Don't you need something faster than that??? I mean we are heading towards 4k monitors. I don't think usb can do that.

On another note a technology like thunderbolt is cool but being intel only somehow spoils it. One cable connections are cool though.

The USB 3.0 DisplayLink chips are already there, they work on a new kernel driver as well and I got the ports in the laptop... just a matter of time.

Also, this doesn't mean you cannot use the laptop display for videos, games etc. and on the external a browser window, terminal or something else open (this is how I work at the moment).

So i've built all the required bits under gentoo, and have it running. xrandr --listproviders shows me:

Providers: number : 2
Provider 0: id: 114 cap: 0 nc: 2 no: 8 nap 0 name:Intel
Provider 1: id: 65 cap: 0 nc: 1 no: 1 nap 0 name:modesetting

but I cannot figure out how to use --setprovideroutputsource <prov-xid> <source-xid> or --setprovideroffloadsink <prov-xid> <sink-xid> to do anything interesting. every time I try (and i've tried every combination I can think of) , I get either:

xrandr --setprovideroutputsource 65 114
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  139 (RANDR)
  Minor opcode of failed request:  35 ()
  Value in failed request:  0x41
  Serial number of failed request:  11
  Current serial number in output stream:  12

or

xrandr --setprovideroutputsource 1 0
X Error of failed request:  148
  Major opcode of failed request:  139 (RANDR)
  Minor opcode of failed request:  35 ()
  Serial number of failed request:  11
  Current serial number in output stream:  12

anyone else actually trying to use this?
