I am no expert, but if you have a prompt <user at hostname:$-) or a login 
prompt then AFAIK the 'system' has started OK, but for some reason the 
GUI has not and I did know a couple of commands that MAY help....

(I'll mention at this point that I'm running Saucy so some of this may 
well be obsolete, in which case please accept my apologies in advance!).

If you get a login prompt login first (obviously)

startx - this command starts the 'X-server' that powers your GUI, this 
is possibly redundant if 14.04 is using Mir (I hope not as these things 
should be tested in a development release first!)

lightdm - this command should through you to the graphical login screen 
(may need to be run as root <sudo>)

It may also be worth checking the logs in /var/log (cd into /var/log and 
use nano to view the files) I'd look in the xorg  log first if it still 
exists :)

None of this will correct the error that has left you hanging in limbo, 
but might get you a usable system!

If you are just getting a flashing cursor in the top left corner of the 
screen I know of no-way to recover the system, when it has happened to 
me I've always ended up re-installing.

As I stated I'm not a expert and if anyone has any other hints or tips 
or correct an error I have made I would be pleased to hear :) I've 
waited all day before replying to your question in the hope someone with 
more knowledge than myself would jump in first!

Wishing you good luck,


Pete S
