Lucid: wizardpen driver not loaded due to xorg module requirement mismatch?

Asked by Robert Saunders

I am using Kubuntu Lucid upgraded from Karmic (later I fresh installed Lucid but no difference to situation). I have been using the package at doctormo's repro as per the https://help.ubuntu.com/community/TabletSetupWizardpen page. Bugs and fixes as yet reported do not help in my case (cursor will not move from top left of screen). I am not writing this as a bug (Hope its the right thing to do - its my first time doing something like this) as in other ways my problem duplicates solved bug #552617. Making a 70-wizardpen.conf file as in the above bug report does not help, though (Instead of cursor at top left the pen has no effect whatsoever). The problem seems to be here in the xorg log:

I found a forum post that provides a solution for error due to module mismatch here: http://ubuntuforums.org/archive/index.php/t-1204537.html
However, adding the suggested section to 70-wizardpen.conf or xorg.conf causes a segmentation fault on reboot so X does not start. Here is the addition suggested on that forum page:

Section "ServerFlags"
             Option "IgnoreABI" "True"
EndSection

Here is some of the resulting xorg log showing the fault:

Segmentation fault at address 0x100

Caught signal 11 (Segmentation fault). Server aborting

So... Does anyone know another solution for this? If I have time I may try compiling the driver to see if that fixes it, but it would be nice if it worked for me through a package ;)
Thanks for the work you are doing getting these tablets to work well on Linux!
Regards
Robert

The fact that you are getting a seg-fault suggests that the module is not compiled correctly for your config.
Compilation from our source here should solve that (but I accept that it will take you some time to get all the dev-headers needed in place).

Which version of X are you using? As you can see from the log, the module is compiled for 1.6.0, presumably you are using something greater than that.

Thanks for the reply.

dpkg -l xserver-xorg-core shows X version 1.7.6.

I have tried to compile the driver from bzr branch following the wiki instructions at https://help.ubuntu.com/community/TabletSetupWizardpen. I have all the required packages listed there.
Generating the configure script works. I get stuck at:
./configure --with-xorg-module-dir=/usr/lib/xorg/modules

Hmm. You do have the pkg-config package installed, don't you?
The above output suggests you don't, or at least, it can not find it for some reason.

Thank you Ali Lown, for solving the problem!

For the help of anyone who experiences the same problem:
My fresh install of Lucid used X version 1.7.6 so did not work with the wizardpen driver from the doctormo ppa.
I could not compile after getting the bzr source as first I needed to install the package pkg-config (this was not in the list of needed packages in the wizardpen source README file or in the list on the community wiki) then ran ./autogen.sh and compiled as per wiki instructions.
After "make && sudo make install" I rebooted and my pen works well without the need for further other configuration (tested briefly in gimp and inkscape).
Thanks again!
