as far as I am concerned, this bug may be closed.

Some good news from my side here: we have successfully deployed six
PM9000 (RS232) based touchscreens in a production environment, with the
latest (beta) Ubuntu 8.04 driver and calibration tool provided by
Penmount themselves.
Working just fine, both the driver as the calibration tool inside a

hmm, I don't see any difference between the files you have in your PPA
for gutsy and for hardy. diff also doesn't see any difference. :-) I'll
test them nevertheless...
the support from PenMount indeed is worthless. just look at their
website. if there would have been an Internet in the sixties, t
We are testing on a PM9000, connected to TTYS3 on our system.
I agree the problem lies upstream here. I tried to get them involved as
well through the official support line of the company where we bought
our screens (they claim they support Linux after all), but no luck until
now.

removing mouse_drv.so has no effect whatsoever here. anyway, the problem
is not with stability or anything else, only with the fact that the
mousepointer just doesn't stick to the position where your finger is.
it's not only a point of calibration, because the relative position

ok, sorry, my bad again (it's getting late :-)). I messed up hexadecimal
and binary notation here.
anyway, I'm stuck. from the code above, you can tell that packet[1] is
responsible for the greatest part of the X coordinate value. when I put
my pen in the top left corner, this packet contains a de
hmm, the displacement cannot be solved by a simple linear
transformation. it's very weird actually. I added some debugging lines
to the driver to print out the X and Y values it reads from the serial
port (testing on a PM9000 here) and when I'm following the far left
border of the screen with the p
hehe, I was stupid trying to fix the swapped Y-coordinate with that line
of code. digging deeper into the existing code, I found out I could play
around with the settings changing the PMode. for my screen, simply
setting it to 2 made the X-Y interpretation correct.
I'm still puzzled by the calibra
same problem here with the Y-axis swap. adding the following code on
line 1165 (right after where the x and y values are read form the serial
pins) fixed that for me:
y = priv->screen_height - y;
problem still is that priv_screen_height doesn't seem to be set to the
right number. the transformati
