On our school we're using latest DAPPER. But the problem is with GOK since it won't start and now several of our students with special needs cant work on the computer.

Code:
dijaki@zavod:~$ gok
/dev/js0: No such file or directory
The program 'gok' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDevice, invalid or uninitialized input device'.
  (Details: serial 161 error_code 168 request_code 145 minor_code 3)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

and my 'xorg.conf'
Code:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I think you should file a bug in the Ubuntu bug tracking system.

well I already did that but there appears to be no response:
https://launchpad.net/bugs/42308

And this situation is critical for our school. Since if this bug isnt fixed we'll have to be moving back to WinXP. And the school administration will blame us admins for trying out linux...

I've tried the version present in Debian (1.0.10) but is way broken, it doesn't even start ( http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=369864 http://bugzilla.gnome.org/show_bug.cgi?id=343536 ). Anyway there's hope, as the upstream developer seems quite responsive about the bugreport.

In the meantime, if you are comfortable with it, you can try to build and install it from source, maybe it works.

FYI, the latest Debian Gok package (1.0.10-2) is working...

Here comes the solution:
sudo vi /etc/X11/xorg.conf

Comment out these lines:
Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "stylus"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "eraser"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/wacom" # Change to
# /dev/input/event
# for USB
Option "Type" "cursor"
Option "ForceDevice" "ISDV4" # Tablet PC ONLY
EndSection

*** and also ***
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
under Section "ServerLayout"

Now, save the file and reboot.
Enjoy yourself with gok!

Sorry but above solution is far from a solution. When using a (wacom) tabletPc, than you need the GOK. So disabling the tabletpc is not nice solution.

The other solution I tried for a whole evening searching and trying was using
"the latest Debian Gok package (1.0.10-2) is working" hint.

Well I'm not a hacker Confused so downloading the debian package and installing in Ubuntu 6.06 gave an dependency problem....

Forced installing still didn't work. Is there anyone who has the right package for UBUNTU 6.06

Other question who should be mentioned in the ubuntu team to do an update on gok in the ubuntu repositories? Well I'll go on with my search too.

Thanks to all the programmers who already made possible ubuntu.

In the package description there should be a field called "Maintainer:" with an email address.

My suggestion is to compile the Debian GOK package from source...

I hope you can follow this up with Ubuntu -- perhaps in their bug tracker. Please note there are Ubuntu bugs filed:
https://launchpad.net/distros/ubuntu/+source/wacom-tools/+bug/40473
https://launchpad.net/distros/ubuntu/+source/wacom-tools/+bug/40806
As well as a resolved "GOK bug":
http://bugzilla.gnome.org/show_bug.cgi?id=350356

Notice the initial Ubuntu report has an alternate solution to the one provided in this forum. HTH
