Touchscreen not working after new install on Rpi
I have a Rpi 4 with a Waveshare capacitive touchscreen which used to work fine right out of the box.
Recently I ran into problems with my repetier server. Google Chrome always popped up with a privacy screen which I couldn't get rid of (I updated the image once per apt upgrade and what I have been reading in the forums that might be the cause for this.
So I decided to download a new image file and restored the setup from backup. (btw not a straigt forward operation)
First, I was surprised, that the camera settings weren't restored so I set them up manually.
The contents of the screen is now ok, but the touchscreen is unresponsive.
I have changed absolutely nothing not even a single usb connector but it still doesn't react.
The Rpi all in all seems to be much slower now.
Can anyone explain or speculate what is going on?
