I am not receiving the Unity 3D option when logging into Ubuntu 11.10. The only options I have are GNOME, GNOME Classic, GNOME Classic (No effects), Ubuntu, and Ubuntu 2D. I ran the test
/usr/lib/nux/unity_support_test -p . Here are the results:
OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile OpenGL version string: 2.1 Mesa 7.11 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes
I even tried the solutions mentioned at No Unity 3D Option on the login screen, but I am still not able to log into Unity 3D.
Under System Info --> Graphics the driver is listed as Intel Sandybridge Mobile and experience as Standard.
