Wacom Tablet not detected ubuntu 20.04, HP probook x360 435 G7
I'm using a HP Probook x360 435 G7 Laptop, with ubuntu 20.04 installed on it. Neither the Wacom tablet is detected, nor the stylus.
This is with bluetooth already turned ON:
Here is the output of various commands:
abhijit@abhijit-laptop:~$ dpkg -l | grep wacom

Note that kde_wacom_tablet was installed and tried, and it crashed. It did not detect any tablet.

Solution 1:
It looks like your device uses an ELAN sensor. The libwacom tablet database doesn't include many ELAN sensors, and the GNOME Control Center won't let you configure any devices that aren't in the database. You can follow the wacom-hid-descriptors "contributing" instructions to share information about your system and hope someone can create a tablet definition from the data. They regularly create definitions for Wacom sensors but their developers aren't as familiar with ELAN hardware...
