I am using Ubuntu 11.04 (Ubuntu Classic). Recently my computer ran out of battery and when I plugged it in about an hour later I now have no icons, a black screen, and my file manager won't start (isn't responding). A similar thing happened yesterday and I used the command "killall nautilus" and everything appear again. Now that doesn't even work. If I run the in safe mode all the icons and things are there, but my file manager still wont' start. Any help would be great!!! Thanks!
