root password

Hi everybody:
I have a problem. How does it possible that when I type the root password on terminal, later write:

su
password: ******

System recognize the password, but when a I use the GUI environment, the system does not recognize it.

Any suggestion. :o

Thanks in advance.

Do you mean xlogin or xterm?

Are you doing su in all cases?

Also many systems won't let you login as root if you are not on the system console.

Hi:
Yes, I did. I did in both xlogin like xterm.
Do you kwon any solution?. Because I would like to install or better said, detect LAN and shared printers in local net, and I preffer do it GUI environment.
Thanks in advance. :wink:
