I have installed Ubuntu 10 last night and finished all upgrading stuff, in the time when updates are applied I downloaded a torrent file. As soon as download is finished I rebooted my system. As usual at start up it asked my login and I did the same.
After a successful login It should show me the desktop, or show an error message in case anything has gone wrong. But what I had is only a cursor and a blank wall paper.
Can anybody tell me what is the problem and how to resolve this?
