My Samsung x125 laptop was upgraded from Natty to Oneiric with not a lot of problems resulting, however one thing really stands out. The computer had 2 user accounts, my wife has one and so do I.
I expect: going to the name on the upper right side of the panel, and choosing the other name, and being able to change user.
When the other account is chosen, it does not accept input in the password box. To make matters worse, I can no longer return to the initial account, and a restart is the only option.

Any tips?
