When I run bitcoin-qt on Ubuntu 12.04, I see this:
As you can see, there is no menu on the top menu bar. There is the "beginning" of a menu with the word "Bitcoin" but there are no "File", "Settings", or "Help" menu titles. Clicking on the word "Bitcoin" in the menu bar does nothing.
According to this it seems there should be a menu.
How do I get the menu to work?
