[tex-live] Where is the root dir of my Tex Live installation

With compatibility I meant for all, that the same components are 
installed on both my computers, so that a document should be rendered on 
both sides almost identically without additional installation of 
software components.

That there are a lot of other compatibility problems too, I can see also.

Important question for me now:
How can I deinstall the existing versions of TEX on my Ubuntu machine?

I want to reinstall with the Tex Live dvd from tug.
A new install over the net is lasting to long with my slow internet 

How to deinstall?
