Dual Monitor Black Screen: Wayland, and Radeon

Hello anyone :smile:

I’ve been pouring through posts here on the forum and elsewhere, but can’t land on a solution.

My second monitor usually works but lately not at all. It is connected, does have a signal, I can see backlight, can move mouse curser and drag windows to the second screen, but is black screen. I have booted with and without the HDMI connected, have tried lts kernel both ways, and various attempts from previous posts but I got nothing!

Autorandr shows me Detected Wayland session 'Wayland-0' Exiting

Most recent;y I took a stab at wdisplays but it shows the error Compositor doesn't support wlr-output-management-unstable-v1.

I’m not sure where to go from here and appreciate any help!

Thanks for that reminder :laughing:


Have you checked for a new UEFI Bios update. Not sure what the exact model this laptop is but it looks like there is an update for 2023 if i have it right. It might not hurt to update it if there is a new Bios update. Not sure it will fix this issue but is important for Ryzen processors.

Edit: Is it the Delta 15 A5EFK

Edit: Check if this is correct.

Edit: I see your current version is E15CKAMS.105 date: 10/28/2021

All correct, its the Delta 15 A5EFK-001 and I was able to update the Bios. Strange thing though is before I did that, the second monitor worked all of a sudden! I flashed the bios anyway, waiting to see what happens when I move the laptop away from my desk and back again to the second screen.

Thought we had it sorted out but my luck ran out :rofl:

Updated the bios and things were just fine, now it’s back to the behavior of post 1. Worked well for about 4 days though, but also noticed when I plug in the HDMI the dash to dock starts jumping up and down. Weird.

Does your monitor only have HDMI or does it also have DP?

It does have DP. Oddly enough it’s working again. Another clue lol… it’s a very inconsistent problem it seems.
