LDM_DIRECTX=yes by default?

[monteslu at cox.net]

I found that on edubuntu 7.04 I could not get thumbdrives working on thin clients when LDM_DIRECTX was set to yes, however performance of tunneling everything through SSH was just awful. Anything with the slightest amount of animation was choppy.

I'd say make the default LDM_DIRECTX=yes, but make sure that local devices still automatically mount and popup nautilis/dolphin on the thin clients.
