Since you are using a musl profile, please use the musl overlay. See https://wiki.gentoo.org/wiki/Project:Hardened_musl It has a patch for the very problem you are experiencing: https://cgit.gentoo.org/proj/musl.git/tree/x11-base/xorg-server/files/xorg-server-1.14.3-musl.patch I've sent the patch upstream, but should probably resend it: http://thread.gmane.org/gmane.comp.freedesktop.xorg.devel/44851
