Comment #4 on issue 432 by kubaracz...@gmail.com: Module for linking workspaces in a multihead setup http://code.google.com/p/xmonad/issues/detail?id=432 Ah yes, good.. Sorry for the X.StackSet, had it imported as W However I get " Couldn't match expected type `X ()' against inferred type `W.StackSet WorkspaceId l a s sd -> W.StackSet WorkspaceId l a s sd' In the first argument of `switchWS', namely `W.view' In the expression: switchWS W.view message In the expression: (switchWS W.view message, 0) " which i don't understand ;( What I did is I set: messages = defaultMessageConf which should use noMessages (if I am correct). This, however brings the said error... Any idea about this?
