I just bought a ASUS X53S. Everything works flawlessly except that I can't run Unity 3D on it because NVIDIA Linux drivers currently doesn't support Optimus. So I'm stuck with the other integrated Intel Graphics Adapter. I'm already installed BumbleBee but it doesn't help with Unity 3D thing. Will the Xorg driver ever support OpenGL and especially GLX_texture_from_pixmap so that Unity 3D will work with it? The Intel driver is really snappy with Unity 2D and seems to support most other X acceleration features such as smooth scrolling.
