Osteonectin ; Hi !
I expect that what you see is a command line prompt in tty1..
Lets see what happens when you log into your system, and try to get the GUI started.
at the prompt type your normal username and hit the enter key.
next will ask for your password //enter that...
prompt is waiting for next command enter:
and password again....
sudo service lightdm start
I expect/hope your desktop is started.
If so we will re-install your desk top. Please advise on the results of the above>
