My system has a three monitor setup:




  1. Monitor 1 connected to the onboard i915 chip

  2. Monitor 2 & 3 connected to a Radeon RX 560 GPU


This configuration worked until I upgraded CentOS to the 3.10.0-862.2.3.el7.x86_64 kernel.



After the kernel upgrade only Monitor 1 (attached to the onboard i915 controller) is working. Monitor 2 & 3 aren't receiving a signal.



The output of lshw shows the Radeon display as -display UNCLAIMED.

The radeon module now loads during the boot process but lshw still outputs -display UNCLAIMED and the connected monitors still receive no signal.
