I think that xorg/Debian/Ubuntu has tightened up the security on input
devices to make it hard to log keystrokes, etc. That's my guess about
why they are making it hard. I am sure once someone nails down how
to work around it, it would be once again easy to allow Pd to get data
from HIDs.

thanks for the sugestion, using event[number] is exactly the same

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). Rich On Tue, Dec 22, 2009 at 11:48 PM, cyrille henry <ch@chnry.net <mailto:ch@chnry.netwrote:
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 Cyrille Rich E a écrit : 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. Rich On Tue, Dec 22, 2009 at 11:21 PM, cyrille henry <ch@chnry.net mailto:ch@chnry.net <mailto:ch@chnry.net mailto:ch@chnry.net>> wrote: argggh. your are right : pd did not have permission to read the

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 Cyrille
