Ubuntu was working fine. I upgraded to 11.1. The Launcher is no longer visible, nor does moving the cursor to the left window margin work, nor does Alt-F2 help, etc. However, when I login as GUEST, the Unity interface appears to be correct and as expected All this leads me to believe that the problem is due to a (probable) config option.
However, at this time, I am trying to learn Ubuntu and am quite unfamiliar with the system and all associated jargon, so I need a very simple, step by step explanation. Thanks.
