Hi,

I'm using GuixSD v0.10.0 with GNOME.  I have a Wacom tablet.  When I
plug it in, activity in dmesg suggests the tablet is successfully
discovered, and I can move the mouse and click using the stylus, which
is nice, but it's jittery and I can't configure it.  When I click on
"Wacom Tablet" in the GNOME settings, I get the following error:

No tablet detected
Please plug in or turn on your Wacom tablet

I thought maybe the problem was that I was missing necessary packages.
However, the "gnome" package is installed globally, and I see that its
dependencies include both libwacom and xf86-input-wacom.  Just to be
extra certain, I tried installing those two packages in my user profile,
and rebooted, but the result remained the same.

Is there something else I have to do to enable "Wacom Tablet" in the
GNOME settings?  I feel like I'm missing something simple.
