I have just upgraded from 11.10 to 12.04, and at my first login, I typed in my password, and then a quick console screen showed that some
mountall event failed.
Indeed, I had some networked filesystems with mounting point
/home/here that seemed to no longer exist, creating the problem. So the screen shortly turns black and the system gets back to the login screen, playing the drum sound.
Alternatively, when I log in from e.g. tty1, I have a
No directory, logging in in with HOME=/ message.
Did I just loose all my data? Is there a way to get back to my home and data?!
