Rdesktop connect to opensuse, < > Key without function

Hello all. We have running one xubuntu VM on VMware. On this Desktop System 12.03 32 BIT we connect us through x2go.
From this System, we go to by rdesktop to an opensuse vm. But there, our <> key does not work. It is an opensuse VM.

The keyboad layout is german, 105 Keys.

Any Idea?
