No. Changelog sent from apt-listchanges:

xserver-xgl (1:1.1.99.1~git20070727-0ubuntu2) gutsy; urgency=low

  * debian/xserver-xgl-notification.update-notifier
    + Inform users that we start Xgl automatically, so previously set
      up Xgl sessions may not work correctly.
  * Remove old Xsession.d file on install, if it hasn't been modified
    (LP: #136962).  New Xsession.d file won't fall over after
    xserver-xgl is uninstalled.
  * debian/00-xserver-xgl_start-server
    + Split into a wrapper script debian/Xgl-session, and install this
    into /usr/bin and a much smaller debian/98-xserver-xgl_start-server
    file.
    + Install Xsession file to 98-xserver-xgl_start-server, so that it's
    at the top of the $STARTUP stack instead of starting Xgl first in
    the Xsession.d process.  Fixes startup for those who manually
    installed the fglrx drivers (and possibly others).
  * Add a killswitch to disable Xgl on a per-user basis.  If the file
    ~/.config/xserver-xgl/disable exists, Xgl will not be automatically
    started.  Documented in README.Debian. (LP: #136878)

Default for me: 
ps x|grep -i xgl
 4079 pts/0    S+     0:00 grep -i xgl
 8342 ?        SL   193:06 Xgl -accel xv:pbuffer -accel glx:pbuffer :1
-nolisten tcp -fullscreen -br +xinerama

I have an ATi card, maybe that makes a difference.
