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
Created attachment 142526 --> https://bugs.freedesktop.org/attachment.cgi?id=142526&action=edit 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.
