I have Ubuntu 10.10 Maverick Meerkat installed. The problem is that the tap to click feature on my touchpad is too sensitive in ubuntu. It works fine with windows. I randomly end up clicking things while moving the mouse. Its very irritating. Any solutions ? I have a HP Probook 4410s laptop.

This works for me in Ubuntu 10.10

To see what trackpad you've got and what it's called, try:

xinput list

My device is called "SynPS/2 Synaptics TouchPad"

There are 3 finger pressure settings: low, high & press. See what their current values are with something like:

xinput list-props "SynPS/2 Synaptics TouchPad" |grep -i finger

Change the values with something like:

xinput set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Finger" 50 90 255

By increasing the second parameter, you require more finger pressure for the trackpad to respond. The first parameter controls release pressure, the third is to detect a button press (I think).

This may be silly but do you have gpointing-device-settings installed?

dpkg --get-selections | grep gpointing

Should show it if you do have it installed. If not try installing it with apt-get or aptitude.

For Ubuntu 20, use these instructions based on the Adjust Touchpad Sensitivity section of the SynapticsTouchpad help page.

First, determine the device number, id, of your touchpad device.

xinput list

(Optional but helpful) In a terminal, you can monitor events emitted by that device:

xinput --test <id>

NOTE: While the test is running, you may be unable to select ranges of text in your terminal.

(Optional but helpful) In another terminal, you can monitor for changes in the device properties:

xinput --watch-props <id>

The sensitivity of the touchpad is controlled by the Synaptics Finger properties, three numbers described in the synaptics manpage:

Option "FingerLow" "integer"
       When  finger  pressure  drops  below this value, the driver counts it as a release.
       Property: "Synaptics Finger"

Option "FingerHigh" "integer"
       When finger pressure goes above this value,  the  driver  counts  it  as  a  touch.
       Property: "Synaptics Finger"


Option "FingerPress" "integer"
       When  finger  pressure  goes  above  this  value,  the driver counts it as a press.
       Currently a press is equivalent to putting the  touchpad  in  trackstick  emulation
       mode. Property: "Synaptics Finger"

Use xinput --set-prop to set these values:

xinput --set-prop <id> "Synaptics Finger" 50, 80, 255

You may have to play with the values to find your preferred thresholds. When you change them, you should see the change reflected in the --watch-props terminal.
