Hi, I have the same problem after I hibernate/resume. I noticed:
1. The shutdown, restart buttons don't appear
2. Logout, hibernate, suspend buttons show up, but don't do anything when you click on them.
3. Software package updates (which require a root authorization) faill with an error msg saying no credentials.
Seems like this is a known bug and will likely get fixed. In the mean time are there any workarounds, other than to reboot the system from the command line.
How do i just logout/login?

Just verified this workaround fixed the issue:
CTRL-ALT-F2 followed by
(I did login in the console screen the first time I had to use this workaround).
