ssh -X into the machine and make sure X is allowed.
I am using SL 6.x, works good.
LDM is too easy to set up (although there are some gotchas) to not use.
Basically, stop thinking about how to do the install and slavishly follow
the LDM installation instructions. Leave your brain at the door; the
instructions were written to allow ANYONE to get it going. There are some
things to look at in the pqact.conf file, but better still, use the one
Gempak creates for you.

“Big whorls have little whorls,
That feed on their velocity;
And little whorls have lesser whorls,
And so on to viscosity.”
