Hi all, this is my first post. I would use Zero 3W in an headless mode, just with a USB peripheral connected and WiFi. How can I really disable the GPU and other stuff that can reduce the power consumption and lower the temperature?
At the moment I’ve installed radxa-zero3_debian_bullseye_xfce_b6.img.xz
I’ve also tested the cli version but not boot the board.
I’ve disabled the lightdm service so the desktop manager doesn’t start and I manage the board via SSH. But temperatures are really high! I’ve changed the governor to powersave, and the board is running at 408MHz.
sensors reports:
