I come from here: Xubuntu half screen is distorted upon regular boot

The problem is that the grub file is read-only and has no write permission, this : How to edit GRUB file at /etc/default/

Suggests using gksu, but i dont have internet to install gksu, what can i do? Ps: i am in root and used nano and vi

What of nano, vi? Nano is way easier to use! – George Udosen Jun 09 '18 at 16:27
It doesn seem to matter, i guess my problem exactly is "how to get write permissions for /etc/default/grub" – EricTalv Jun 09 '18 at 16:30
ok, run ls -l /etc/default/grub and lets see the write permission status – George Udosen Jun 09 '18 at 16:31
-rw-r--r-- 1 root root 1237 <-- is the response – EricTalv Jun 09 '18 at 16:33
Now how did you get to know grub was read-only, as the permission on grub looks ok? – George Udosen Jun 09 '18 at 16:34
Did you try the solution offered you in your original issue – George Udosen Jun 09 '18 at 16:37
Well if i do (in root)-> nano /etc/default/grub -> already its saying : " no write permission" and if i still were to edit i get this : " modifying a file which is not locked, check directory permissions?" – EricTalv Jun 09 '18 at 16:38
Well to even solve my original issue i have to edit grub but as u can see i cant – EricTalv Jun 09 '18 at 16:41

If you're editing through recovery mode the drive is probably in read only mode. You will need to remount the drive as read write before you edit the file. sudo mount -o remount,rw / – Terrance Jun 09 '18 at 17:06
@Terrance If your comment was written up as an answer I believe it would be useful to future users with the same issue.. – Elder Geek Jun 09 '18 at 19:53
