Ok, we have a brand new RPi, an SD-card with the latest Raspbian, some brand new monitor with HDMI-input only.
Everything is set up, the power plugged in, one LED shines, another one, then “no signal” on the monitor.
0. SSH-access not possible due to the fact that because of those botnet-takeovers of RPi in the past the default access was disabled for fresh images.
1. Wifi with VNC also impossible, because how to set the Wifi-credentials if you can’t see something?
2. VGA not possible due to hardware-limitations.
Great 🙂 I love when soft-/hardware does not work out of the box :’)
After a while of tinkering I remembered that I had to enforce the HDMI-ouput on the first RPi (the one for the catcam).
Can be set inside /boot/config.txt (leafpad is the current default editor on Raspbian).
# For more options and information see
# Some settings may impact device functionality. See link above for details
# uncomment if you get no picture on HDMI for a default "safe" mode
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
# uncomment to force a console size. By default it will be display's size minus
# uncomment if hdmi display is not detected and composite is being output
# uncomment to force a specific HDMI mode (this will force VGA)
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
# uncomment for composite PAL
#uncomment to overclock the arm. 700 MHz is the default.
# Uncomment some or all of these to enable the optional hardware interfaces
# Uncomment this to enable the lirc-rpi module
# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
# additional shit by me
