Hello all very new to Ubuntu, I need few things, I want to install X-Plane flight sim. I can get the demo part of this to run. I need to know where to put it. It defaults to / x-plane...where do I put it from there.
2 the above needs the latest nvidia video driver, how do I get that to run and where does it go. I am not understanding the file tree yet.

Could you point me please

Many Thanks
Steve
