I have the following problem:
Old PC -> Tried to install Ubuntu via Live-CD (12.04 / 12.10) -> as soon as the desktop starts loading I get stuck at a black blank screen. No wallpaper, no GUI, no nothing. I cannot load a terminal via ctrl + alt + F1.
I tried installing Ubuntu Server (12.04) which worked fine. After installing I did a sudo apt-get install ubuntu-desktop which led to the exact same problem as with the Live-CDs.
I am clueless as to what is going wrong here. I used ubuntu on this PC before without problems.
