Mint 12 not working with dual graphics heads

While Ubuntu has worked with 2 independent displays running off one Nvidia graphics card, Mint 12 is not. The driver starts up and aborts. It's supposed to be the same Nvidia driver being downloaded by both Ubuntu and Mint, yet Mint is not working. It's back to Ubuntu for me.

LTE doesn't work like that!

Having a bunch of OFDM (whether LTE or WiMax) femtocells is a terrible idea!

OFDM uses a bunch of narrow band carriers for data transport. These carriers must be allocated between transmitting sites so as not to have interference among the different transmitters, be those transmitters the base station, femtocell, or mobile. The carrier allocation needs to be under the control of the area SoftBank (for example) infrastructure - that means much more control channel traffic to/from the femtocells, base stations, and mobiles, and extra computing power for the allocation algorithm to deal with the new femtocells!

This could all go horribly wrong. With cdma it works easily, with OFDM, NOT!
