After installed Ubuntu 11.04 Natty Narwhal, one thing you might want is to install Google Earth. Follow is how to install Google Earth 6 from google official site and fix the bad looking fonts problem.

Install Google Earth from google official site

Fix ugly, unreadable fonts

I just ran the Google Earth 6 in Ubuntu 11.04 64-bit, and its fonts looks ugly. See the picture:

I found an easy way to fix it on official help forum that is to install the MS TrueType font package:

sudo apt-get install ttf-mscorefonts-installer

then, logout and back in.
