Hello, yesterday I had a small update on Ubuntu 12.10. After an update I turned of my Dell Vostro 3450 machine. Today I tried to turn it on, when it started I've chosen Ubuntu in my GRUB window, then I saw Ubuntu logo and after that the screen went black and the only thing I could see is the mouse cursor, which I couldn't move. My machine is using Intel HD Graphics 3000 GPU. Any ideas how to fix this problem?
