Issue 29: MergeFB "Pseudo" Xinerama not supported http://code.google.com/p/xmonad/issues/detail?id=29 Comment #5 by SpencerJanssen: As you may realize, I suspect that this is a build issue rather than a problem with the code. I've just added a little diagnostic support in X11-extras, please upgrade and run: ghc -e 'Graphics.X11.Xlib.Display.openDisplay "" >>= Graphics.X11.Xinerama.xineramaQueryScreens' ghc -e 'Graphics.X11.Xinerama.compiledWithXinerama' Try this from a brand new 'darcs get' of X11-extras, to rule out the possibility of any old configuration bits causing problems. If this isn't a build issue, I'm not sure what's going on -- the C code you've posted seems equivalent to the code currently in X11-extras. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
