was right that a GUI isn’t installed by default on Ubuntu Server 10, and ’s follow‑up about SSH is noted. Practical, safe steps follow: install X/a desktop if a GUI is really needed, and handle root SSH with care (prefer key‑based access or using sudo from a normal account). Ubuntu 10 is old and no longer supported—upgrading to a maintained release is strongly recommended for security.

To install a desktop (full GNOME is heavy; XFCE is lighter):

sudo apt-get update
sudo apt-get install ubuntu-desktop      # full GNOME (large)
# or, lighter:
sudo apt-get install xorg xfce4 xinit   # X + XFCE; provides startx

Start the GUI from the console or via the display manager:

# start X session as your normal user
startx

# if GDM is installed it can be started/stopped
sudo service gdm start
sudo service gdm stop

If X fails to start, look for errors in the server logs:

grep EE /var/log/Xorg.0.log
tail -n 200 /var/log/Xorg.0.log
dmesg | tail

To enable SSH root login (not recommended unless necessary): set a root password, decide whether to allow password or key‑only root login, edit sshd_config, then restart SSH.

sudo passwd root
sudo nano /etc/ssh/sshd_config
# set one of:
#   PermitRootLogin without-password   # key-only (recommended)
#   PermitRootLogin yes                # allows password login (risky)
sudo service ssh restart

Better alternatives: create a normal user, give it administrative rights (use visudo) and SSH in as that user, then sudo -i to become root. After any root SSH work, revert to key‑only or disable root login to reduce risk.

RTFM. You need to install the Xorg server, tools, and window manager such as KDE or Gnome in order to have a GUI front-end for your server. As for telnet, it is HIGHLY recommended that you do NOT enable telnet on todays' systems as it is very insecure. Use SSH instead. In either case, usually it is the xinetd daemon that starts these tools (including ftp, and such), which requires editing some configuration files in /etc. Read the man pages for xinetd for information on what to do for that.
