I was working on a ZBook G3 the other day and ran into an infuriating issue with its Synaptics Touch Pad: The touch sensitivity out-of-the-box was set so high that when I slowly moved the cursor it would get jittery and not respond.
While examining specific trackpad details, I found that I have a Synaptics LuxPad V1.3 device that communicates using an SMB port (whatever that is!)
In investigating this further I found that the Synaptics driver hides the 'advanced settings' from windows 10 users for some inexplicable reason. Once enabled I was able to fine-tune the trackpad settings to be more bearable.
How to Enable Synaptics Settings
Note: Registry usage can be harmful- be sure you have all appropriate backups before continuing!
- Open regedit.exe
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl
- Open the HideTPSettings DWORD Value
- Change the value from 1 to 0 and hit OK
Use the Advanced Settings
- Open Start -> Settings
- Select Devices
- Click on Mouse and Touchpad in the left-hand bar
- Scroll to the bottom of the window
- Click on Additional Mouse Options
- Select the TouchPad tab
- Click the Settings... button
Within this UI you can adjust your trackpad to a greater degree of precision than you can using the built-in windows tools.
