<span class="quote">> Connecting all 3 displays to a desktop IVB (i7-3770) doesn't work reliably.
> Results range from image corruption (by shifting), to never waking up one of
> the displays (always the one on DisplayPort in my tests).
>
> Xrandr shows all displays as connected, with the correct resolutions.
>
> Changing the on/off state of a single display causes all to flicker, unlike
> with 2 displays.
>
> In the case of all 3 screens being active (when all available at boot - some
> corrupted), using xrandr to turn off and back on the one assigned to CRTC2
> fails on enabling.
>
> Switching between VTs works for one cycle Xorg -> tty -> Xorg. Following
> attempts leave the screens blank.
>
> Unfortunately, I don't have access to the logs right now.
>
> Configuration tested:
> CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
> Motherboard: ASRock H77 Pro4/MVP
> Displays: DP (DVI) + DVI + VGA
> OS: Fedora 24
> Kernel: 4.8.8-200.fc24.x86_64</span >
