I've installed xorg, which works fine, and gnome-light.
So I wanted to boot with gdm and not xdm. I've changed /etc/conf.d/xdm and /etc/rc.conf. I even did a

But my laptop kept booting with xdm. So I read I needed to install gdm, therefore:
but something went wrong...
emerge: there are no ebuilds to satisfy "virtual/mta".
(dependency required by "app-admin/sudo-1.6.9_p16" [ebuild])
