I'm not really sure how this is any different than any other Ubuntu or Debian installation. Installing the required packages for multimedia playback and GIMP and such is fairly simple on any Deb/RPM based distro anyway, and its a skill that any user will have to learn at some point.
what's the "studio" for if this stuff has to be installed? Consider included some information on how to modify the color theme. I would think most creative types would want a neutral gray palette with minimal visual interference.
Ubuntu Studio does have a neutral grey palette. Modifying the color is easy, System->Preferences->Appearance.
I think it's called Studio because the Linux kernel was built with more aggressive real-time options turned on by default, to reduce jutter in audio+video capture.
My fiancee had a similar problem. I used some X.org black magic and avoided a re-install. ("Black magic" because I did not know what finally made it. The steps outlined in the blog-post did not suffice.)
