Using any version of dbus above 1.8.4 causes xfce4-session to fail on login with a popup error dialog which reads: Unable to contact Settings Server. Failed to connect to socket /tmp/dbus-tNwiNYuQA4: connection refused This only happens when I let the display manager start the session. If I login to a failsafe session, which is just a bare xterm, then I can manually start xfce4-session, and it works fine. If I click through the error dialog, xfce eventually loads after hanging for about 5 minutes, but with no WM, desktop or menus; just all my startup programs, like sylpheed and firefox, all bare X children of the root window. I tested with xdm and slim as my login manager; they both fail the same way, and my failsafe workaround succeeds the same way for both. Using non-dbus aware WM such as twm gives no error. Downgrading to dbus-1.8.4 fixes it. Reproducible: Always Steps to Reproduce: 1. login with xfce4 as the session manager Actual Results: failure to start xfce4-session Expected Results: successful start of xfce4-session make.conf: CFLAGS="-O2 -pipe -march=native" CXXFLAGS="${CFLAGS}" MAKEOPTS="-j32" CHOST="x86_64-pc-linux-gnu" FEATURES="userpriv usersandbox usersync" USE="-* 3dnow 3dnowext mmx mmxext nls nptl opengl openrc python sse sse2 sse3 ssse3 sse4 sse4_1 threads vaapi vdpau" PYTHON_TARGETS="python3_4 python3_3" PYTHON_SINGLE_TARGET="python3_3" USE_PYTHON="3.3 2.7" LINGUAS="en ja" GENTOO_MIRRORS="http://gentoo.mirrors.tds.net/gentoo ftp://gentoo.mirrors.tds.net/gentoo http://gentoo.mirrors.hoobly.com/" VIDEO_CARDS="radeon radeonsi" INPUT_DEVICES="evdev" PORTDIR=/var/cache/portage/tree PORTDIR_OVERLAY=/var/cache/portage/overlay PKGDIR=/var/cache/portage/packages DISTDIR=/var/cache/portage/distfiles emerge --info: Portage 2.2.8-r2 (default/linux/amd64/13.0, gcc-4.8.3, glibc-2.19-r1, 3.16.5-gentoo x86_64) ================================================================= System uname: Linux-3.16.5-gentoo-x86_64-AMD_Opteron-tm-_Processor_6366_HE-with-gentoo-2.2 KiB Mem: 131924948 total, 130869852 free KiB Swap: 0 total, 0 free Timestamp of tree: Sat, 25 Oct 2014 16:00:01 +0000 ld GNU ld (Gentoo 2.23.2 p1.0) 2.23.2 app-shells/bash: 4.2_p53 dev-lang/perl: 5.18.2-r2 dev-lang/python: 2.7.7, 3.3.5-r1, 3.4.1 dev-util/cmake: 2.8.12.2-r1 dev-util/pkgconfig: 0.28-r1 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.12.4 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.13, 2.69 sys-devel/automake: 1.11.6, 1.13.4 sys-devel/binutils: 2.23.2 sys-devel/gcc: 4.8.3 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4.2-r1 sys-devel/make: 4.0-r1 sys-kernel/linux-headers: 3.13 (virtual/os-headers) sys-libs/glibc: 2.19-r1 Repositories: gentoo james ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=native" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -pipe -march=native" DISTDIR="/var/cache/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_CA.utf8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j32" PKGDIR="/var/cache/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/var/cache/portage/tree" PORTDIR_OVERLAY="/var/cache/portage/overlay" USE="3dnow 3dnowext amd64 mmx mmxext nls nptl opengl openrc python sse sse2 sse3 sse4 sse4_1 ssse3 threads vaapi vdpau" ABI_X86="64" ELIBC="glibc" INPUT_DEVICES="evdev" KERNEL="linux" LINGUAS="en ja" PYTHON_SINGLE_TARGET="python3_3" PYTHON_TARGETS="python3_4 python3_3" USERLAND="GNU" VIDEO_CARDS="radeon radeonsi" USE_PYTHON="3.3 2.7" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, SYNC

Oh, wow. I feel like a tool now. I was missing USE="X" on dbus. I noticed this when I proofread the files I attached, and saw that I had it on, but for an exact version, in package.use. Once I added it back in for 1.8.8 it worked fine. Not sure why <= 1.8.4 was ok without the X USE flag though. Sorry for the noise.
