I have a HP USB Graphics Adapter using the Displaylink technology Model NL571AA
When plugging in the adapter to Ubuntu Natty 11.04
The display link drivers are in the kernel and I loaded
xserver-xorg-video-displaylink
As the idea behind Ubuntu is plug it in and it 'just works', this bug. All the
pieces are there to have this 'just work' but it doesn't.
the kernel recognizes the device and reports it capabilities correctly:

Unfortunatly the screen just shows green when plugged in. I have
experimented with custom Xorg.conf's without success. Although the new
Ubuntu without Xorg.conf, this should not be necessary.
