I booted up Ubuntu and have a background but no panels. Everything else seems to work fine, I can get into terminal and run Firefox for instance. I can create folders on my desktop, etc.
I'm new to Linux so was kind of just guessing to figure out what to do, I tried launching gnome-panel:
$ sudo gnome-panel gnome-panel: error while loading shared libraries: libcanberra-gtk.so.0: cannot open shared object file: Input/output error
Reinstalling gnome-panel doesn't help. I noticed I get the same error on anything I do:
$ gksudo firefox Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra-gtk.so.0: cannot open shared object file: Input/output error
Yet Firefox loads. Any ideas? I'm assuming "panel" is the correct word, what I'm talking about is the bar at the top where you can launch applications from.
