edit the fstab file
 

How do you edit the fstab file . when i try to save my changes to the fstab file i get the msg can't save need root permmision. How to to be in the root permission while in GUI text editor. so that I can save my changes.

Well, a few ways:

1. Log in as root on your machine and edit fstab
2. Open a terminal screen in your user account, su to root privileges and run gvim /etc/fstab
(or wherever it hides on your system) in that terminal.
That would pop up Gvim with root priviliges, with fstab in it. provided you have Gvim ofcourse.
you can use your editor of choice as well like that.
