Demos work, utils dont

[emersonsc]

Raspberry Pi Zero 2 W
(2) 16x32 Adafruit Matrix Panels
Adafruit RGB Matrix Bonnet
Raspbian Bullseye 32bit Lite

Everything installed, no errors.

Example:
sudo ./text-scroller -f ../fonts/9x18.bdf -B0,0,255 -O0,0,100 -C255,0,0 --led-rows=16 --led-cols=32 --led-chain=2 "Contrast outline"
typical "CTRL-C for exit." output, but nothing on the Matrixs.

sudo ./demo -D4 --led-rows=16 --led-cols=32 --led-chain=2
produces entire matrixs to fade in and out with different colors (as it should).
