[rishitells]

Hi Guys,
Whenever i want to login as "root" from the login screen. it displays a message "you cannot login as "root" from this screen. I also can't change
"Screen Resolution" from my user. Plz tell me how to login as root and change screen resolution.

u cant login as root directly for security reasons... to access root functions type sudo <command>
to disable sudo and enable root permanently type man root and follow the instructions...

~$sudo passwd root

and edit gdmsetup to "allow local admin to log in",is highly discouraged as ppl tends to browse internet and use without acknowledging the risk associated with it.
