Getting X-Windows (and more) running...

[Doin' the Bull Dance, Feelin' the Flow...]

I installed Linux (Slackware 3.4) recently.  I've been playing around with
it (I truly am a newbie...), but I have one major problem...

I have two HD's...one is 340MB and one is 420MB.  I installed nearly
everything...so much so that X windows does not fit on the same HD as most
everything else.  My friend, who seems to know more than his fair share
about Linux (he runs a University web server on Linux, as well as his own
computer) told me that I have to copy only certain files from hda to hdb,
and then vice versa as well.

Now, I can't get access to my friend's brain anymore, and I need to do this
so I can get everything running....any thoughts???

Thanx in advance...
