--- Comment #2 from Marek Olšák maraeo@gmail.com --- Yeah, the "server glx extensions" don't list GLX_ARB_create_context, so there is no way to create the core profile even if the driver can do it.
Also, if you want MSAA visuals, you must install the driver and restart the X server. Only then glxinfo will print the visuals.
