[Updated] Multi Monitor setup broken after CentOS 7.5 upgrade - [AMD/ATI] display unclaimed

Post by linuxnewb » 2018/05/14 05:21:33

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.

Code: Select all

     $ sudo lshw -c video

lspci | grep VGA shows both the onboard GPU and the Radeon:

02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 550 640SP / RX 560] (rev cf)

lsmod | grep radeon returned nothing so I created a /etc/modules-load.d/radeon.conf file to load the module at boot. The output of lsmod is now:

But the problem persists.

I've updated the above post for clarity and to explain what I've since tried.
