First time ever using Ubuntu so just wanted to try it.
I downloaded the image and burnt it, booted it, and selected "Try Ubuntu". After a few mins, it loads the desktop but requires a login? O.o
I've downloaded "Ubuntu 14.04.2 LTS" (Desktop, 64bit) from the official server and the checksums match.
I've tried "ubuntu", "lubuntu", "xubuntu", "xbuntu", all with blank passwords.
Any help please?
