From the default NOOBS installation I have installed Raspbian. It seems NOOBS has added some settings to the config.txt file, where one of them is:
hdmi_force_hotplug=1 which forces video to be on the HDMI port. Now imagine you have only an RCA cable (+an old tv), and a Windows computer, how do you remove that one line from the config.txt?
I've been wondering if there would be some key that you could hold down during the boot to override these settings, but I can't find anything like that?
Otherwise I have put the SD card in my Windows machine, and there I can find
os/raspbian/boot.tar.xz which I can open with 7-Zip, and which contains a config.txt file. But that file does not seem to have the NOOBS added lines.
What is the easiest way around this? (I will need to explain it remotely to a beginner, once I find a way.)
