Howto fix a too sensitive touchpad on Linux

If your touchpad is too sensitive (meaning the cursor jumps around when you either put your finger on the touchpad or you remove your finger from the touchpad) then here’s how to fix it:

Open a terminal window and find out the ID of the touchpad:

The output should look something like this:

So the touchpad (an Alps in my case) has ID 13.

Now let’s list the properties (settings) of the touchpad:

The output should look something like this:

The setting to look for is “Synaptics Finger”:

The “298” is the ID of the setting and the “12, 15, 0” values represent FingerLow, FingerHigh and FingerPress. You can read about their meaning here

Start increasing the first 2 values each in increments of 2 with the following command. The changes become active immediately. If the touchpad is still too sensitive then keep on increasing those values until the problem is solved.

The syntax of the command is:

In my case the values that solved the problem were:

Once the proper values are found they can be made permanent by adding them to the InputClass of the synaptics config file:

If the problem can not be solved by changing the FingerLow and FingerHigh values then there are a ton of links in Google that discuss this problem. An excellent resource is https://wiki.archlinux.org/index.php/Touchpad_Synaptics
