My system boots up as far as the login screen and then hangs just after it reaches it.
It doesn't freeze immediately, I can still move the mouse cursor for a second or two before it locks up. It does freeze before it loads my login screen image though. It just displays the standard purple background with the white dots instead.
Restarting just throws up the same problem again.
I'm running stock 13.04, I update whenever the systems suggests I do so I should be running the latest updates. I believe I do have the proprietary graphics drivers (Radeon HD 7000) installed. I also elected to encrypt the harddrive when I installed Ubuntu orignally (not sure If that has any bearing on things). Everything had been running fine until now.
I tried using the answer from 13.04 - Logon screen frozen. When I select "Network" it prompts me with "Continuing with remount your / filesystem in read/write mode and mount any other filesystems defined in /etc/fstab", I click "Yes" and it outputs some text and then freezes forever
I'm not sure if that's related to my login woes or random weirdness. Regardless, here's the output when I click Network:
