OS: Ubuntu 11.04
Arch: AMD64
Desktop Manager: Gnome 3

I recently blew away my Ubuntu 10.10 and installed 11.04. Not liking Unity, I figured I would try Gnome 3. After getting Gnome 3 set up, I downloaded babl,gegl, and gimp tarballs and proceeded to install all sorts of dependencies (required and many optional ones) via apt-get packages.

I then compiled babl(0.1.4), gegl(0.1.6), glib(2.29.8) gtk+(2.24.5) and finally gimp 2.7.3(note that all the above are from the gimp.org ftp site. Prior to compiling gtk+, gimp failed on the make with some really strange errors(sorry... I don't have them any more) which is why I compiled my own copy. Also note, ALL of the above were compile into a different prefix with :

./configure --prefix=/home/joefrazierjr/opt

Once I finally got GIMP compiled, I can see my tablet in the input devices, but they are greyed out along with all of the below:
SynPS/2 Synaptics TouchPad
Virtual core XTEST Pointer
Wacom Bamboo Fun 6x8 cursor
Wacom Bamboo Fun 6x8 eraser
Wacom Bamboo Fun 6x8 pad
Wacom Bamboo Fun 6x8 stylus

The ONLY thing that is NOT greyed out is Core Pointer.

The main reason I complied is because for whatever reason, the PPA package available does not also install Python(but does let the tablet work), so I am kind of stuck here.

Note that I am comfortable with "using" the shell, but am a power user in linux, so please assume that I know nothing about linux in any replies. Also, if I need to remove, any of the compiled code and recompile, I assume running "make clean" will fix it up correctly?

Note, my Bamboo Fun works fine in MyPaint(with pressure sensitivity, etc), so the issue is with either GIMP compile itself or GTK apps in general(I have no idea if MyPaint is GTK or not so someone might be able to rule that out).

Also, I still have the build folders, so if I need to link to any of the config.log files, please let me know and I will put on my dropbox.

Thanks or any help! Joe

I suspect this is a wacom driver problem of some sort, but the folks that can really help are on a different mailing list wacom-discuss. If you follow the link below you can sign up to it.

https://lists.sourceforge.net/lists/listinfo/linuxwacom-discuss

They are HUGELY friendly and responsive. They'll ask for some information,

maybe then for some more information and pretty quickly they will diagnose the problem. You'll be happy!

No, I would say it has to do with the GIMP build process itself. Long story, short after 4 re-installs I have come to determine that the 2.6.38.* kernals don't seem to like (some????) nvidia cards. I googled and tried tons of things with no luck. Sooooo...I ended up reverting back to 10.10 and am hoping 11.10 will actually work correctly with my video card(on a laptop.. so can't switch out!).

On 10.10, I installed gimp 2.6.* from apt package and the pen works with pressure sensitivity AND the input devices work correctly for editing. ie, Gimp 2.6.x works fine.

I then built/compiled all of the prerequisites(Glib, GTK+, gdk-pixbuf, pixman, cairo, babl, gegl) and then gimp into its own prefix BUT the same issue is happening, so all I can assume from this is that it has to do with some from the build process(or something missing!) However, this time while the items are all greyed out, the pen pressure DOES work this time. The thing that does not work is the stylus/eraser(meaning that they won't 'bind' to separate tools and remember them). Ie, it's working as a regular mouse + pressure. One thing I did see when configure ran was in the optional modules section of the output, I got this:

Linux Input: yes (GUDev support: no)

While this is a bummer, it is something I can live with for a few months until 2.8 is actual release and hopefully the packaged build will work properly even if I have to build the prerequisites manually. Hopefully by that time, 11.10 will also be released and I can make a test partition to see if it agrees with my video card.
