Received my new hyperpixel 4.0 Touch, connected it to my PiZero W and expected that after installation (with the one-line installer script) that I’d be able to touch the screen and it would react - this is what the instructions suggest.
I get a desktop display but no touch behaviour as far as I can see.
I saw an older thread about hyperpixel3.5 touch issues and how to investigate, but the various logs and services mentioned there don’t seem to apply to the 4.0?
Anyone got any suggestions on how to diagnose it or am I likely to have a faulty unit?
I am using an existing Raspbian Stretch installation and it is allegedly up to date. .
