Bug ID: 108806
Summary: AMDGPU Failed to read EDID from display
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: michael.lindman@gmail.com

boot log showing EDID failure
When connecting one of my monitors to the system it defaults to 1024x768 and
not the native resolution and grepping through the kernel logs shows that
AMDGPU fails to read the EDID of the display.
[ 5.054779] [drm:dc_link_detect [amdgpu]] *ERROR* No EDID read.
The display was working fine as of kernel 4.18.18 with the issues arising upon
4.19.2.
I am using a POLARIS 10 GPU and both displays are connected to DisplayPort with
the Asus PG2780 having the issues with failing to grab the EDID.
DisplayPort-0 LG 25UM65-P
DisplayPort-1 ASUS PG278Q

Same problem here with RX480 and ASUS PG278Q.
Can't figure out what's broken.
Is it the bios of the card, the EDID of the monitor or the code in the amdgpu
module ?

--- Comment #2 from Cameron <cam@neo-zeon.de> ---
I'm also having having the "No EDID read." issue with this monitor and a wx
5100. With the generic Ubuntu 5.0.0-20 kernel on 10.94 as well as on my custom
5.1.17 kernel.
However, I don't even get anything on the screen. My monitor just flashes from
black to lighter black... However, I'm running on POWER (PPC) so I may be
encountering additional issues in my case.
However, the petitboot firmware gives me a text screen. The firmware is running
4.19.0 which suggests that something has broken since then as others have
suggested.
