Root loging via GUI in Ubuntu

I'm writing this post since I have a problem of remembering this every time when I wanted to use it. I think this would also help you.

To get the root through GUI

1) You have to press

alt + F2

it will open dialog box called 'Run Application'

2) then you type

'gksudo nautilus' without quots

in the text field and then Ubuntu will ask for your Password.

3) type the password

then you will get the window with '/root'
where you have all admin rights

Note:
In this mode there won't be any warning when deleting or modifying files which will get you in to trouble even if you accidentally deleted or modified admin files. Therefore be careful and do not use this mode unless otherwise it's really needed.
