Public bug reported:
Errors visible in /var/log/Xorg.0.log. You can see the devices get
disconnected once the pen enters the proximity of the screen (hover
cursor). Uploaded example shows:
[ 15.106] (II) config/udev: Adding input device Wacom HID 516B Finger
(/dev/input/mouse3)
[ 15.106] (II) No input driver specified, ignoring this device.
Reverting to 5.8.0-44-generic fixed this issue.
It is worth noting that the touch is an easy thing to miss when you
don't own a Wacom pen or charged AAAA battery because the touch does not
break until you whip out the pen.
