DisplayLink driver

[Alejandro Bonilla]

Hi,

I have a Lenovo ThinkVision LT1421 which I guess uses the DisplayLink
chipset 1.x, I'm also using kernel 3.11.6. The device is recognized
[  997.279496] usb 2-1.5: new high-speed USB device number 4 using ehci-pci
[  997.344494] usb 2-1.5: device descriptor read/64, error 64

[  997.640886] usbcore: registered new interface driver udl

But xrandr is not recognizing the device/screen.

So the question is, which driver supports it, the UDL or UDLFB driver?

(please cc me, I'm not subscribed)

Thanks
