I finally got around to attempting to hook up the 15" touchscreen I purchased off eBay to the mill's PC. I was initially quite impressed as Ubuntu 6.06 recognized it as a Micro Touch screen and loaded the appropriate USB driver right off the bat. What I didn't realize is what a pain it was going to be to get X to recognize it as pointing device.
To make a long story short, I searched the net for any and all documentation regarding this and found very little. Google just wasn't giving me the results I wanted. I finally pieced together enough information to get it working, but I wish Google had sent me to this web site first. That is exactly the procedure I ended up using. Had I found that site earlier it would have saved me many hours and curse words!
