Issue 29: MergeFB "Pseudo" Xinerama not supported http://code.google.com/p/xmonad/issues/detail?id=29 New issue report by Ulrich.Pfeifer: The current code does only support real Xinerama Screens. If the setup is a MergeFB one with Pseudo Xinerama Screens, it is not detected. The following C-Code does find the rectangles (should also find the rectangles in real Xinerama mode): if(XineramaQueryExtension(ioncore_g.dpy, &event_base, &error_base)){ xi=XineramaQueryScreens(ioncore_g.dpy, &nxi); if(xi!=NULL){ for(i=0; i<nxi; i++){ { fprintf(out,"Xinerama screen (%d,%d) %dx%d\n", xi[i].x_org, xi[i].y_org, xi[i].width, xi[i].height); } } } } What steps will reproduce the problem?

I complied x11-extra and xmonad straight from the darcs repository.
