I am trying to edit the config.txt file so that I can add the licence codec key codes. I have noobs and Raspbian installed on the Pi.
When I use the text editor that comes with Raspbian to try and edit the config.txt file in the boot directory so that I can enter the commands and codes, it will not let me save the changes. I realise that you need to enter sudo commands as a super user to do this, but can not figure out how to do this. I am very new at programming and Linux so I need instructions for someone with little knowledge of the subject. I am pretty sure that the micro SD card is not write protected, as I was able to configure it and load noobs and Raspbian on to it. What am I missing??
