RX460 + MST Hub on Ubuntu 16.04

Hi,

 

I installed the latest driver from AMD 16.60 379.184 on my RX460 running Ubuntu 16.04.2, it is working fine I can get the display at full resolution on each interfaces.

 

I am using an MST hub from Startech (MSTDP123DP)1DP to 3 DP and I am trying to use extend display on all of them. I can get all 3 DP monitors working @1080p but it only works as a splitter.

 

Is there anyway on ubuntu to configure the monitors as extended on the MST hub (similar to eyefinity)?

 

Note it doesn't work on windows 10 ... cannot get 3 monitors working at the same time

 

Cheers.
