Suddenly I cannot enable my Hyperpixel (not 4) display. Have not used it for a while. Installed it on a RPI 3B, with Bullseye 32 bit and rand the install script. All went well, but the display does not come on. The HDMI does work though. Same if I take the HDMI cable out.
Linux raspberrypi 5.15.56-v7+ #1575 SMP Fri Jul 22 20:28:11 BST 2022 armv7l GNU/Linux
The hyperpixel services statuses are (see below) and there is a touch error, and further down my config.txt:
