Im a linux newbie so im sorry if this question is silly.

I just installed gentoo, but for some reason im unable to login as root using the su - command.
If i press ALT + F2 or seomthing and open a new terminal, then im able to login. If i log out of the username i am using, i can relogin as root. But i am unable to use 'su -' or 'su'

What could be wrong?
Also could someone tell me how i change my screen resolution. Is it possible to change screen resolution even if all you are running is command line linux?

Thanks guys

that is because you didn't make your user part of the "wheel" group

Maybe su is restricted for normal users in the sudoers file in /etc?

This must be one of the most commonly asked questions. :wink: See this FAQ: Why can't I su to root?
