Screen Size

Mon Oct 29, 2012 2:19 pm

hey guys been playing with the pi but the screen spills off the screen both left and right, i cant seem to change this i have found the config.txt file with the overscan values in it but it will not let me save any changes to that document.
As you might be able to tell im a bit of a n00be when it comes to this and am trying to self teach the basics (and doing badly) so if you could make any replies easily understandable by a 2 yr old i may just be able to keep up.......

cheers

You say you can't save the file once edited. Perhaps that is a permissions problem.
The "pi" user does not have permissions to do this - you have to do it as root.

You can get around this by using the "sudo" command to run the command as root.
Try:
sudo nano /boot/cmdline.txt

edit the config.txt file with
sudo nano /boot/config.txt
you have to do it with root
