(EE) Failed to find required symbol 'dixLookupResource'
This occurs when trying to load the extensions on X.Org X Server 188.8.131.521 (1.7.0 RC 1).
It causes mucho breakage in that GLX fails to load and causes segfaults all over.
This breaks glxinfo, compiz and anything else trying to use the GLX extension.
This is a new error since .901 as .900 works fine if you revert. So, yet another change
for you devs to kindly fix for us, please!
