Do the following commands, all seperated by pressing Enter (you probably could have figured that)
Enter your root password when prompted, then hit Enter.
Then:
Code:
apt-get install x-window-system
...and let it go. Once that is done, you will need to decide what window manager you will want, whether it be
KDE or
GNOME or possibly something else.
If you decide to get KDE:
Code:
apt-get install kde
or for GNOME
Code:
apt-get install gnome
Remember you must be su to do apt-get.
Good luck, and if you have any problems, let us know.
