Using ubuntu 7.10 on an older machine.
Google earth on the windows partition works great. On Linux it will not work.
I have not been able to find drivers for linux. Can I use my windows drivers somehow?
Linux can't use drivers made for windows because the way the drivers are made is totally different. As far as I know there is no official driver from ATI to 7000 series of radeons for linux.
The default driver is about as good as its going to get. It might be using a generic driver right now and you just have to enable 3D on it (or a specific driver for it).
Last time I used Ubuntu it picked the correct driver out right away so there was no need to adjust.
