Bought a German keyboard by Cherry for use with a Ubuntumedia 16.04. Could not get the keyboard to produce the proper letters such as the U with the umlauts. The keyboard is a Cherry RS 6000 USB ON and is not listed as such in Keyboard app. It is a QWERTZ not a QWERTY. It behaves as a standard keyboard but the special symbols don't work. I would like to use it in retyping some old Finnish pamphlets. Thanks.
