That helped. It was telling me that GLX cannot be used with Composite 
extension enabled. Well, I was assuming the by commenting out the 
Composite extension in xorg.conf file I could prevent it from being 
enabled. Turns out that I have to explicitly disable it in xorg.conf 
file. So using
Section "Extensions"
          Option     "Composite" "Disable"
  EndSection

worked. Thanks.
