When opening control center, second monitor goes way
Last modified: 2015-09-14 20:13:11 EDT
Description of problem:
When I open the control center my second monitor goes away. Disconnecting the cable and reconnecting doesn't make it come back.
It seems to be something related with the mini DisplayPort with the adapter and the on board HDMI.
The on board HDMI port gets disabled, only the monitor connected to the HDMI on the mini DisplayPort adapter seems to work, after opening the control center.
When it starts it's okay, got both displays, just when I open up the control center, does it disappear.
Version-Release number of selected component (if applicable):
Name : control-center
Arch : x86_64
Epoch : 1
Version : 3.16.2
Release : 1.fc22
Steps to Reproduce:
1. Open control center from the menu
Opens the control center and disables HDMI port
Open the control center
4th Generation Intel i7 4770S
Instead of opening g-c-c, do you see the same behavior if you just run 'xrandr' on a terminal?
I've replaced one of the HDMI cables, and it seems that could be the problem. It doesn't turn off the screen anymore when I go in the control center.
But I've tried the cable on another PC and it works fine. Strange behavior.
I'll leave it with this hdmi cable and see what happens, if it's reproducible.
It's probably just the cable. But odd, that it works. The other machine is also running fedora so if anything comes up, I'll re-open the bug.
