Question
Elo touchscreen Pointer Movements Reversed
I have a Elo 1939L 19" Rear-Mount Touchmonitor which is behaving oddly: touch the screen and the pointer moves left for right, right for left, up for down and down for up and stays about 1/3 of the screen away from where you actually touch. All cases using the USB cable (a serial is provided but I've not tested it.)
I've tried installing the drivers provided by Elo touchscreens. Also, under Ubuntu, the touchscreen is automatically recognized. I've tried 2 completely different sets of hardware (computer) and 2 different distributions of Ubuntu, each with clean installs as well as boot from CD environments. I've not tired any other flavor of Linux (prefer to stick to Ubuntu for this project). Each case, the behavior is the same (reversed on both axes).
I'm handy enough with vi, but recompiling kernels is above my skill level. I've googled the problem and found some hopeful fixes like changing the x and y axis values, some tweaks to xorg.conf, and some clever inverse technique, none of which worked.
Any thoughts?

I am still watching, the other programmer at our shop has it to a point where it works and then doesn't. He says 90 percent of the time he can get it to work. He too believes it to be the HIDCompliant drivers getting in the way. He wants to recompile but his plate is as full as mine.
I am still watching this one also...

while there hasn't been any comments added, this is still an issue and i come in here to see. Myself and another programmer have been working on this and are making headway. It appears that Ubunto is the way we are leaning and we are 99% working on the ELO monitor with it and some third party drivers.

it was only 8 days since we last posted in here...not 14...We are working toward this. It is slow. We recompiled the kernel on centOS but now we need to recompile all the other packages connected to it. The other programmer I work with was working on it and he ended up in the hospital..
will fill in when I have more

I have actually been trying different touch screens and have a prototype from another company. The only one, but with not any success there. They are targeting windows platform also. ELO just came out with a newer model that is a tad cheaper but still works the same. Supposedly some new drivers are coming out on 11-09, from what my friend and coworker has said. He succeeded in getting the monitor to work with a tablet driver in ubunto 8.12 I think was the version. Problem was it snapped to 1/2in. grid squares which was not acceptable. wf, I am on yahoo with same.

I am currently working on the same issue. I have too many things going on so haven't tried recompiling the kernel yet, but it appears as thought the HiDCompliant drivers don't like the elo monitor. I will be watching this one to hear what others have to say. I haven't done it in Ubunto though, it was CentOS 5 and the HID is hard compiled into the kernel. I managed to correct the x and y but the scale of movement of the mouse is not correct. The further I move my finger on the screen, the mouse pointer moves further and at a greater distance as I move, increasingly.
