Hi all,
Using
Fedora Linux 38.20230421.0 (Silverblue)
AMD Ryzen™ 7 PRO 4750G with Radeon™ Graphics × 16
The second monitor is always a black screen, listed as “unknown display 640x480”. This persists on wayland and Xorg.
Prior to f38, the it happened only after a suspend, and a hard reboot solved the problem, but now on 38 that doesn’t work either.
When I turn on the second moitor and scans the sources, I see this in systemctl -r -k
, so thats three scan loops.

Apr 24 12:09:39 fedora kernel: [drm:detect_link_and_local_sink [amdgpu]] *ERROR* No EDID read.
I have no idea on how to approach this, it’s way above my skill level, so if anyone have a fix, pls chime in.
Cheers!
(EDIT: I removed the debug-info that was here)
