Touchpad scroll/zoom gestures not working after Synaptic vulnerability fix

[Mahaflame]

Started using a new HP laptop on Dec 10th 2017 , all mouse gestures like two finger scrolls, zooms, three finger clicks, etc - all worked. Was all excited switching from a old laptop to this with great control.

Below Synaptic vulnerability patch was made available on Dec 12 and I Promptly installed the patch on Dec 14 available below at https://support.hp.com/us-en/document/c05827409 

HP Pavilion 15 Laptop (models 15-cc1XX and 15t-cc100)

19.3.31.31

SP81891

ftp://ftp.hp.com/pub/softpaq/sp81501-82000/sp81891.exe

Now none of the multi-finger gestures work. I go to TouchPad settings and i see synaptic made this touch pad as a simple PS2 pointer device with no settings for gestures.

Hoe do I regain those multi-finger gestures for scroll, zoom, switching windows, etc.

Hi @Mahaflame,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues with the touchpad not working on your HP notebook. Don't worry we'll work together to find a solution for you.

First, restart the computer and tap on F10 during restart, once on BIOS screen, move the mouse cursor around to check if it works normally, 

If it does, it would confirm a software issue and you follow the below steps if it doesn't work on its a hardware failure and I would suggest a touchpad replacement. 

Let's start off by updating the Bios and Chipset drivers on your PC from our HP support website, using this link.

I recommend you to uninstall any generic synaptic drivers showing up for the touchpad (if available) under hidden devices from the device manager: 

• Click Start, point to All Programs, point to Accessories, and then click Command Prompt. 

• At a command prompt, type the following command , and then press ENTER: 

set devmgr_show_nonpresent_devices=1 

• Type the following command a command prompt, and then press ENTER: 

start devmgmt.msc 

• Troubleshoot the devices and drivers in Device Manager. 
  NOTE: Click Show hidden devices on the View menu in Device Manager before you can see devices that are not connected to the computer. 

• When you finish troubleshooting, close Device Manager. 

• Type exit at the command prompt. 
   
  Note that when you close the command prompt window, Window clears the devmgr_show_nonpresent_devices=1 variable that you set in step 2 and prevents ghosted devices from being displayed when you click Show hidden devices. 

And then download a new version of the synaptic drivers using this link: Click here  

Let me know if those steps worked for you.

If they did, that’s awesome!
