Thanks for the answer, I forgot to mention that it's the same on real hardware, corei3 with intel gpu... But it's not important anymore. So no driver is loaded on startup at all? I tried `kldload vboxvideo` as root, but failed too... kldload can't load vboxvideo: No such file or directory. Could you...

I've just wanted to try GhostBSD 3.5RC on Virtualbox, but X failed and also said shared objects (libharfbuzz.so.0 and libwnck-1.so.22) not found.
