I am running ubuntu 13.10 on a desktop system and I have 2 monitors that I am trying to connect via Displayport's 1.2 multi-streaming support.
The system is equiped with an Intel Core i7-4770K processor and I'm using the displayport (1.2) output of the Intel HD Graphics 4600 to connect the computor to a Dell U2413 monitor. The second monitor (Dell U2412) is connected via a displayport 1.1 cable to the Dell U2413 monitor.
Ubuntu detects the U2413 monitor fine, but it doesn't detect the U2412 monitor. (The U2412 monitor is only recognised when I connect it directly to computor.) The daisy chain setup works fine under Windows 7 though … Any ideas on how to get it working under ubuntu?
