[DIGImend-devel] Genius PenSketch 12x9 in Ubuntu Precise (12.04)

[Favux ... <fav...@gm...>]

Hi Nick,

I have a Genius PenSketch 12x9 user on Ubuntu forums.  Originally he
was using Natty (11.04) and wanted to modify his tablet's aspect
ratio.  We figured that out.  Then he upgraded to Precise (12.04)
because he wanted to install the new Gimp 2.8 over the default Gimp
2.6.  After he did that all was well.  Then he added the custom .conf
file to modify the aspect ratio and the tablet stopped drawing.
Removal of the custom .conf didn't fix things.  Also since installing
Gimp 2.8 was  about the first thing he did a bunch of updates for
Precise were installed, maybe at about the same time as the .conf
file.  He can't remember quite when or what they were.

Bus 003 Device 003: ID 5543:0042 UC-Logic Technology Corp. Tablet PF1209

xinput list:
⎜   ↳                 9x12 Tablet                 id=10    [slave  pointer  (2)]
⎜   ↳                 9x12 Tablet                 id=11    [slave  pointer  (2)]
⎜   ↳                 9x12 Tablet                 id=12    [slave  pointer  (2)]

In Xorg.0.log we see the the 3 event nodes.  The first and third have
the identifier "evdev tablet catchall" while the second has "evdev
pointer catchall".

Are there suppose to be two event nodes matching MatchIsTablet?

It appears the pen may be on the third event which may be why the pen
isn't working in Gimp 2.8.  It still has the issue/bug Viktoria.S
described where it is showing one input device, namely "9x12 Tablet"
in its Configure Extended Input Devices dropdown.  Because by happy
chance the pen was the first device Vicktoria.S reported things were
OK for drawing even so.  I can't explain how the pen event changed
from the first to third for the PenSketch if that is what happened.
Maybe the updates?

So <device names> that are different would be good.  I was wondering
if maybe that could be done through  udev rules.  That would be one
step up from the linux wacom X driver appending the different input
tool types but still not require kernel driver changes.  So far in
udevadm info I do not see a difference.  In other words I cannot find
whatever MatchIsTablet, MatchIsPointer, or MatchIsKeyboard is matching
to in udev.

In the PF1209's case is it the HID report descriptor's "Usage
(Stylus)" that triggers MatchIsTablet?  And "Usage (Mouse)" for
MatchIsPointer?  Do you know if that shows up in udev and if it does
how does it show up?
