Automatic modesetting fails when attaching monitors with some AMD hardware
With some configurations, adding an additional monitor to a system using AMD hardware can fail to activate the new hardware automatically.
The problem is currently under investigation.
To workaround the issue, system administrators should manually call xrandr(1) to enable the monitor.

scratch build
Alex, would it be possible for you to test this scratch build? It's for rhel 7.4 so you need to install the beta plus this rpm.
Hello, This will not be able to make RHEL 7.4. This is now requested for RHEL 7.5. Thank You Joe Kachuck *** Bug 1366169 has been marked as a duplicate of this bug. *** Waiting on test feedback from customer, so clearing need-info flag. Hello Alex, Please confirm if you are still seeing this issue on RHEL 7.4? Thank You Joe Kachuck (In reply to Joseph Kachuck from comment #21) > Hello Alex, > Please confirm if you are still seeing this issue on RHEL 7.4? > > Thank You > Joe Kachuck Note that there is a test build in comment 16 I can confirm hotplug is working properly on 7.3. Haven't had a chance to test 7.4 yet. Hello, From the last update. I am closing this BZ as current release. Please reopen if required. Thank You Joe Kachuck |
