My Xorg.log says AIGLX is disabled in one section, but then
also says later on:

   ...
   (II) Initializing built-in extension COMPOSITE
   (II) Initializing built-in extension DAMAGE
   (II) AIGLX: Loaded and initialized /usr/local/lib/dri/swrast_dri.so
   (II) GLX: Initialized DRISWRAST GL provider for screen 0
   (II) intel(0): Setting screen physical size to 303 x 190
   ...
