The "stylus not recognized" part of this issue is almost certainly https://bugzilla.gnome.org/show_bug.cgi?id=793499.
No access to the pad device on the other hand is not an issue I'm familiar with. The old unity-control-center bug that OP linked do was due to an issue with GNOME not being compatible with tablets whose pens don't have an eraser. That issue was fixed in GNOME 3.16, however, and shouldn't be present in the current version of the gnome-control-center. I do see a reference to somebody else having similar pad issues upstream at https://bugzilla.gnome.org/show_bug.cgi?id=789287 but it doesn't look like anyone has begun to dig into the bug. My own (Arch Linux) system doesn't exhibit the pad issue with an Intuos Art Medium (CTH-690) and GNOME 3.26, for what its worth. **** linuxcub: You should have both a "Stylus" and "Tablet" button at the top of the Wacom control panel, next to "Test your Settings". The "Stylus" button shows "Stylus not Recognized", but what message appears when the "Tablet" button is pressed? Or are the buttons missing? That might give a place to start digging... ** Bug watch added: GNOME Bug Tracker #793499 https://bugzilla.gnome.org/show_bug.cgi?id=793499 ** Bug watch added: GNOME Bug Tracker #789287 https://bugzilla.gnome.org/show_bug.cgi?id=789287 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1753525 Title: Wacom tablet not recognized in Settings > Devices Status in gnome-control-center package in Ubuntu: New Bug description: 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 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 :( Hopefully this will be resolved till the final version of 18.04 in April?
