Okay, so I've been round and round with my computer on this... I can get it to boot, I can get it to load the Text version however whenever I typed in "startx", my screen goes blank and I have to reboot, alternatively, I have tried typing in "ubiquity" without loading up the graphical interface, it gives me a few lines back and then returns to the prompt? Has anyone else had this problem?

Alternatively, I have tried BT5R2-KDE-64 as well, however whenever I try to boot into that I get read errors.

Maybe it is just Sony, but I have had Ubuntu 11.1 installed in the past and it ran very well. I don't understand why I am having such issues with this.

I do have a computer capable of running 64-bit operating systems, my Windows 7 is 64 bit and so was Ubuntu.
