This all works for me until i get to the -setprovideroutputsource section

root@rome:~# xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x6e cap: 0x0 crtcs: 3 outputs: 2 associated providers: 0 name:modesetting
Provider 1: id: 0x205 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

root@rome:~# xrandr --setprovideroutputsource 1 0
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 ()
Value in failed request: 0x6e
Serial number of failed request: 16
Current serial number in output stream: 17

i have a dell inspiron 7737 which does does ndivia optimus, is that preventing the setprovideroutputsource ?

i have both a usb3.0 and usb2 displaylink device and the latest drivers from display link (evdi) and udl , udlfb doesn't work either.
