Problem editing grub.cfg
 

I I am moving to Linux Mint from Ubuntu. (Probably just one of thousands).
I want to edit the grub.cfg file. You know, the one that says, "do not edit this file".
With Ubuntu, I simply opened a terminal, typed in , navigated to the grub.cfg file and edited it.
But now, with Linux Mint, I type in gksudo nautilus, and a window opens with the desktop folder in it. I select file system, and boot folder, then select the grub folder. I open grub.cfg and edit the sections I want but cannot save it. I get the following outputs in the terminal:

I could use a little help here.
Thanks

This is just GTK noise. Don't do this. Learn to edit files properly in a console. stop using noddy junk like nautilus through hacks.

sudo vi /boot/grub/grub.conf

etc.

"Do not edit this file" means that your changes will be lost after some update. This file is created automatically from files in /etc/grub.d and these files should be modified or configuration file /etc/default/grub.

As for the error messages, try doing a web search using "Failed to create file '/root/.local/share/recently-used.xbel"; it seems that you can create the file /root/.local/share/recently-used.xbel to get rid of those error messages:

In your case (in Linux Mint), try sudo followed by those commands.

I appreciate the advice. Thank you very much. I'll post back when I get some results.
