I've been using windows since 3.11 and have used every revision since.......linux on the other hand I've just installed (without knowing *zip* about it) mainly in the hope of moving to this OS once I've got my feet dirty.

I've installed RedHat 7.1
how in gods name do I start X?
What is X?

My guess is X is a gui for RedHat....but anyone who can stop laughing long enough to help me with this question I would be much indebted to. ???
