I'm on Ubuntu 20.04. I got a new XP-Pen Deco01 V2 drawing tablet. It connects fine, but as soon as I try to move the cursor using the drawing pen, the x server crashes.
Any clues as to how to fix this??

UPDATE: Due to the log line
May 28 00:13:39 Lyra /usr/lib/gdm3/gdm-x-session[20807]: (EE) Too many input devices. Ignoring UGTABLET 10 inch PenTablet Pen (0)
After disconnecting the web cam to reduce the number of input devices, it works correctly.
Is there a better way to fix this ?
