The reason I was looking for i965_dri.so was because of two error messages in Xorg.0.log saying it could not load i965_dri.so and swrast_dri.so. For some reason crocus or iris dri's do not get loaded. My graphics are reported as Intel HD Graphics 530 in a Dell Optiplex 7040. Glxinfo does not report direct rendering as yes.
Ok so I tried copying i965_dri.so and swrast_dri.so from my tc13 installation over to my tc14 installation in/usr/local/lib/dri/ and restarted from prompt....and it seems to work with no error messages in Xorg.0.log. Glxinfo now reports ...direct rendering as yes. All seems to work....strange.
