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?
