Comment #12 on issue 376 by daniel.wagner: TwinView issues http://code.google.com/p/xmonad/issues/detail?id=376 evvsoft: I can't reproduce your description, "xmonad show very long error". The config you pasted seems to compile and execute to me. As for your keybindings, I suggest you take a look at the "Usage" section of the IndependentScreens documentation; in particular, it has some code that you should use to override the default keybindings for mod+1-9, and that you can mimic for any other workspace-changing keybindings you may have. You may also like to use the "unmarshall" function (or "unmarshallW" if you are using darcs) to pretty-print the workspace name in your layoutHook. (I believe there is a description of how to do this in the docs if you build them from the darcs version.) Let me know if you have any more questions or annoyances.
