I am using an Intel based Acer laptop and the first time I installed Kubuntu 12.10 I got a blank screen. After this I tried Ubuntu 12.04 but the result is the same.
I tried many times but the result is frustrating. If I am connected to an external screen I am able to see my screen on an external device.
I have also tried with F6 and selecting kernel but it does not work. I have tried several options but I am not able to boot my system.
I do not have any operating system, earlier I was using Windows 7 but now I am trying to install only a Linux based operating system.
