Hi Ray,

Are you using the setuid version of X11 or the new non-setuid version?
And in the latter case, do you have libpam-systemd installed?

Possibly related information:
> xorg-server (2:1.17.3-1) unstable; urgency=medium
> 
>   The Xorg server is no longer setuid root by default.  This change
> reduces the
>   risk of privilege escalation due to X server bugs, but has some side
> effects:
> 
>   * it relies on logind and libpam-systemd
>   * it relies on a kernel video driver (so the userspace component doesn't
>     touch the hardware directly)
>   * it needs X to run on the virtual console (VT) it was started from
>   * it changes the location for storing the Xorg log from /var/log/ to
>     ~/.local/share/xorg/
> 
>   On systems where those are not available, the new xserver-xorg-legacy
> package
>   is needed to allow X to run with elevated privileges.  See the
>   Xwrapper.config(5) manual page for configuration details.
