Is that a system with 2 graphics cards? If so, the following makes google earth work for me:
As that page mentiones, you could always try experimental drivers, although that alone didn't solve my problems.
Open a console and type:
or, if you're feeling lucky, the latest-but-less-stable:
then update the drivers
apt-get install nvidia-current ppa-purge
and update /etc/X11/xorg.conf
Note that the last step breaks my system. I have restore the old xorg.conf to make it work again:
cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf
The 'driver' line in the 'device' section is what's giving me problems.
