did it not come with some calibration software? IIRC one would then hit a
dot in the middle and one in each corner and it would give the numbers one
needed.

Hi everyone -
I'm running LTSP-5 and so far I cannot calibrate an ELO Touchscreen
properly.
It is an ELO 1715L attached to a terminal.
In lts.conf I have set:
USE_TOUCH = Y
X_TOUCH_DEVICE = /dev/ttyS0
This allows me to use the touchscreen but my finger and the cursor are not
in the same place on the screen.
At bottom left corner, the cursor is a bit to the right and above my
finger - maybe 1cm in both directions.
As I move towards upper right corner, cursor gets further and further away
from my finger. The cursor becomes maybe 6cm above and to the right of my
finger at the extreme position. The cursor reaches the corner much before my
finger does.
I have tried setting values for X_TOUCH_MINX (and MINY) and X_TOUCH_MAXX
(and MAXY) but it makes no difference.
I also tried setting MinX MinY as suggested in
http://osdir.com/ml/linux.terminal-server.devel/2004-10/msg00003.html
but it makes no difference.
Does anyone have any ideas or know how to fix my problem?
- David
