That looks more that your xserver is not starting instead of your whole server. Isn't it?

Do you get a shell? What do you see on your screen?


 dpgk-reconfigure xserver-xorg

to reconfigure your xserver.

Have a look in your logfiles

 tail -200 /var/log/syslog


tail -200 /var/log/Xorg.0.log

for any hints what exactly is going wrong.
