First, I am sorry for the multiple threads I have started... it just seems like the last few set up details have been an absolute battle. And Im sure they are all freaking simple! Kind of embarrassing actually.
So I am trying to rotate Retropie forma cocktail cabinet. I go into the boot/config.text and add the line "display_rotate=2" from my text editor..attempt to save and I get a Permissions denied code 3 message?? This is a new one for me.
I have tried to adjust settings in the Options > Preferences but whatever I do does not seem to work.
Asking for help....again.
Thanks

Well I've not mucked with the actualy boot/config.txt to rotate the screen vertically..that's new to me :)
But Ican edit it and make it fit and work on a real and old CRT TV :)
I have to ask are you using:
sudo nano config.txt
you have to be root to even edit that file for obvious reasons. You don't want just anybody editing that file..it might make your pi not boot or other bad things.
I assume you can access it remotely...if not..I would suggest editing it right there "locally"
That is with attractmode exited and a keyboard plugged into the pi
type
cd /boot
then
sudo nano config.txt
make your changes and then save..then reboot your pi with
sudo reboot
if you still get an error..it might be because it is mounted as a read only file..thus no changes..even if you are root.
You'll have to unmount and remount it as read/write..do this ONLY if the above does not work..you can screw things up here!
I am not responsible for any loss, damage, or heartbreak..you do this at your own risk!
sudo mount /boot -o remount,rw
after making changes as..then
sudo mount /boot -o remount,ro
then
sudo reboot
All the above can be done via ssh or with a keyboard attached.
