Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

1. Press Windows Key + X to open Win + X menu and select Control Panel from the list.
2. When Control Panel opens, go to Hardware and Soundsection and select Mouse.
3. When Mouse settings window opens, you should see ELANor Device Settings tab. Switch to it.
4. Locate Disable internal pointing device when external USB pointing device is attached option and enable it.
5. Click Apply and OK to save changes.

If that doesn't work or isn't available, a registry edit should be the solution for us, I'd personally suggest a registry backup by clicking on file and export before performing the below steps, to be on a safer side:

1. Open Registry Editor and go to HKEY_CURRENT_USER/Software/Elantech/Othersetting/DisableWhenDetectUSBMousekey in the left pane.
2. Change the value from 0 to 1 and close Registry Editor.

After making those changes your touchpad will now be disabled  

Hope this helps! Keep me posted for further assistance.

Hello Echo_lake

Well the issue I have is not on Windows and I do not want to disable the mouse, My issue is on Ubuntu Linux and I want the touchpad enabled there, the problem is that Linux is not even recognizing the touchpad at all:
These is the list of devices that are recognized by linux:

 As you can see there are no ELAN or touch devices recognized there.

Is there a way to at least get it recognized first?
