My shadow branch PPA is now obsolete because the code was committed upstream. So now you only need xorg-edgers and the xorg.conf changes to enable a shadow buffer.
Jean-Marie, do you observe the glxinfo-triggered segfault if you remove my shadow branch PPA and switch the xserver-xorg-video-intel package back to the version in xorg-edgers? You can select the package in synaptic and choose 'Package -> Force version' to change back.
If you still experience a crash from glxinfo after making that change and restarting, then go ahead and file a new bug for it and post the link here, and I'll take a look at it.
