Bug Description

If I make a fresh 20.04 install from scratch, with the default gnome desktop, then plugging the wacom tablet below does not disturb the background, color scheme and keyboard shortcuts, like ctrl+alt+T give a terminal.

But as soon as I upgrade this install with ubuntu-unity-desktop, and I switch to use the corresponding LightDM, then the "system setting" (in the upper right corner) is not able to handle the background (to set it to a solid color, or a photo, it remains solid black), it is not able to set the theme from the default dark to the lighter "radiance", and the worst of all: the former keyboard bindings, like "ctrl+alt+T gives a terminal" are no longer executed, they are still there in the listing, we can change to what keystroke is e browser or a terminal is bind, but will not work if I press the usual combination.

However, the tablet itself works immediately like a dumb mouse device.

This tablet is according to lspci: ID 056a:0378 Wacom Co., Ltd CTL-6100WL [Intuos BT (M)]

Somehow plugging the Wacom to USB disables, paralyses a nice diverse selection of features, but only in the case of Unity, and NOT in the case of the default Gnome.

If Wacom is plugged, then neither "the text entry / switch input source" works, even if I want to switch the input source by mouse in the upper right corner.

If Wacom is plugged, then neither the settings / wacom tab comes up, but if the Wacom tablet is NOT plugged, then the settings / wacom tab comes up and reports that currently no Wacom device is connected.

Unity shell is essentially disturbed with the Wacom tablet mentioned above, while Gnome shell works well.
