Its apparent that some people dont want GDM (they dont want the hassle of having to login each time)... so this one's for them! I've written a tutorial which details how to (essentially) bypass GDM. While GDM is still loaded, it basically automatically logs in "gentoox" after 1 second. GDM can never be fully disabled as it is used to call the xbvinit script now. You can find the tutorial here!
