Issue 29: MergeFB "Pseudo" Xinerama not supported http://code.google.com/p/xmonad/issues/detail?id=29 Comment #2 by Ulrich.Pfeifer: I am running ion3 (old snapshot) in Pseudo-Xinerama mode on the same display. checking for unistd.h... yes checking X11/extensions/Xinerama.h usability... yes checking X11/extensions/Xinerama.h presence... yes checking for X11/extensions/Xinerama.h... yes configure: creating ./config.status % xdpyinfo | grep XINERAMA XINERAMA XINERAMA Hmm, the darcs snapshot did *not* contain the file include/X11_extras_config.h.in. I did create it as empty file. It did not exists in the last release and was required for compilation. Can that be related?
