    Ubuntu 14.04.02 won't start up anymore after reinstalling lightdm. Black screen

    So I had some issues with ubuntu, my ubuntu won't start up properly I had to type my password twice, first it was a weird log im screen with no data, no option to power off. Second log in screen was normal.

    This is due to pc crash while having graphic card enabled, playing minecraft while not connected to power grid, i mean playing on pc battery.

    So i looked up on the net and the most frequent feedback was reinstalling lightdm with the command:

    sudo apt-get purge lightdm && sudo apt-get install lightdm

    Everytime when I had an option I choose for lightdm over kde.

    Now I cant log in anymore my pc starts up and black screen. The only function thats working is alt ctrl f1 etc.
