Bug ID: 202533
Summary: DVI Monitors blank in 4.20-6 kernel
Product: Drivers
Version: 2.5
Kernel Version: 4.20
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: acollier21@gmail.com
Regression: No
Running Fedora 29 with a Dell Precision M4700 and a Dell Pro2x dock. Has the
K1000 Nvidia card. Under the 4.19 kernel I was able to have all 3 of my
external monitors hooked up and working properly. Anytime I've tried booting
into any 4.20 kernel, only my VGA monitor will display, and the other two are
blank. Currently running the Nouveau drivers. I keep testing each 4.20 kernel
that comes out but none of them have fixed the issue.
Running on Gnome 3.30 under x11 if that matters.

--- Comment #1 from Ilia Mirkin (imirkin@alum.mit.edu) ---
There weren't a ton of changes to nouveau between 4.19 and 4.20. Can you do a
bisect?
There were some changes to add support for HDMI 2.0, but only on GM20x GPUs
(you have a GK10x GPU, which is earlier). And a handful of fixes to MST-related
object lifetime management. It's likely that you have a MST dock, but those
changes don't seem like they would cause anything that drastic.
Please include dmesg and xorg logs.

Doesn't seem like nouveau is loaded at all. Probably related to not being able
to get anything to come up on those screens...

You could try loading nouveau... or removing the configuration that is
preventing it from loading...

Thanks for your patience. Figured out the error. For whatever reason, there was
a blacklist file in /etc/modprobe.d/ that was blacklisting the nouveau drivers.
4.20 recognized the blacklist while 4.19 did not.
Thanks for your direction!
