Because of bug #453702, I have added the various lightdm greeters as PDEPENDs with appropriate useflags. On arm and ppc not all greeters are keyworded. So please keyword those greeters, or package.use.mask the appropriate useflags that trigger those greeters on your arch. Target for =x11-misc/lightdm-1.4.0-r1: KEYWORDS="~amd64 ~arm ~ppc ~x86" current greeters and their current keywords: =x11-misc/lightdm-gtk-greeter-1.3.1-r1 amd64 arm x86 =x11-misc/lightdm-kde-0.3.1 amd64 x86 =razorqt-base/razorqt-lightdm-greeter-0.5.2 ~amd64 ~ppc ~x86 I'll leave it up to arches to decide how to handle the details.
ppc done
arm done, closing.
