HOW TO Set Up the Bamboo Pen & Touch in Lucid

[earendil02]

Thank you very very very very very much!!! I try immediately and'll let you know the results...

[earendil02]

I completed the part I

Install input-wacom-0.13.0's wacom.ko

replacing "input-wacom-0.13.0.tar.bz2" with "input-wacom-0.16.0.tar.bz2" in the wget and tar commands, and consequently entered "cd input-wacom-0.16.0" instead of "cd input-wacom-0.13.0". I got absolutely no errors in this part.

After reboot though the tablet didn't work as before, getting

$ lsmod | grep wacom
wacom                  29661  0

when checking the module.

So I jumped to step b) of part

II. Install Xorg's xf86-input-wacom tar or clone the git repository for Lucid, Maverick, Natty, & Oneiric

.
All goes ok until "make", then I get (I worked in an empty directory named Bamboo instead in Desktop as indicated in the post since the beginning of the re-installation procedure):

~/Bamboo/util-macros-1.8.0$ make
make: Nessuna operazione da eseguire per "all".

(translation: no operation to execute for "all")
I stopped here for this step, and tried step a), but this time checking out better the output of command "make" I noticed a lot of warnings and "errors" like that just mentioned. Here's the whole output:

~/Bamboo/xf86-input-wacom-0.15.0$ make

I don't know what to do now, and of course my table still does not interact with my laptop.
Hope you understand what's wrong!!

Well the warnings can be because of stuff they've introduced and maybe not yet making appropriate adjustments in the Make file. Usually they can be ignored. As long as there are no errors or fatal errors the wacom.ko should compile and be in the 2.6.30 folder. The main thing is when you run the copy (cp) command to put the new wacom.ko in place is whether it works or not. If it just returns to the prompt it did otherwise it will give a stat error.

What I'm confused about is the output says input-wacom-0.15.0 and I thought you were now using 0.16.0.

Given the version of xf86-input-wacom you have as soon as you have a working wacom.ko in place and reboot the tablet should work. I don't think that is true of the default xf86-input-wacom (wacom_drv.so) that came with Lucid but Chris changed the later ones so any model BambooPT would be recognized without having to add them explicitly to xf86-input-wacom.

What I'm confused about is the output says input-wacom-0.15.0 and I thought you were now using 0.16.0

I didn't notice this, I fixed the numbers and redid all the passages in part II (rebooting twice) but nothing changed (in terms of input-response).
Now I don't know what else to try...

[earendil02]

Strange fact: I checked again the version and it's changed downward!

$ xsetwacom -V
0.16.0

Before it was 0.18.99 (??)
May it be somehow significant??

Well my guess is something is going wrong with input-wacom but right now I can't tell what. I'm not seeing a show stopper Error in the output you are showing me. You have me wondering now if there is a problem with third generation support for the 2.6.32 kernel.

I think I'll need to look at this with my 470. One thing to mention is when you recompile using the same input-wacom folder you can start fresh by running make clean when you change directory into the input-wacom folder. Sometimes a previous compile can interfere and so you want to clean it out.


Edit: Well it looks like maybe you compiled xf86-input-wacom-0.16.0 thinking it was input-wacom-0.16.0. And that's why it changed downward.

Thank you again for your help and dedication... I will try later to redo everything using "make clean", but I haven't many expectations... I hope this problem will be solved soon, meanwhile I'll use the tablet under windows (sigh) and maybe I'll study more for university
Anyway I'll keep you up to date...
Thank you again!!

I tried redoing all the passages using "make clean" instead of "make" and using every time the most recent packages available at linuxwacom, but nothing changed. So I tried to follow the alternate instructions decribed in this post: http://ubuntuforums.org/showpost.php...12&postcount=1, but even this didn't worked.
I rebooted at least 7-8 times, but my tablet does not work.
A doubt arises: in the instructions linked above it's said:

To verify the linuxwacom kernel module is present in the correct location:

modinfo -n wacom

I tried obtaining:

$ modinfo -n wacom
/lib/modules/2.6.32-45-generic/updates/dkms/wacom.ko

I thought the correct path should have been "/lib/modules/2.6.32-45-generic/kernel/drivers/input/tablet/", since I copied the driver there, so maybe this is a possible error. But since I don't know much about how drivers really work and where they're stored, I simply report this fact to you, hoping you'll explain me.
Thank you again!

Ah, oops. I should have asked you this before.

Did you by any chance install a Wacom driver PPA at some earlier point? If so do you remember which one?

[earendil02]

I'm not shure 100%, but I think I did... checking with Software Center (searching "wacom") I found I have "wacom-dkms" and "xserver-xorg-input-wacom" installed, and I think the first one is PPA...
