I was searching for login screens like mac and I got this one
I did everything correctly and suddenly I was told to edit
I opened the file in gedit and I changed it but I couldn't save it - I got the error "you do not have permission to edit this file". I saw from the permissions that only root has permission to edit it, so I ran
which logged me in as root, but I was still not able to complete the edit.
How can I edit and save this file?
