[SOLVED] Wacom Tablet Support

Hello, I use Gnome3 and have a new Wacom Bamboo Connect CTL-470/k and cannot get anything to work. I've searched archwiki, ubuntu,and gentoo forums, but nothing works, and I've installed the xf86-input-wacom through the AUR.
It shows that it is plugged in through usb:

lsusb | grep Wacom
Bus 002 Device 003: ID 056a:00dd Wacom Co., Ltd 

and I loaded the driver:

sudo modprobe wacom
lsmod | grep wacom
wacom                  27924  0 
usbcore               120796  6 wacom,uvcvideo,usbhid,uhci_hcd,ehci_hcd

In system settings, under Wacom Graphics Tablet, it says "No tablet detected please plug in or turn on your Wacom tablet." I know this is a new model and is not supported in the kernel, but I can't even get the patches working that others say work fine. I also multi-boot with ubuntu, debian, fedora, and slack. I've tried it on Ubuntu and have the same issue- haven't tried it on the others yet. Any help is greatly appreciated.

Re: [SOLVED] Wacom Tablet Support

Hello Killgriff. I had a similar problem not too long ago. Basically the CTL 470 is a new Wacom tablet that requires drivers that has not been added to the kernel yet (they are expected to be added in v 3.3). Therefore, you must rely on a patched Wacom module. After a couple of hours searching I found a solution that works combining the Arch Wiki Wacom Article and this Ubuntu forum post

First obtain the xf86-input-wacom-git package from the AUR. This will provide the much needed udev rules and X11 configuration options. Next grab the patch from the third post in this thread (it's an attachment), decompress it, then run

make -C /lib/modules/`uname -r`/build/ SUBDIRS=$(pwd) modules

then

depmod -a

and finally copy the kernel module to the tablet drivers directory as such:

cp wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

Afterward you should restart. Once you do check to see if theres a wacom symlink in the /dev/input directory, then cat it move your stylus around and see if it works (there should just be a bunch of random characters when you move it around the tablet).

I will probably work on some AUR package in the near future.

Re: [SOLVED] Wacom Tablet Support

Everything seemed to load properly, but still no symlink.

Re: [SOLVED] Wacom Tablet Support

Everything seemed to load properly, but still no symlink.

In addition to n0dl's excellent instructions (thanks n0dl!) there are two things you need to do to get CTL-470K (Bamboo Connect Pen) working:

Add the following to the '# Type-named links for multiple tablets' section of /etc/udev/rules.d/10-wacom.rule generated by xf86-input-wacom-git:

ATTRS{idVendor}=="056a", ATTRS{idProduct}=="00dd", SYMLINK="input/tablet-bamboo-pen"

And make sure that the wacom.ko you get after the 'make' step supersedes the previous version (back up the old wacom.ko.gz and put the newly-obtained wacom.ko in its place after gzipping it).

Add wacom to the MODULES array in rc.conf and reboot. The tablet should work after this.

Re: [SOLVED] Wacom Tablet Support

I followed all the steps in this post but it did not work for me at first. First off I am using a Lifebook TH700 touchscreen. I am just trying to set up the tablet for my classroom which has an old compaq. When I followed all the steps my touchscreen stopped working and the tablet still did not work. I started to undo all the steps. First I removed the udev rules (rebooted still didn't work), then I reinstalled the kernel. When I rebooted everything was working great. Tomorrow I need to try on my classroom laptop, but not sure what worked. Any thoughts? I will post how things worked out for me.

Re: [SOLVED] Wacom Tablet Support

I used the steps found in this post on the classroom Compaq today, and I still found that I had to reinstall the kernel before it would work. I did not need to install the git version of the driver.

Thank you for sharing this info around.

Re: [SOLVED] Wacom Tablet Support

I've followed the above steps and still can't get this to work. lsusb shows my wacom bamboo pen is detected: -
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 07ab:fcdb Freecom Technologies
Bus 003 Device 002: ID 1c4f:000e SiGma Micro
Bus 003 Device 003: ID 046d:c051 Logitech, Inc. G3 (MX518) Optical Mouse
Bus 004 Device 003: ID 056a:00dd Wacom Co., Ltd

It also appears in lsmod: -
lsmod | grep wacom
wacom                  33718  0
usbcore               146209  7 ehci_hcd,uhci_hcd,usbhid,wacom,uas,usb_storage

I've followed the above article with regards to applying the patched kernel module and added the line for my pen device in the 10-wacom udev file as well but I still don't get any wacom devices listed in /dev/input. Is there anyone else who had this issue and managed to fix it or any further things I could check?

Re: [SOLVED] Wacom Tablet Support

Okay, just to clear this up for anyone because it wasn't clear to me at first (it took a few reboots and head scratching / rereading of this post to actually catch what was going on):

FYI: Please do a pacman -Syu and reboot before you begin this - it's very important. My updated kernel is 3.2.5-1-ARCH.

#1. First check lsusb to see if the Wacom device is being detected:

lsusb | grep Wacom
Bus 002 Device 003: ID 056a:00dd Wacom Co., Ltd 

#2. If it is, obtain xf86-input-wacom-git from the AUR (I used yaourt).

yaourt -S xf86-input-wacom-git

#3. Grab the tablet driver from here, third post down as an attachment (wacom-bamboo.tar.gz):
http://sourceforge.net/mailarchive/foru … om-discuss

#4. Decompress this archive in a directory of your choice.

#5. Change to that directory and run

make -C /lib/modules/`uname -r`/build/ SUBDIRS=$(pwd) modules

#6. Run [as root]

depmod -a

#7. Copy the compiled file to the tablet module's directory:

cp wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

#8. Create a file called 10-wacom.rule under /etc/udev/rules.d/ and place this within it:

ATTRS{idVendor}=="056a", ATTRS{idProduct}=="00dd", SYMLINK="input/tablet-bamboo-pen"

(This was not automatically generated for me on install of any package.)

#9. Under /lib/modules/`uname -r`/kernel/drivers/input/tablet/, backup the original wacom.ko.gz (I renamed it to wacom.ko.gz.backup), and gzip the wacom.ko

gzip wacom.ko

wacom.ko.gz should be in the directory again.

#10. Add wacom to the MODULES area of /etc/rc.conf.

#11. In /etc/X11/xorg.conf I've placed the following. I'm still troubleshooting things, but for the moment (and I literally mean for the moment) this works:

Section "InputDevice"
    Driver        "wacom"
    Identifier    "stylus"
#    Option        "Device"       "/dev/input/wacom-stylus"
    Option "Device" "/dev/input/tablet-bamboo-pen"
    Option        "Type"         "stylus"
    Option        "USB"          "on"                 # USB ONLY
    # Changed to Relative: 02-12 @ 1:10pm
    Option        "Mode"         "Relative"           # other option: "Absolute" Relative
    Option        "Vendor"       "WACOM"
#    Option        "tilt"         "on"  # add this if your tablet supports tilt
#    Option        "Threshold"    "5"   # the official linuxwacom howto advises this line
EndSection

Add to Section "ServerLayout":

	InputDevice "stylus" "SendCoreEvents"

#12. Reboot.

#13. Start X, and it should operate in one of it's modes (tablet or mouse) when you draw on it. It's worth noting here that while the tablet works in KDE, doing a cat /dev/input/tablet-bamboo-pen did nothing from the prompt when using the tablet.

I'm not sure of the tablet's limitations, but it's working for the moment. I don't mean to redo instructions already provided, but I needed something slightly more straightforward, guys.

It's worth noting the way /dev/input/ currently looks using this method:

by-id    event0  event2  event4  event6  event8  js0  mice    mouse1  tablet-bamboo-pen
by-path  event1  event3  event5  event7  event9  js1  mouse0  mouse2

Just for reference, nothing spectacular.

Re: [SOLVED] Wacom Tablet Support

I'm glad you were able to get everything going! Hopefully others will find some help here, too.

I have to wonder Jamiroph and n0dl, anyone else: do you have tablet sensitivity issues as noted in this thread? https://bbs.archlinux.org/viewtopic.php?id=134803

I'm unsure if this is relative to only certain types of tablets, but if you do have these problems, please watch (or join?) the discussion.

** EDIT **: It's also worth noting: if your tablet stops working as a result of a kernel upgrade, it's because the kernel upgrade overwrote the wacom.ko. >.>; Since the wacom.ko has been replaced, those steps need to be performed again.
