This is a known problem (or at least I heard something similar
before). You start your session when you log in, but then with startx,
that is lost in some cases because, technically, a VT session is
different from a X11 session (Wayland will take care of this, and many
other things). When you start your DE with gdm or lightdm, this
doesn't happen, because they talk to systemd (logind, actually) so
your session gets transferred to the X11 one. Supposedly, the Xfce
session manager (via startxfce4) has support for this, but only if
compiled with --enable-systemd, which is in turn supported by our
ebuilds.

So, a couple of questions:

  • Do you compiled xfce4-session with the systemd USE flag?
  • What do you have in $HOME/.xinitrc? I *think* it should just be
"exec startxfce4", if you used the systemd USE flag.
