After upgrading from 11.04 to 11.10, unity desktop icons do not get keyboard focus. As a result, can no longer rename or delete files from the desktop view, and any keyboard input continues to be directed to the last application with focus, e.g., a text editor.
The text control under each icon receives mouse focus but not keyboard focus, so is not editable, i.e. F2 or selecting 'Rename' from context menu has no effect. As you would suspect, with mouse focus on a desktop icon, the delete key has no effect.
How to repair this please?
