DigiPro drawing tablet on Fedora 12

I just bought a DigiPro 5″/4″ drawing tablet to run with my Fedora 12. When plugging it in, the system recognized it, but every time I touched the tablet with the stylus pen, the cursor went to the upper left corner. Clicks worked OK, but it looked like the system needed to know the tablet’s dimensions.

To the system, this tablet is UC-LOGIC Tablet WP5540U. How do I know? Because when I plug it in, /var/log/messages gives:

To get it going, I followed the solution in Fedoraunity (which requires registration to access, would you believe that!)

First, I downloaded the wizardpen RPM package from here.

And installed it:

# rpm -i wizardpen-0.7.0-0.fc12.x86_64.rpm

And then ran the calibration utility. To some this goes with /dev/input/event8, just play with the numbers until hitting gold:

# wizardpen-calibrate /dev/input/event6

Please, press the stilus at ANY
 corner of your desired working area: ok, got 1928,3766

Please, press the stilus at OPPOSITE
 corner of your desired working area: ok, got 30360,28914

According to your input you may put following
 lines into your XF86Config file:

Driver        "wizardpen"
 Option        "Device"    "/dev/input/event6"
 Option        "TopX"        "1928"
 Option        "TopY"        "3766"
 Option        "BottomX"    "30360"
 Option        "BottomY"    "28914"
 Option        "MaxX"        "30360"
 Option        "MaxY"        "28914"

Now, one of the side effects of installing the wizardpen RPM package was that it created a file: /etc/hal/fdi/policy/99-x11-wizardpen.fdi which is a HAL fdi file. If you’ve edited an xorg.conf file, that should be old history. Instead of the mumbo-jumbo above, there is a new mumbo-jumbo, which is supposed to work even if the device is hotplugged. No need to restart X for new devices! Hurray!

So I downloaded the recommended XML file from here,  modified the variables according to my own calibration, and saved the following as /etc/hal/fdi/policy/99-wizardpen.fdi (and trashed the previous file. The names are slightly different, who cares).

<?xml version="1.0" encoding="ISO-8859-1"?>

</match>
</device>
</deviceinfo>

According to the reference mentioned above, there’s a need to relogin. It turns out that replugging the tablet to the USB jack is enough to get it up and running OK.

To make GIMP respond to pressure sensitivity, set up the input device as follows: Edit > Preferences > Input Devices, press Configure Extended Input Devices. Under Devices find the tablet’s name, and choose the mode to Screen.
