help on restoring system

[hydcozz]

Hi. First, sorry for my English. I am not very good on it.

Second, see http://ubuntuforums.org/showthread.php?t=1346815

I could login with GNOME Failsafe. But I don't know how to restore ubuntu to a previous working state.

How can I reverse the update I've done today I make ubuntu work normal again?

Thanks.
