Version-Release number of selected component (if applicable):
Build : RHEL-7.0-20131111.1
Steps to Reproduce:
1. connect a monitor to your machine
2. boot up the machine
3. log into GNOME or KDE
1. disconnect the monitor
2. plug in another one instead
Hotplugging results in sleeping monitor most of the time. A few time the screen lit black, but this caused it to hang.
Screen should be correectly powered on with a native resolution
You need linux-firmware >= 20131106-0.1.git7d0c7a8
This need to be retested but here i can not reproduce with :
We believe this is already fixed but moving to 7.1
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.
Hotplugging mostly works with some issues:
1. Machine will reboot immediately if DP was not plugged on boot, and gets plugged 
2. Machine will reboot immediately if DVI-I port is disconnected (at least when using analog connection)
: There is already a bug for this: https://bugzilla.redhat.com/show_bug.cgi?id=1263788
Retested with a different case.
Verified fixed in:
Most likely problem was lack of a ground connection on the backing plate.
