Wacom CTH-450/K Intuos Art Black Pen & Touch S; stylus not recognized

I have the same problem with Ubuntu 18.04 developing branch as described for Ubuntu 16.04 in https://bugs.launchpad.net/ubuntu/+source/unity-control-center/+bug/1575887 I can draw, e.g., with tuxpaint, I can use stylus and graphic tablet "Wacom CTH-450/K Intuos Art Black Pen + Touch S" like a touchpad with mouse (left, muddle, right button), but I cannot access the pad via Settings > Devices > Wacom Tablet: "Stylus not recognized". So, no reprogramming of stylus buttons and tablet buttons :( See https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1753525 For more details ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: gnome-control-center 1:3.26.2-0ubuntu5 ProcVersionSignature: Ubuntu 4.15.0-10.11-generic 4.15.3 Uname: Linux 4.15.0-10-generic x86_64 ApportVersion: 2.20.8-0ubuntu10 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Mar 5 16:48:48 2018 ExecutablePath: /usr/bin/gnome-control-center InstallationDate: Installed on 2018-03-05 (0 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180304) SourcePackage: gnome-control-center My solution so far: sudo apt update sudo apt install ubuntu-gnome-desktop sudo apt install --reinstall gnome-control-center Reboot, login into 'Gnome on xorg', Wacom now programmable with Settings > Devices > Wacom Tablet Log out, login on 'Ubuntu', now Ubuntu does it too
As you say in https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1753525/comments/13 , if the "GNOME on Xorg" session works (with gnome-control-center as per upstream), this is not a GNOME issue. AFAIU the ubuntu session uses unity-control-center and not gnome-control-center. If it is unable to recognize the stylus, the culprit is probably there.
Thank you and sorry, but I was referred to your site by https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1753525/comments/12
Carlos, the Ubuntu session in 17.10 is GNOME on Wayland with a few tweaks. It's the same in 18.04 except it uses X instead of Wayland. Ubuntu uses gnome-control-center now. (unity-control-center is still used by Unity but Unity is not the default in the newest Ubuntu releases.)
I stand corrected. Feel free to reopen if you are confident this is a wayland vs xorg issue. Bug #793499 sounds similar, but that doesn't seem too related to windowing.
