As per https://help.ubuntu.com/community/SynapticsTouchpad
You can determine your input devices (not just touchpad), by using the command
From Terminal Using
First you want to see what number your device is labelled as. Use the command
xinput list to see all of your devices. (You could probably shorten this to a command like
xinput list |grep Synaptic -n2, or something similar)
Note the id next to the Device.
- Determine your current settings by doing the command
xinput --watch-props YOURDEVICEID (YOURDEVICEID being the device id you noted in previous step)
- You may wish to adjust sensitivity which is Synaptics Finger, but it is dependent on your actual touchpad. So you may have to tweak other ones as well. (Press Ctrl+C to exit).
- Once you determine what you want to change you will input it with the
xinput with the
Same Example as from top source below
xinput --set-prop YOURDEVICEID "Synaptics Finger" 50 80 257
This will adjust the sensitivity of the pad in general.
From Terminal using
You can also find a configuration with
- Input the command
synclient -l to view your current configuration. (You can also redirect this into an editable document if you want to manipulate it further with a command such as
synclient -l > touchpadconfig)
- You can set the value by doing a command like
synclient LeftEdge=130 to set left edge of the touchpad to a coordinate 130.
Unfortunately there are lot of settings which can be adjusted, and you may need to adjust them yourself. However the
man synaptics explains each of the parameters which can be set in fairly human readable terms.
