I can change values in the config.txt file but the system will not allow me to save the changes.It reports "unable to open file" What am i not doing?

You need to be logged on as the root user in order to make changes to config.txt.

I am logged in as Root The system returns a message" /usr/bin/x-terminal emulator prog'
was started with the privilages of root without the need of a password due to systems
authentication mechanism setup"

Not sure how your setup is or the command you used to edit

But typically just:


sudo nano /boot/config.txt

edit what you need

CTRL+X answer y then hit Enter

If not try posting what steps and results you are using to produce the errors.

I had something similar
and I could not change the overscan

I restarted RPi pressed enter to go to system installer, clicked Advanced
and there's an option to edit config.txt file

I open the file with sudo nano /boot/config.txt
I can save the file successfully.
When running sudo nano /boot/config.txt again it shows me the changes I made.

However, when rebooting to make linux use the changed settings, the config.txt turns back into it's original unchanged version and all my changes are gone.

Why might that be and how can I make my changes stay?

[Bombadil]

I managed to make the changes constant via sudo chmod 444 /boot/config.txt
However I don't think that's how it is meant to be and would rather solve the issue in a more approriate way than with that dirty fix
