Known problems

There are some problems, that I haven't been able to solve: * Hotplugging - The driver doesn't support hotplugging - but this howto includes a partial workaround * HOTSPOTS - The driver doesn't support the HOTSPOTS of the tablet! - I'm working on a solution to this one!

Setting up your tablet

General information

This guide is based on the release: *ubuntu 6.10 (Edgy Eft) For the newest version, see TabletSetupWizardpen

Installing needed packages

Open a terminal Install some needed packages - Run this command:

sudo apt-get install xutils libx11-dev libxext-dev x-dev build-essential xautomation xinput

Downloading and installing the driver

Download the wizardpen driver, and extract it! - Run these commands:

wget http://www.dallerweb.dk/ubuntu/wizardpen-driver-0.5.0.tar.gz

tar -xvzf wizardpen-driver-0.5.0.tar.gz

cd wizardpen-driver-0.5.0

Fixing the issues with compilation of the driver in edgy

In edgy, there seems to be an issue with the compilation of the driver. To fix this, I've compiled the driver on dapper, and uploaded it to my site. To install "my" driver, run these commands:

wget http://www.dallerweb.dk/dl.php?file=wizardpen_drv.so -O wizardpen_drv.so

sudo cp wizardpen_drv.so /usr/lib/xorg/modules/input/

Setting up udev (If the tablet is USB)

Connect your tablet, if it is not connected yet. Find out what the device is called: (product) - Run this command:

cat /sys/bus/usb/devices/*/product

The output will look something like this: (depending on your system)

Tablet WP8060U
UHCI Host Controller
UHCI Host Controller
UHCI Host Controller
EHCI Host Controller

Note the product of the tablet (obviously Tablet WP8060U in my case!) Now, add a udev rule: (Note that the SYSFS{product} is tablet-specific! - See output from above command!) Run these commands:

sudo bash

echo 'BUS=="usb", KERNEL=="event*", SYSFS{product}=="Tablet WP8060U", NAME="input/%k", SYMLINK+="tablet-event", MODE="0666"' >> /etc/udev/rules.d/010_local.rules

exit

Restart udev - Run this command:

sudo /etc/init.d/udev restart

Check that the syslink has been created - Run this command:

ls -la /dev/tablet-event

If it outputs a line, it means that it succeeded!

Calibration

Note: In the subsection, you'll find output from calibrate! If you tablet is listed there, you can just use that output instead!

• If you tablet isn't listed, I would love to recieve an email with the output, and the model of your tablet! (See email at the end of the page!)

If you want to calibrate yourself, just proceed. Enter the "calibrate"-directory - Run this command:

cd calibrate

Build the calibration tool - Run this command:

make

Calibrate in order to find the edges of your tablet/digitizer - Run this command:

sudo ./wizardpen-calibrate /dev/tablet-event

Save the output from wizardpen-calibrate (the last 12 lines!) - You'll need it later in this howto!

Calibration output (If calibrate for some reason doesn't work!)

Skip this section if calibrate worked for you! Tablet W5540U (UC-Logic):

EndSection

Setting up X

Now we are ready to edit the xorg.conf file! Take a backup - Run this command:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Edit the file - Run this command:

sudo vi /etc/X11/xorg.conf

Press "I" - So that "-- INSERT --" appears! Insert the output from calibrate into xorg.conf: (just place it below your generic mouse!) Add the following line in the "ServerLayout" section:

InputDevice "WizardPen Tablet" "AlwaysCore"

Save the file, and exit the editor! (Press "ESC" and write ":wq" and press "Enter")

Making X start without a tablet connected

Now, the driver should NOT be initialized, if the tablet is NOT found! The wizardpen-driver does not support hotplugging, so we should run a script on startup, to define whether or not the tablet is present. Open /etc/rc.local - Run this command:

sudo vi /etc/rc.local

Press "I" - So that "-- INSERT --" appears! ...and insert some code: (insert it JUST above "exit 0")

XORG_CONF=/etc/X11/xorg.conf
if [ -e /dev/tablet-event ]; then
  sed -ie 's/^\(\s*\)\#\(\s*InputDevice\s\s*\"WizardPen\ Tablet\"\s\s*\"AlwaysCore\"\)\s*$/\1\2/' "$XORG_CONF"
  echo "Udev created /dev/tablet-event = Tablet present! - Tablet-driver enabled"
else
  sed -ie 's/\(^\s*InputDevice\s\s*\"WizardPen\ Tablet\"\s\s*\"AlwaysCore\"\)\s*$/\#&/' "$XORG_CONF"
  echo "Udev did NOT create /dev/tablet-event = tablet NOT present! - Tablet-driver disabled"
fi

...so that the file looks something like this: (in case you haven't added anything else to the file!)

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

XORG_CONF=/etc/X11/xorg.conf
if [ -e /dev/tablet-event ]; then
  sed -ie 's/^\(\s*\)\#\(\s*InputDevice\s\s*\"WizardPen\ Tablet\"\s\s*\"AlwaysCore\"\)\s*$/\1\2/' "$XORG_CONF"
  echo "Udev created /dev/tablet-event = Tablet present! - Tablet-driver enabled"
else
  sed -ie 's/\(^\s*InputDevice\s\s*\"WizardPen\ Tablet\"\s\s*\"AlwaysCore\"\)\s*$/\#&/' "$XORG_CONF"
  echo "Udev did NOT create /dev/tablet-event = tablet NOT present! - Tablet-driver disabled"
fi

exit 0

Save the file, and exit the editor! (Press "ESC" and write ":wq" and press "Enter") Now you can test udev's ability to detect the tablet - Run this command:

sudo /etc/init.d/rc.local start

The output will tell you if it is present or not! - And it should match reality! (try to disconnect it, and try again! - connect, and then again! - etc...) You should now be able to restart X and have the tablet working as a mouse. I'm still working on a way to support hotplugging, but the above code-example will make X start without a present tablet.

Fix the X-freeze problem

This is not possible, if you are running edgy, and not able to compile the driver correctly! This is a workaround to avoid an X-freeze if you unplug your tablet while X is running. Open the file wizardpen.c, go to line 632, and remove these 4 lines:

if ((local) && (local->fd))
xf86CloseSerial(local->fd);
if (local)
xf86DeleteInput(local, 0);

These 4 lines deactivate the driver after an unplug, which is a good thing in itself. The sad thing is that xorg doesn't understand such a deactivation. After removing the lines, you should compile the driver again - Run this command:

xmkmf && make

Copy the newly-compiled driver to the driver directory - Run this command:

sudo cp wizardpen_drv.so /usr/lib/xorg/modules/input/

Configuring the buttons on the pen

I'm working on a wizard for this task! In the meantime, look into the package "xinput" which is installed first in this guide. Here is a list of numbers with their corresponding function:

Number	Function
0	No action (only movement)
1	Left button click
2	Middle Button click
3	Right Button click
4	Scroll up (one click equals one step of scroll wheel in my logitech mouse)
5	Scroll down

Configuring the tablet HOTSPOTS

I'm working on a daemon for this task! It's working almost well so far, just need a little tweaking, and making it start automatically. The biggest problem is to execute the commands as child-processes (so that a failure doesn't cause the daemon to die!)

Troubleshooting - See this if you have any problems

I have followed the guide without getting errors, but it still doesn't work!

On edgy you will get no errors if you compile the driver yourself. But for some reason, the compilation is flawed! (because of the new GCC version) You can see these errors by running this command:

cat /var/log/Xorg.0.log | grep "wizardpen"

See this for a fix: (or the troubleshooting below...) https://help.ubuntu.com/community/TabletSetupWizardpen#head-2b7a38de2ee5f77258591f0f1e7984a761bed268

The command cat /var/log/Xorg.0.log | grep "wizardpen" outputs errors

The output of cat /var/log/Xorg.0.log | grep "wizardpen" may reveal several errors, some of them are: Module present, but with compilation-errors: (please see: https://help.ubuntu.com/community/TabletSetupWizardpen#head-2b7a38de2ee5f77258591f0f1e7984a761bed268)

 (WW) Warning, couldn't open module wizardpen

The Xserver is not starting after playing with the xorg.conf file

Wow - That's bad! - First of all, check that you set everything right! Well, I suggest that you drop me an email, telling me what went wrong! And then just restore the backup we created - run this command:

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf

Everything seems to work, except pressure sensitivity

All the tablets mentioned in "known tablets" has pressure sensitivity support in Linux! Please make sure that your favourite application supports pressure sensitivity.

Application	Support for pressure sensitivity	Guide
Krita	Full support since 1.6	Non yet
Inkscape	Full support	TabletSetupInkscape
Gimp	Full support	TabletSetupGIMP

Please tell me about other applications!

Pressure sensitivity works, but is not calibrated well

The section we inserted into xorg.conf holds some options to calibrate the area of the tablet, but I haven't put in options to configure pressure sensitivity, since it varies a lot. You can insert these options to enable MAX and MIN pressure sensitivity: Option "TopZ" "10" Option "BottomZ" "511" Option "MaxZ" "511" Where "TopZ" represents the lowest pressure-level to accept, and "BottomZ"/"MaxZ" represents the maximum pressure-level to accept.

I have problems not solved by the above troubleshooting

Maybe I can help! I assume your terminal is in the calibrate directory! (daniel@daniel-laptop:~/wizardpen-driver-0.5.0/calibrate$) Plug in your tablet FIRST (If not already plugged in), and THEN run these commands:

cd ..

cd debug

./debug

The last command (may take some time to execute) will create the file "errorlog" which holds the information I would like in order to be able to help you! Please mail me on: [email protected] (And don't forget to attach the errorlog!)
