Linux Wacom Tablet Project / Bugs / #313 Tablet is invisibe for xsetwacom

Jason Gerecke - 2016-03-21

Could you let us know what model of tablet you have? It would be helpful to see the output of lsusb, and xinput list if possible.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Intuos Pro S

After Ubuntu upgrade I removed manually installed drivers input-wacom, libwacom and xf86-input-wacom with 'make uninstall'. And reinstalled packets from repository.

Outputs:

My guess would be that the xf86-input-wacom driver wasn't installed correctly for some reason. Could you please attach your Xorg.0.log for review? It can be found in several locations; try looking for /var/log/Xorg.0.log, ~/.local/share/xorg/Xorg.0.log, or the output of the following
command: journalctl _COMM=Xorg _COMM=Xorg.bin _COMM=gdm-x-session -b0

Is xserver-xorg-input-wacom (from ubuntu repository) == xf86-input-wacom from sf?

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Anton Burkun - 2016-03-23

Hmm.. I'm sorry, but fixed.
I had removed xserver-xorg-input-wacom + its dependent xserver-xorg-input-all (metapackage).
After that I installed xserver-xorg-input-wacom again (without ...-input-all).
now:
~$ xsetwacom --list devices
Wacom Intuos Pro S (WL) Pen stylus id: 12 type: STYLUS
Wacom Intuos Pro S (WL) Pen eraser id: 13 type: ERASER
Wacom Intuos Pro S (WL) Pen cursor id: 14 type: CURSOR
Wacom Intuos Pro S (WL) Pad pad id: 15 type: PAD
Wacom Intuos Pro S (WL) Finger touch id: 16 type: TOUCH

All ok!

Not all ok. 'Wacom Tablet' page in settings is empty now.

Also now led file path is not:

/sys/bus/usb/devices/*/wacom_led/status_led0_select

it became (WL):
/sys/bus/usb/devices/*/0003:056A:0084.000C/driver/0003:056A:0084.000B/wacom_led/status_led0_select

or (if via USB)
/sys/bus/usb/devices/*/0003:056A:0314.????/wacom_led/status_led0_select

???? - changed on each reconnect

For the 'Wacom Tablet' settings page to work correctly, you will need to ensure that the Ubuntu packages 'libwacom2' and 'libwacom-common' are installed. If they are, you should see /usr/lib/x86_64-linux-gnu/libwacom.so on your system, as well as a /usr/share/libwacom directory filled with ".tablet" files (the "intuos-pro-s.tablet" file describes your particular device to the system).

As for the sysfs path, I would suggest /sys/bus/hid/devices/*/wacom_led/status_led0_select rather than the "usb" path you're using. There's unfortunately no way to predict the "????" component beforehand, since the kernel generates it whenever the device is plugged in (to support concurrent devices with the same "bus:vid:pid" triple). In theory you could monitor udev for connect events, but that's a little overkill unless you're looking to write your own control panel.

Thank you for path to status_led0_select!

There are just libwacom.so.2.4.5 and @libwacom.so.2
I cannot remove libwacom2 package - ubuntu propose to remove too much packages with it. Try to reinstall without result

Apologies -- libwacom.so.2.4.5 and libwacom.so.2 are indeed expected to be there (the vanilla libwacom.so file is installed by the 'libwacom-dev' package).

Do you see a /usr/share/libwacom/intuos-pro-s.tablet file on your system? If not, that indicates the 'libwacom-common' package is missing. If, on the other hand, you do have the file, then something else is going wrong.

Try opening a terminal and then running the following command: G_MESSAGES_DEBUG=all unity-control-center (or perhaps G_MESSAGES_DEBUG=all gnome-control-center if you aren't using Unity) Afterwards, open the Wacom panel and copy/paste all the terminal output into a reply. Also, after doing that, run the command sudo journalctl -b0 _EXE=/usr/lib/gnome-session/gnome-session-binary | grep settings-daemon and copy/paste the output into a reply as well.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

First output is:

(unity-control-center:18210): wacom-cc-panel-WARNING **: Failed to create fallback wacom device for '/dev/input/event15': db is NULL (3)

(unity-control-center:18210): wacom-cc-panel-WARNING **: Failed to create fallback wacom device for '/dev/input/event13': db is NULL (3)

(unity-control-center:18210): wacom-cc-panel-WARNING **: Failed to create fallback wacom device for '/dev/input/event14': db is NULL (3)

And second command output is empty.

And I see file /usr/share/libwacom/intuos-pro-s.tablet

Based on the db is NULL warnings being produced, it looks like libinput is having trouble loading its database. The files clearly exist in the right spot, so that's not the issue. The other possibilities are that (1) libwacom is looking in the wrong folder, (2) that the stylus file is missing/empty, or (3) that the database contains duplicate entries.

Did you try installing libwacom from source (instead of from apt-get) at some point in the past? If so, the build might have been misconfigured -- check if a /usr/local/share/libwacom directory exists.

Let me know if you see a file named /usr/share/libwacom/libwacom.stylus and verify that it contains data.

Run apt-get install libwacom-bin and then (with your tablet plugged in) run libwacom-list-local-devices. Let me know what output is printed out.

Thank you for responses!

1) yes, I had build them from sources for ubuntu 14.04 and kernel 3.13. Now I have empty dirs: /usr/local/share/libwacom and /usr/local/share/libwacom/layouts

2) yes, exists with data

3) $ libwacom-list-local-devices
Failed to initialize device database

The presence of /usr/local/share/libwacom makes me wonder if the libwacom libraries and binaries are still lurking on your system and applications are being tricked into using them.

1) Please run which libwacom-list-local-devices and let me know the result.
2) Check if /usr/local/bin/libwacom-list-local-devices or /usr/local/lib/libwacom.so*exists.
3) Try running libwacom-list-local-devices --database /usr/share/libwacom with your tablet plugged in.

Hello!

1)~$ which libwacom-list-local-devices
/usr/bin/libwacom-list-local-devices

2)~$ cd /usr/local/lib/
/usr/local/lib$ ls
libvidstab.so libvidstab.so.1.0 libwacom.so.2 libwacom.so.2.2.1

~$ cd /usr/local/bin
/usr/local/bin$ ls
(no libwacom-list-local-devices)

3) $ libwacom-list-local-devices --database /usr/share/libwacom
**
libwacom:ERROR:libwacom-database.c:114:bus_to_str: code should not be reached

Shold I remove /usr/local/lib/libwacom.so* files?

UPD
removed files. and now seems ok:
$ libwacom-list-local-devices --database /usr/share/libwacom
[Device]
Name=Wacom Intuos Pro S
DeviceMatch=usb:056a:0314;

Also Config Panel Applet now displays information. Thank you!

On-Screen Help and key bindings are not working))

during setting keybinding via control panel I got this log:

Glad to hear that removing those files seems to have fixed the issue :) As for the on-screen help and key bindings not working properly, could you please open a new bug with the necessary details? It really makes things a lot easier for us to manage.
