It turns out I need an older version of xfstools, so I need the older version of Ubuntu. So I made a dvd from the 10.0.4 .iso, and used nomodeset to avoid the black screen for the installer. This works -- but only til it gets to the desktop. Then the screen goes black, just before it hits the desktop screen.

I've also tried this with 11.10.

Does anyone know the solution for earlier versions?
