Wacom tablet not recognized in Settings > Devices

[linuxcub]

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?

My solution, sort of:

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 :)

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...

> You should have both a "Stylus" and "Tablet" button at the top of the Wacom control panel

No, I don't! My Wacom looks like this
http://101.wacom.com/UserHelp/en/TOC/CTL-4100wl.html

"About Wacom Intuos"

" >> Assign Settings in Wacom Tablet Properties" shows the stylus with its two buttons

The tablet has 4 buttons, at each top corner, two on the left, two on the right. If I press one of teh bottons, a menu appears, like "Show onscreen help, assign keystroke, etc."

I'll attach screenshots from my Ubuntu with the next post.

Here are the screenshots from my Ubuntu 18.04:

Keep in mind, this all fuctioned only after I had my Bionic gnome-ized as described.

Ok, bye for now

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

@Sebastien Bacher:

Please help! At https://bugzilla.gnome.org/enter_bug.cgi I am presented with these options to start with:
----------------------------------------------
 All: Show all products

Bindings: Bindings part of the GNOME 3 set (C++, Java, Javascript, Perl, Python, etc)
Core: Core Desktop functionality software part of the GNOME 3 set
Platform: Low-level software part of the GNOME 3 set (Platform and Extended Platform)
Infrastructure: Infrastructure related queries (servers, services hosted, websites, Bugzilla, release engineering)
Applications: Applications that are not part of GNOME 3 Core or GNOME 3 (Extended) Platform
Other: Other software not covered by the other classifications
Deprecated: Deprecated and unmaintained software
----------------------------------------------

Which option should I choose in my case? I am completely helpless! I never used this website before!

Thanks,

linuxcub

Edit: to be more precise on my tablet:

"Wacom CTH-450/K Intuos Art Black Pen & Touch S"

[Sebastien Bacher (seb128)]

You can use that url directly https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-control-center

[linuxcub (smusnmr)]

Here is the link: https://bugzilla.gnome.org/show_bug.cgi?id=794159

However, is it really a Gnome bug? After all, after I installed ubuntu-gnome-desktop it was ok. Sounds, like the missing ubuntu-gnome-desktop did it, didn't it?

[linuxcub (smusnmr)]

It is not a Gnome issue, it is an Ubuntu issue: https://bugzilla.gnome.org/show_bug.cgi?id=794159#c1

[linuxcub (smusnmr)]

Usually I use my Wacom Intuos CTH-450/K with Gimp. Now I tested it with Krita. Seems that all functions of the board are supported, including varying line width with varying stylus pressure. But only after I installed gnome, see above https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1753525/comments/2
This will still give the developers something to work till April.

[linuxcub (smusnmr)]

Correction: my graphics tablet is a > CTH-490/K <

[Jason Gerecke (killertofu)]

linuxcub, my apologies for not replying sooner -- I don't think I got a notification of your messages for some reason...

Its odd that installing/reinstalling portions of Ubuntu seem to fix the issue. It looks like the Bionic beta only relased IOSs for Kubuntu, Budgie, Kylin, MATE, and Xubuntu. I wonder if their GNOME flavor is still in development and was updated to a broken version when you installed. Force-installing the ubuntu-gnome-desktop and gnome-control-center packages may have brought down a fixed version? Without an official GNOME ISO for me to test, it'll be hard for me to replicate your issue to see if its still present.

Status changed to 'Confirmed' because the bug affects multiple users.

The Wacom Intuos S Tablet (Model: ctl 4100) is not recognised in the wacom section in the control center, though basic mouse functionality works.

[Carsten Aevermann (4-carsten)]

Same with me, on two different CPUs (old 2009 macbook and an amd desktop) both running 18.04.

Linux MyCPU 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Also tried the reinstall thingy as suggested in post#2 with no difference.
