Hi and if it show root@matt then you are in recovery I believe. Use the command startx.

no actually I was in the normal mode , and I tried the recovery mode as well but the same thing appeared .

and I tried startx but that what it tells :

root@matt-desktop:~# startx
command 'startx' is available in '/usr/bin/startx'
the command could not be located because '/usr/bin/' is not included in the environment variable .
dash: startx: command not found .

any one can help ... !!

See what happens if you do a:
sudo apt-get update
sudo apt-get dist-upgrade
from the command line
