Black background and no menu when xfce starts. The 4.0.5 version works fine though (of xfce, not just the desktop).
Additional information: I compile with debug flags, and it seems to start and register the mouse clicks (no errors reported). xprop -root seems to be the same as on another working machine. Is the order if the window ids in _NET/_WINDOW_CLIENT_LIST(WINDOW) important? xlock -inroot works when xfdektop is not running.
It seems to be an install issue. The backdrop_settings.so is never created, but only a backdrop_settings file (missing the .so extension). Renaming this file fixes the problems.
There is the same naming problem with libxfce4_desktop_menu.so in the modules directory and in the panel-plugins directory. Not sure if its a Makefile issue or a gentoo issue.... edited on: 05-09 19:39
this is a libtool issue. please either update your libtool or, if you can't update for some reason, rerun autogen.sh in the xfdesktop directory, though that may create other problems.
