A client of mine has several old PCs with a 19" touchscreen (kiosk systems). So far there was WindowsXP installed.
Now I made a clean Ubuntu 14.04 installation (Unity only, no other desktop). I need to mention, that this is the first time I'm working with Ubuntu. Please be patient with me - I'm a real novice. ;-)
Everything looks fine, except the Touchscreen does not work. The screen is connected to the serial port (ttys0). Hardware is working - a cat ttys0 shows that signals are coming from the screen.
Somehow the driver does not recognize the device. Tried all kind of settings that I found in different forums. I guess most were for older versions of Ubuntu. Anyway, nothing worked.
I don't have a specific driver for the touchscreen. Somehow I need to get it working with whatever driver that comes with Ubuntu. No fancy stuff - like multitouch - required.
I'm sure, there is a simple way to tell the standard input driver how to recognize the serial port.
Any help is highly appreciated! Thanks!
