    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    Correct. Your model is in xf86-input-wacom if you cloned the git.

    Check in Synaptic Package Manager, or whatever, and make sure you didn't uninstall xserver-xorg-input-all somewhere along the way. Say by doing an uninstall of xserver-xorg-input-wacom. Also did you install a dkms version of wacom.ko at any point?

    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    I have both installed, I just tried uninstalling xserver-xorg-input-wacom and it uninstalled xserver-xorg-input-all. I then tried reinstalling xserver-xorg-input-all but it insists on installing xserver-xorg-input-wacom along with it. No wacom dkms package was installed.

    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    Oops! That's what I meant. There's a new dependency between the two since Karmic. As far as I can tell that's due to a packaging issue and not any real need to have it that way. I could be wrong.

    Well recloning the git was going to be the next step anyway. Before you do that check Troubleshooting and make sure your system doesn't require the 64-bit flag for both or a different kernel header for the linuxwacom wacom.ko.

    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    I'm a bit confused...should xserver-xorg-input-wacom and xserver-xorg-input-all be installed or uninstalled?

    I'll try recloning the git...

    BTW, the Ubuntu I have installed has RTAI installed (it's from http://www.linuxcnc.org/content/view/21/4/). Would this make a difference?

    Also, I'm not actually using the Wacom as a tablet or anything, really I just need to get the coordinates of the pen programmatically, the pointer doesn't have to actually move. Is there API for doing this I could look into? Can I read from some file in /dev ?

    Thanks!

    Sorry, they should be installed before you clone the git. You need xserver-xorg-input-all for xf86-input-wacom to work. This does mean there is a chance of version conflict, but we can't use the old purge routines for the above mentioned reasons.

    Well that's great, I'm looking at the RTAI 3.4 User Manual rev 0.3, and I don't see a definition of RTAI in the first few pages. Real Time something Interrupt?

    OK, what kernel is that. If we ask:
    Code:
    uname -r
    is it going to tell us the truth or is it patched so it will mislead us?

    We've already got the values from Xorg.0.log but they're wrong:
    Code:
    (II) XINPUT: Adding extended input device "Wacom Bamboo Comic 2FG Pen stylus" (type: STYLUS)
    (--) Wacom Bamboo Comic 2FG Pen stylus: top X=0 top Y=0 bottom X=-2147483648 bottom Y=13530 resol X=100000 resol Y=100000
    You can also get them by entering:
    Code:
    xinput list-props "device name"
    There will be a line like:
    Code:
      Wacom Tablet Area (270):	0, 0, 14720, 9200
    Someone else was also reporting nonsense coordinates in the last little while. I can't remember what the problem was right now.

    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    Well I didn't touch the computer for 5 days and when I came back, the stylus works! Not sure what happened. But the computer I got it to work on (#2) isn't the one I really need the Wacom installed on (#1), I just tried installing it on it because I was getting frustrated with it not working on the first computer.

    Both computers are running Lucid and RTAI (so it's not the fault of RTAI) and I followed the same installation instructions for both. The first computer's cursor is having the same problem that the second computer used to have. I noticed on the computer where the wacom works, cat /dev/input/event5 fills the screen with stuff, while the same command on the first computer returns nothing. So I guess we can conclude that it's something with linuxwacom, not xf86-input-wacom.

    Weird. Any ideas?

    Thanks!

    Nope. Definitely weird.

    Isn't that always the way?

    You've ruled out a Lucid RTAI problem, which is progress.

    About the only reason I can come up with no raw data coming in over the device input event is a usb problem. Maybe the wacom.ko, maybe a loose connection or underpowered usb port. I think a 1.1 works and it doesn't have to be 2.0. Did you try another port? Hard to believe something's wrong with the one machines linux usb stack.

    Smile Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    Hi, all I've been through just about all the threads on ubuntuforums on this subject and haven't found an end-to-end troubleshooting tutorial/hint. Hopefully this post and replies will fill the gap since this thread and the backports fixed were the most promising.

    I have xf86-input-wacom installed, and I've installed the current(2.6.35.27.35) linux-backports-modules-input-maverick-generic (per bhttps://launchpad.net/bugs/527912 and kernel from maverick-proposed with the corresponding kernel. I also found some regressions with later bug numbers that are marked as fixed, but they do not seem relevant. Before finding the backports I cloned,auto-configured, make'd, make install'd the git repository, downloaded and built the tarball etc, used several recommended ppas all to no affect (nothing has changed w/regards to the kernel detecting the device).

    I believe that the problem is that the kernel driver simply is not detecting my tablet. I'm hoping for a lower diagnostic to understand what is wrong (e.g did I leave some remnant from an older attempt somewhere that is conflicting?).

    As far as I can tell, everything is good so far (the USB protocols are working and the tablet identifies itself). The next place is where I thing the problem as per this debugging hint on sourceforge. From this output I conclude that the kernel is not recognizing my device.

    Re: HOW TO Set Up the Bamboo Pen & Touch in Lucid

    Hi Derek Day,

    OK, I think I followed all that.

    You have the 00d8, or Bamboo Comic Medium (CTH661/S1; Product ID = 0xd8 ). Released 10/2010, which is the problem.

    You have a recent git clone of xf86-input-wacom ~0.10.11. So you're good there as the last of my patches for the 5 new BambooPTs were committed a few weeks ago.

    It looks like the back ported module wacom.ko does not have your model, as far as I can tell. Your choices are to manually patch the linuxwacom 0.8.8-10 wacom_wac.c with your model, described in post #2 on this thread, or install input-wacom-0.10.10-2. I'd go with input-wacom. Instructions are in the alternate section 2 of the linuwacom HOW TO. That's of course if you can not wait for Natty with kernel 2.6.38, which I'm pretty sure has your model.

    Thanks, Favux.

    I went through a little frustration here until I figured out your instructions better. I believe you meant to say Alternate Section *1* because then the rest of your advice matches up. I'll leave the narrative here in case it helps others.
    ================================================== ======
    Since I'm on a 64 bit kernel so I have been adding the extra libdir option per the comments on source forge. Your comment here in Section 2, led me to remove this.

    dday@gandalf:/usr/src/xf86-input-wacom$ locate evdev_drv.so
    /usr/lib/xorg/modules/input/evdev_drv.so

    I also seem to have gotten a lot more updates with the manual dependency install vs the build-dep. I am not sure whether that is a result of updating my kernel when I switched to maverick-proposed or if I missed something.

    So I was excited to run the build, thinking I'd finally get my own wacom.ko, however there is no wakom.ko built.
    ================================================== ======

    Then I figured out that I was reading Section 2, and realized there was a distinction between xf86-input-wacom and input-wacom -- so I went back to alternate section 1 -- not only did the rest of your advice make more sense, but it successfully generated a wacom.ko, so now I will reboot and see what happens. I will update this post as soon as I know.

    UPDATE: After rebooting, dmesg and /proc/bus/input/devices still show that my tablet is not recognized. I will take a look at the source file you referenced, make sure my device id is there, and see if I can update the output in dmesg when the module is loaded -- as a sanity check to make sure I've copied the right files, and the right files are being built. Is there any other debugging I can do to see what calls are being made when I plug in the USB cable? I think I'd also be fine with moving to Natty early if that is my best option.

    Thanks,
    Derek
