I have a Gvision L15AX with a
serial touchscreen.
Setting up the elo drivers was more difficult for me than it needed to be. I tried to use the drivers provided by Elo with no success. At first I was confused as to the drivers I needed but found a hardware chipset/ driver list for touch screens here:
http://touch-base.com/documentation/...ontrollers.htm
So I needed the elo drivers and I downloaded them from here:
http://www.elotouch.com/Support/Downloads/dnld.asp
They didn't work for me. I followed the walk through and had no luck. I wasn't even successful at removing them.
So with a fresh install of Debian Etch (the Xserver graphics were messed up in Lenny) I installed the elographics package.
Code:
aptitude install xserver-xorg-input-elographics
I knew by touching the touch screen with
that my touch screen was on /dev/ttyS1.
Then I edited /etc/X11/xorg.conf
The options are available through:
My Y axis was flipped so I had to invert the max and min values. I would just change the values a little and then type ctrl+alt+backspace to restart X to test the new settings.
Important to know is that the minimum X,Y coordinates are for the top left and the maximum x,y coordinates for the bottom right. (So you:
touch the top-left to see how close your minimum values are and
touch the bottom-right to see how close your maximum values are.)
There's a picture here:

(and some xorg.conf examples)

I am very happy with the people that provided the Debian elographics package and wish I had know to try that first.
You can check to see what's going on with 'od' but I didn't know how to decipher the output.
Code:
od -w8 -d </dev/ttyS1
There's also touchcal available on Sourceforge but it didn't compile for me.
