suspend - Frozen monitor problem in a multi monitor setup (16.04) - Ask Ubuntu


i installed ubuntu 16.04 , noticed strange behavior described below.

i have 3 monitor setup primary monitor (1) attached primary graphic card (an amd r9 270x) displayport, projector (2) attached primary graphic card hdmi, , secondary monitor (3) connected integrated chip intel i7-2600k processor hdmi.

when start system ubuntu starts normal , screens showing ubuntu logo , dynamic progress bar below. when reach login screen on primary monitor (1), still see ubuntu logo , frozen progress bar on 2. , screen frozen until (from have noticed) 2 events happen:

  • the timer "turn screen off when inactive" kicks in

    when happens screen go black, , when move mouse 3 monitors wake again, , moment on 3 monitors behaving normally.

  • i suspend system

    if suspend system, , wake 3 monitors behaving normally.

i'm looking troubleshoot error, since don't want suspend or wait "turn screen off when inactive" kick in before can use monitors.
