Setting up a 3M Serial Touchscreen
I’ve been attempting for quite a long time to get a Serial 3M Touchscreen to work on Ubuntu 10.04. The closest post I could find to what I needed was this one: http://ubuntuforums.org/showthread.php?t=1508944&highlight=3m+touchscreen Unfortunately, I get to where I touch the screen and the mouse jumps to the top right corner and that is it. The calibration software doesn’t really work (straight from 3M). Either sometimes it won’t start, or there is something wrong with it. It now looks like the problem has to do with the calibration software not recognizing the attached touchscreen. With some changes to the installation script, I was able to get the calibration software to install properly.

If I recall correctly, no one on the Ubuntu Forum was very helpful beyond pointing me to the same post. It seems «touchscreens» is a specialized topic that not a lot of people know much about. My questions: 1 Any tips to get this to work correctly? My major problem seems to be the newer boot process in 10.04. 2 Any alternative calibration software or touchscreen driver that may work or is worth trying? (serial, not USB). It seems that the the driver is not initiating correctly. The calibration software and control panel do not detect the controller for some reason. My assumption at the moment is that the init script is not correct, most likely due to changes in Ubuntu’s start-up process. Edit: It seems I can now run the control panel script correctly, I was having problems with Java, but I just had to execute it differently. Now I have the problem that the control panel and calibration software cannot detect the touchscreen. Everything runs, but just can’t find it, even though it’s connected and it responds if I enable the screen manually. The error is, «touchscreen 1 is not present».
