> Good to know that it works! Well, without the advices form you and Klaus I wouldn't have gone far, so great thanks:) Btw, this is not that important, but since I plan to host any OS with the wall, does OS X have any special tweaks like the windows WDDM/XPDM that I should now about? So far I've checked Windows and XFCE and they both worked fine, but Klaus arleady warned me that X11 is less resource hungry than Windows. Does OS X fall into the same category as X11?
