I upgraded to ubuntu 11.10 and now I cannot run Google Earth or other applications that require GLX. Here is what I got when i ran unity_support_test. How do I fix this?

aurora@eurus:~$ /usr/lib/nux/unity_support_test -p
Xlib:  extension "GLX" missing on display ":0".
Xlib:  extension "GLX" missing on display ":0".

What graphics card does it have? Please add the output of lspci -nn to your question. Have you installed proprietary drivers directly from the vendor (i.e. AMD or nvidia?) – Lekensteyn Mar 9 '12 at 22:34
Updated the info. Ubuntu could not find any proprietary drivers. – Franz Payer Mar 12 '12 at 17:56
Please attach /var/log/Xorg.0.log to your question. Paste it on – Lekensteyn Mar 12 '12 at 18:28 – Franz Payer Mar 12 '12 at 18:47

It looks like you've installed the nvidia driver which breaks your graphics:

[ 37.912] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

Uninstall the nvidia-current package and restart the X server (by rebooting for example). Your laptop is supposed to have a nVidia card (Optimus though). Your BIOS is configured to use the integrated card only. If you wish to have on-demand use of the graphics card (keeping the discrete nVidia card off at other times), have a look at Bumblebee as mentioned in How well do laptops with Nvidia Optimus work?
