I've upgraded to 10.04 from 9.10. Everything went fine until I've rebooted. After reboot, I've received some message about status panel and being sleepy, dismissed it. However, I haven't seen the user widget on Gnome Panel since that.
This image shows which widget I'm talking about. If some one has any ideas about how it's called properly, please share.
Anyway, the question is, how do I turn this panel (and ability to shut my system down without resorting to console) back?
