Oops, try /dev/input/event[whatever the event number is], maybe it work with symbolic links (like [hid]).  I don't have an ubuntu machine around, so I can only give suggestions, but you'll find a ton of posts about this topic in pd and linuxwacom mailing lists.

You are probably having the same problems that I was having before I purged my system of udev/hal.

I agree, getting a tablet to work properly in pd has become a pain (worse in OS X and windows), but once you do, it makes for a great and cheap controller. 
Arg.. there was one post that I followed exactly on the ubuntu forums on how to get rid of hal, but I can't find it :(  But, maybe this isn't the best way anymore, maybe they got things working correctly. The linuxwacom list is really helpful and always got me on the right track (since the problems were changing as rapidly as Ubuntu).

hello,
i'm running the last ubuntu (9.10), using kernel 2.6.31

hum, i don' really want to spend lot's of time tweaking stuff. it is sad to realize that using a wacom use to be very easy but it is no more...

sudo wacdump /dev/input/wacom gives me a segmentation fault...

thanks for your help

What distribution are you running?  In the newer Ubuntu's (ex Jaunty), I had to do all sorts of things to get back the old (and working) xorg configuration and stop using udev.  I have a ton of posts about this on the linuxwacom-discuss mailing list and probably this one too, I think I was having the same problems as you were then, and finally got it fixed (right before my laptop was stolen and I bought a macbook :).  It may work better now, probably with more tweaking, as that was 1/2 a year ago.


One thing to try; do you get any tablet data output using wacdump?

Good luck getting it working, I'll try to help more if I can.

   argggh.
   your are right : pd did not have permission to read the input device.

   starting pd as root help a bit : now both linuxevent and hid can
   open the device.
   but they does not send any data...



   thanks

       Does pd have permissions to open /dev/input/wacom (or any of the

              The problem that I had with /dev/input/even* devices is
       that it
              always changes when you unplug/replug your tablet.
               /dev/input/wacom is a symbolic link to the newly created
       input,
              no matter what event* it is.

        Try using an

                     hello

                     few years go, i used a wacom with the [gemtablet]
       object.
              this
                     was working perfectly.
                     but i now realize that this object is no more part
       of Gem
              (since
                     3 years).
                     the dummy object that replace it say that one must use
              hid instead.
                     so did i.

                     but i failed making it work.

                     i'm using linux and hid from pd svn.

                     i send a "open /dev/input/wacom" message to the hid
              object, and
                     get as only answer : info: open 0
                     info: device 0

                     if i start pooling, then the wacom did not work
       anymore,
              and i
                     have to reboot the computer to make it work again.

                     playing a bit more with that object made pd to crash.

                     any suggestion to make my wacom work with hid?
                     any other object that could get data from a wacom?
                     or should i try to get the old sources of gemtablet to
              compile
                     again???

                     thanks
