Displaylink udl no xubuntu 13.10

Question

Estou usando o Xubuntu Saucy Salamander (13.10).

Estou tentando conectar o monitor sem fio DisplayLink à minha máquina Linux.

• Minha configuração é

  Nvidia GT310M
  Intel HD Graphics for 1st gen i5 processors
  [with Optimus graphics - bumblebee]
  

• E uname -r é 3.11.0-12-generic

• E dmesg me fornece

• E lsmod | grep udl me dá

  udl                    24626  0 
  drm_usb                13134  1 udl
  syscopyarea            12529  1 udl
  sysfillrect            12701  1 udl
  sysimgblt              12640  1 udl

  drm                   296739  5 udl,i915,drm_usb,drm_kms_helper
  

• No entanto, xrandr --listproviders só me dá

  Providers: number : 1
  Provider 0: id: 0x47 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 5 associated providers: 0 name:Intel
  

Além disso, apenas 1 framebuffer ( fb0 para Intel) está registrado.

Como posso resolver este problema? Obrigado.

P.S. O dispositivo é baseado no chip DL-125 .
