The GLX_EXT_texture_from_pixmap disappeared from "GLX extensions:" which is good. You say "same issue", do you still get "Failed to initialize TTM buffer manager"? Does it crash if you try to start compiz in the failsafe terminal session?
Can you please try to get a full backtrace from Xorg? See that wiki page and the DebuggingXorg link on it.
