Hi all. I have an existing touch screen that I’ve been using with a Jetson TX2 and it supports touch events, but not any multi-touch events.

Based on some other forum entries I’ve read, it seems that it should be possible but I might need to write my own driver for that.

Can someone provide some info on this? Hopefully it is possible without needing a custom driver.

I have a chalk-elec 7-inch display that has micro hdmi and usb ports.

Hi james\_arcgis,

Not sure how your touch screen worked with your TX2, you will need to find out how it work, then see if possible to leverage it to Nano.

Thanks kayccc,

```
One of the touch screen inputs is usb, so presumably it's using that interface for the events. With the Ubuntu support, it recognizes the input as touch events so I can configure it to popup the on screen keyboard. What I cannot do is get it to recognize multi-touch events like pinch and zoom on iOS or Android.
