Description David W. Legg 2024-02-23 14:22:42 UTC

Description of problem:
After upgrading from 6.6.14-200.fc39.x86_64 kernel to 6.7.3, my HDMI display stopped working on boot, using only my VGA display instead of both.

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-1.0.17-6.fc39.x86_64 works. Higher versions do not.

How reproducible:
100%

Steps to Reproduce:
1. Upgrade to 6.7 kernel.
2. Reboot.
3.

Actual results:
Only one display working.

Expected results:
Both displays working.

Additional info:
When boot starts, it uses the HDMI display, but then it switches to the VGA one and no longer uses the HDMI display. I never see both working simultaneously.
