Displaying Math Equations in lyx

[Matthew L. Fidler]

I'm trying to display greek math equations under Mandrake 8, and instead of 
displaying the greek characters, said characters disappear, and I get nothing 
until output.  

I suppose that I can still deal with this issue, since the output is fine, 
but having to look at the output to see the actual alpha or beta characters 
is very cumbersome.  I was wondering if it was a font issue, or something 
else that I could fix.

Matt.
