I upgraded from 12.04 to 12.10 last night. It all seem to be okay, asked me to restart my computer. The Ubuntu splash screen displayed and then the computer seemed to do dormant. I thought it was part of it deleting some of the packages. After leaving it an hour, in that state, I rebooted it and the same thing the splash screen displayed as if to load and then the display went into standby and no desktop showed. I used disk boot repair and it told me to reboot, still the same but generated http://paste.ubuntu.com/6437705/. A bit lost now, only been using Ubuntu a few weeks so do not have much knowledge of terminal etc. Please help before I lose interest in Ubuntu.
