I find that my Acer Aspire One D270 Netbook (Intel Atom CPU, 2GB DDR3 memory) shows a blank screen with a blinking cursor if I tried booting 12.10 from the bootable USB stick. In fact once, I clicked the "Try from CD" button, saw the blank screen for a while and had dozed off for an hour only to wake up and see the same blank screen again.
Then I installed it alongside my Ubuntu 12.04 (64-bit OS) and on booting 12.10, the same blank screen shows up and keeps me indefinitely waiting, until I run out of patience and press the power button, restart and boot my 12.04.
How do I correct this?
Here's what I found the last few lines to be, on scrutinising the problem via CtrlAlt1 as our friend here suggests:
