kernel log messages of the affected 4.17.6 kernel

Description of problem:
Booting 4.17.6-200.fc28 gives a lot of flickering, some nouveau related error messages and while it knows about the display attached to the display port of the dock, there's no output there. The previous 4.17.5-200 kernel works fine in that regard (it "forgets" about the external display when undocked but that's an old, different problem).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot

Actual results:
- boot takes longer
- flickers back and forth a few times between text and graphical modes before displaying the login screen
- only the internal display shows content, the external monitor stays dark even though it is recognized, e.g. in GNOME settings
- much more nouveau related error messages than the 4.17.5 kernel

Expected results:
- external monitor displays content
- no excessive flickering, error messages

Thanks for the report. We track the graphics kernel bugs on the driver component, so I've reassigned it.

Comment 3 Nils Philippsen 2018-07-23 09:06:40 UTC
Things are working for me again with these releases of the kernel and xorg-x11-drv-nouveau:


I'll close the bug now. Thanks!
