Hello to everyone
I am new to this forum to Linux and Knoppix.
If this post is not in the proper forum please advise and I will post elsewhere.

I have a couple questions which I am not sure I totally understand the answer to which I have found on the search's which I have done. Therefore I am not to sure of my footing before I attempt to do anything.

I have Knoppix 3.3 installed on the hard drive as the only OS and would like to remove some of the programs, app or anything which I don't need.

First Question:
What problems are there in removing any extras that I don't need and what will I mess up?
Also, please advise as to the easiest way of removing the extras.

Second Question:
When logged in as root verses logged in as user there are different icons placed on the kicker and when I changed the mouse pointers logged in as root vs logged as Knoppix user the pointers are different eventhough the setting are the same.

Thanks for any advice.
Dooley
