tried to save file but the file cannot be re written to.

any advice on how to get access to edit and save to the txt file would be really helpfull.

thanks in advance

have searched forum but cannot find relevant info. not too technical but can follow instructions OK.

load up terminal, switch to the folder the file is in, then type "sudo nano filename"

What editor are you using? Are you editing on the Pi itself? If using an editor from the command line did you precede the command with sudo? Eg.:

Code: Select all

sudo nano /boot/config.txt

(I suspect you have a "file permissions problem")

Two ways:

On a PC (or Apple or Android device) open using word, or native text editor:

Insert micro sdccard in to reader, then open 'config.txt' file, make changes, save file. Then insert sdcard into pi.



In a terminal screen on pi itself:

Code: Select all

sudo nano /boot/config.txt

To SAVE changes:
Hold 'Ctrl' and 'x' at same time, then 'y', then 'enter'

Then, in terminal:

Code: Select all

sudo reboot
