#320 gnome-properties doesn't detect the wacom intuos PT S

[Ivan RM]

Hi, i found that in any distro in linux the Intuos PT S the gnome wacom properties and the kde properties don't found the tablet, always show that there's not a tablet connected while the tablet is connected.
Other problem is that i can't configure the express keys, only the first key is configurable, the rest isn't detected.

You'll need at least libwacom 0.16 for the tablet to show up properly in the GNOME Control Center. Ubuntu 16.04 and Fedora 23 appear to both meet these requirements (Debian Jessie and openSUSE 42.1, however, do not). Which specific distribution were you trying to use it with?

Also, how are you trying to configure the ExpressKeys? The button numbering is a little weird for this device, so if you use xsetwacom you'll need to run commands like:

$ xsetwacom set <id> button 1 <action>
$ xsetwacom set <id> button 3 <action>
$ xsetwacom set <id> button 8 <action>
$ xsetwacom set <id> button 9 <action>

If you're using the GNOME Control Center, it is not compatible with the default button mapping and you'll have to modify it before it works properly (see bugs [#244], [#266], and [#268] for more information). The easiest workaround is to use the script on my GitHub at https://gist.github.com/jigpu/fde784840ba5731726e7382952b0d5ed -- read the notes at the beginning of the file and then run it :)

lel the commands that i used to set the express keys was incorrect, thanks a lot for this commands it worked, but the gnome-properties still not working.

This is a picture with a example of my situation.

I've taken a closer look into this and was indeed able to replicate the issue. It looks like this issue was already reported as GNOME bug #746117 which was fixed in gnome-control-center commit 66cb45b and released as part of GNOME 3.16.

Basically, versions of gnome-control-center prior to 3.16 will refuse to show a tablet in the Wacom panel if it does not have the eraser. This is a problem for the current generation of Intuos devices ("Intuos Draw" and "Intuos Art"; models CTL-490, CTH-490, CTL-690, CTH-690) since they are eraserless.

The unity-control-center in Ubuntu 16.04 (which is based on an early version of gnome-control-center) appears to not have this patch in place, which is the cause of the issue. Someone else has already reported this bug to Ubuntu as Launchpad bug #1575887 -- I would recommend subscribing to that bug and potentially getting in touch with Ubuntu developers to see what can be done. The issue could potentially be hacked around (if the Ubuntu developers do not want to update unity-control-center) by modifying our driver to always create an eraser, but we'd rather not maintain such a change ourselves.

I tried with the latest version of Antergos, with gnome 3.20...still not working.

I've just tried to replicate the issue under Antegros but don't seem to be getting the same results.

I downloaded antergos-2016.06.14-x86_64.iso and installed it with the GNOME desktop to a VM for testing. After rebooting into the fresh install it appeared that our X driver wasn't installed, so I had to run sudo pacman -S xf86-input-wacom and then logout/login. Afterwards, I opened the Wacom Tabet panel of the GNOME Control Center and was able to see the Intuos Pen small that I have.

I suppose there's a chance that there's an issue specific to the "Pen & Touch" version (as opposed to my "Pen" version), but its pretty unlikely.

Could you please run both lsusb -d 056a: and libwacom-list-local-devices for me, copy/pasting their output into your reply? Also, please attach your /var/log/Xorg.0.log file for review.

It worked in antergos :D!!!!
But...the wacom expresskeys mapping works wrong.

As you see can see in the pic for some reason i can use the 3 key.and the mapping options are wrong.
And i tried to use the left handed option and the drawing space inverted. I'm left-handed and this doesn't help me...i don't now if is a bug or if don't now how to use this xP
I hope that canonical fix the problem in ubuntu.

[Jason Gerecke]

Ah, good to hear that you managed to get Antegros working for you :)

The ExpressKey issue is a known bug, but there is a workaround that should get things working properly.

It sounds like the "left-handed" option is working properly, but probably shouldn't be available for your particular tablet. Its intended to only show up for tablets like the Intuos Pro or some of the "Bamboo" tablets which have their ExpressKeys along the left side (making them awkward to use left-handed). The option lets you use the tablet rotated 180 degrees, placing the ExpressKeys under your right hand instead. For devices like yours with the buttons along the top, it doesn't make much sense to rotate the tablet 180 degrees since it wouldn't make accessing the ExpressKeys any easier.

Let me know if the workaround works for you and I'll close this bug again (I too hope Canonical tackles that bug -- I'm sure many others will find themselves in this same situation).

[Ivan RM]

well i tried the script and didn't worked, in fact the buttons didn't work after the run of the script. This in ubuntu, i don't now in antergos, my live version becomes crazy and crashes when i logout.

[Ivan RM]

The script works well on antergos :), i hope that canonical fix the bug soon.
I suppose that you can close the bug now.
Thanks for the help

Thanks for testing -- its Ubuntu's move now.
