Hi There,

I have a displaylink usb adapter which i have been trying to get working 
with my setup for a while.

when i run

 > xrandr --listproviders

i get the output

 > Providers: number : 2
 > Provider 0: id: 106 cap: 0xb, Source Output, Sink Output, Sink 
Offload crtcs: 2 outputs: 4 associated providers: 1 name:Intel
 > Provider 1: id: 68 cap: 0x2, Sink Output crtcs: 2 outputs: 3 
associated providers: 1 name:modesetting

and after running the command

 > xrandr --setprovideroutputsource 68 106

I get 3 new outputs added to xrandr:

 > LVDS-0 disconnected
 > VGA-0 disconnected
 > HDMI-0 disconnected

however they are all showing as disconnected, even though i have the 
screen connected to it and it has created the framebuffer devise 
/dev/fb2 and green is displayed on that screen.

Much help would be appreciated,
