Red Hat Bugzilla – Bug 1475730
Monitors enter powersave mode during boot
Last modified: 2017-10-17 16:07:15 EDT
Description of problem:
I have a dual-monitor setup with an older Radeon HD 5870 (Sapphire Technology Device e140) and a Ryzen 1700 CPU.
During boot both monitors enter powersave mode and stay like that.
Adding 'nomodeset' gets me past that and I can log in (graphics mode).
But then only one monitor can be configured, both monitors display the same.
When I boot kernel-4.11.8-200.fc25.x86_64 with the same F26 environment, no 'nomodeset' is required and both monitors are detected and can be used.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot kernel-4.11.11-300.fc26.x86_64
