I re-emerged both @x11-modules-rebuild and @module-rebuild, but it did not help a bit. Still the same problem. I assume that the key is the vboxvideo line from dmesg. It registers a framebuffer device fb0, which may cause the Xorg-driver to fail. But I do not know how to disable this, since it comes from the vbox driver module itself. Regards Alex
