Touch not working at all withQT

[Peter G.]

Hello,

I am currently trying to get a QT application with touch to work, but the touch just isn't working. I am not sure what the problem is, although I suspect that the drivers are missing.

I am running the A20-OLinuXino-LIME2-eMMC with the LCD-Olinuxino-7TS screen.

I searched, but couldn't find any download for the touch drivers.

Where can I download the touchscreen drivers?
What's the best way to troubleshoot the touchscreen?

Trying to list touchscreens, like described in this post, isn't working. (http://www.ptrackapp.com/apclassys-notes/embedded-linux-multitouch/)

# ls -rlt /dev/input/touchscreen

> /dev/input/touchscreen does not exist

furthermore, the folder "/sys/devices/virtual/input" does not exist.

is this a driver issue?
