Hi,
I had an old computer that run with no 3D processor and an RTX 3070 all was fini on KDE + Wayland + Dual Monitor.
My new PC is:
Operating System: Arch Linux
KDE Plasma Version: 6.4.3
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Kernel Version: 6.15.9-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7800X3D 8-Core Processor
Memory: 32 GiB of RAM (30.5 GiB usable)
Graphics Processor 1: AMD Radeon RX 9070 XT
Graphics Processor 2: AMD Radeon Graphics
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: B850M GAMING X WIFI6E
System Version: Default string-CF-WCP-ADO
PSU: 800W
Monitor cable: Was working fine with the RTX3070, official DP provided by GIGABYTE
Color Profile: 10 bits (Auto)
Refresh Rate: 164.80hz
Resolution: 2560x1440
DM: Wayland
Vulkan Driver Version: Mesa 25.1.7-arch1.1
When my PC is turned on, at a random time one of my screen is reconnecting like we unplugged the cable then reconnect the cable (DP). Sometimes its the left one, someitmes its the right one
I try with `amdgpu.runpm=0` but it doesnt make a difference. I disabled 3D Boost in Bios and XMP Profile and it still happening.
I'm running under the latest firmware, latest `mesa`, latest `linux-fimrware-amdgpu`, latest `vulkan-radeon`
No error in dmesg
No error in journalctl (only wireless issue because of WIFI 7)
No Disconnect without automatic Reconnect
No Desktop resize so both monitor are always detected it just turn off/on the screen but when it turn off my Windows doesnt switch to another screen
No more problem when im running OCCT it is just at random times
No MODULES added in mkinitcpio.conf
dmesg | grep amdgpu:

- I'm not a kernel developer but I'm running linux since 8 years so I know what I'm doing when opening a terminal
- It did me that issue after a fresh install made with archinstall (5th PC on arch so thx to this script to make the process more faster)
- It look like some kernel parameters causing error and i cant boot correctly to my desktop : adding amdgpu.dpm=0 causing this errors
- Also I have added some options for to disable power management in /etc/modprobe.conf.d/40-amdgpu.conf (I'm sorry i didnt have the options anymore). removing them doesnt make the system boot, it is only when i removed amdgpu.dpm=0 I can boot again correctly
- I set loglevel=7 amdgpu.dmesg_log=1 drm.debug=0x1e to enable lot of logs and Im waiting for another screen disconnect
- I suspect that my screens have DP 1.2 and the GPU have 2.1a so may be I will need to add amdgpu.dc=0 to disable the Display Core feature
In the journal sometimes i have :

To have both dGPU and iGPU running at high rate every times and no hardware brightness management through the software
It look like there are multiple peoples that have driver issues with Modern AMD GPU : https://gitlab.freedesktop.org/drm/amd/-/issues/

Hi,
I've been having a very similar problem for a few weeks on a HP EliteBook 845 14 inch G10 Laptop. It does not happen to any external screens connected through HDMI or USB-C, only on the internal one, eDP-1.
After I suspend, there's a good chance that the screen stays black when it awakes. If I suspend enough times I can almost always get it back on. Once it's working, it never goes black by itself, no errors show up, even if I close the lid (I deactivated suspend on lidclose to avoid the suspend problem). It will only fail if I suspend or if I turn it on and off with wlr-randr or xrandr. The screen failure seems quite random but when it does fail, it can take 20 or more attempts to get back on.
Here are the errors after each failed attempt to get the screen to turn on:

I don't have seem to have an EDID problem.
amdgpu 0000:c3:00.0: amdgpu: [drm] Using ACPI provided EDID for eDP-1BTW, the problem occurs in both X and Wayland and on multiple kernels, including LTS and Zen. I haven't tested on windows or other operating systems. I read of some people having these erreurs due to faulty cables or a GPU that's not properly seated. I opened the laptop but couldn't find any bad connections. My best guess is that it's a hardware issue.

Hi,
Happy to see someone with the same problem! IMO it's more a driver issue than an hardware one may be the driver does not support DP 1.X on a DP 2 GC. I submitted an issue on the gitlab and I'm waiting for an answer. Yeah sometimes it will not have problem for 2-3 hours and sometimes it will reboot the screen like 3 or 4 times in 10 minutes
