Every time I try to edit the grub file it does not let me save it. It says "access denied" or, in a different editor:
Object not accessible. The object cannot be accessed due to insufficient user rights.
Sometimes it does not let me edit it, and this frustrates me as I need to edit it for my Wacom tablet to work.
How can I save my edited grub file? I saw a YouTube video on "Wacom on ubuntu: How to run your tablet on Ubuntu and Ubuntu LiveUSB - Wacom One" but I don't know if that works.
