I have RPI4 model B and I've installed Kali Linux Kali Linux RaspberryPi 2, 3 and 4 on my SDcard 64gb through Balena Etcher but when powered on, my LG tv shows "no signal", HDMI is well connected.

I tried in config.txt:

  • hdmi_force_hotplug=1 -> "no signal screen"
  • hdmi_safe=1 -> "rainbow color splash screen"

Could you please help me ?

  • check HDMI cable
  • set hdmi_safe=1
  • try set parameters hdmi_group and hdmi_mode for your display (watch next point)
  • read this link
  • Thank for help, it did not work, I tried that already. :( But I formated the SDcard again, and connected it to my laptop with USB-SDcard adaptor this time (was SDcard adaptor before). Tried only hdmi_safe=1 option, and 1sec after rainbow it has booted. But at the end I have black screen blinking with the mouse. There is nothing I can do. This is a nightmare :)

  • hdmi_safe includes hdmi_force_hotplug (ie., enabling them both is harmless but redundant): raspberrypi.org/documentation/configuration/config-txt/video.md

  • @WBRPI4 then the problem is most likely in drivers or the graphics environment cannot boot for any other reasons Jun 30 '20 at 10:28
  • @goldilocks indeed, did not notice when reading the documentation Jun 30 '20 at 10:29
