[Libdlo] [ANNOUNCE] displaylink-mod-0.3(alpha) (was udlfb)

[jasonlife]

Samsung monitor doesn't show anything. Led in the power button just blinks..
It seems no input at all.

I can start X clients on both screens, so X started with two screens
properly.

I helped "muchman" to setup his dual screen monitors, so I hope I also have
correct X configuration ;)

What is the relation between libdlo and udlfb (displaylink-mod) ?
