Touchpad is too sensitive


My touchpad is way too sensitive. While writing, the cursor jumps suddenly to the place the mouse cursor is sitting. I am not even touching the touchpad! I had the same problem with 12.04 and recently did an upgrade to 14.04, which didn't solve the problem.

In the mouse-and-touchpad settings, there are only settings for a mouse, not a touchpad. I have tried this:

sudo apt-get install gsynaptics


which didn't help.

Then I found this which might describe my problem.

But I get stuck halfway through. When putting this in the terminal:

(Add the patch to the psmouse module:)

sudo dkms add -m psmouse -v elantech-v6

I get this:

Error! Could not find module source directory.
Directory: /usr/src/psmouse-elantech-v6 does not exist.

Can anyone help?

Best Answer

xinput list

will give your device name (look for TouchPad)

xinput list-props "Touchpad Name"

This will give the available properties of your touchpad. You will probably find that the property is still "Synaptics ..." based, which means that you would type something like:

xinput set-prop "Touchpad Name" "Synaptics Finger" 50 90 255

I use the following properties (replace Touchpad Name with yours from the xinput list command) for mine to reduce the overall sensitivity:

xinput set-prop "Touchpad Name" "Synaptics Noise Cancellation" 20 20
xinput set-prop "Touchpad Name" "Synaptics Finger" 50 90 255

The above 2 commands seem to do the trick for me. Before them my touchpad was basically unusable.
