I don't know why the firmware downgrade helps you; none of the GPU
firmware loads for your hardware. From you your log I gather your
machine has a 7800XT. Mapping that over to
https://docs.kernel.org/gpu/amdgpu/amd-hardware-list-info.html this is
GC 11.0.2 and DC 3.2.0.
None of those files changed.

None of that should change anything with your display.
Right now I suspect this is actually a compositor (mutter) bug and the
increased size of the initramfs is just changing the "timing" of when
gdm starts.
I'll add a mutter task for now until we can better understand what's
going on.

Title:
linux-firmware 20240318.git3b128b60-0ubuntu2.19 causes black screen on
login with dual 4K monitors at 200% scaling on Wayland (AMD GPU)
Status in linux-firmware package in Ubuntu:
Confirmed
Status in mutter package in Ubuntu:
New
Bug description:
Summary:
After automatic update from linux-firmware version .17 to .19 on October 17,
2025, Ubuntu 24.04 displays black screen on login when using dual LG ULTRAFINE
4K monitors with 200% fractional scaling on Wayland. The issue specifically
occurs when GNOME/GDM attempts to initialize displays at 200% scaling during
boot.
Hardware:
- CPU: AMD Ryzen 16-core
- GPU: AMD (integrated graphics)
- Monitors: 2x LG ULTRAFINE 4K (3840x2160) via DisplayPort
- Display Server: Wayland
- Desktop: GNOME
Steps to Reproduce:
1. Have dual 4K monitors configured at 200% fractional scaling
2. Update linux-firmware from .17 to .19
3. Save display configuration at 200% scaling
4. Reboot
5. Attempt to login
Expected Result:
Desktop should load normally with both monitors displaying correctly at 200%
scaling
Actual Result:
Black screen after login when monitors.xml contains 200% scaling configuration
Key Diagnostic Findings:
- Deleting ~/.config/monitors.xml allows login at 100% default scaling
- Changing to 200% scaling AFTER login works perfectly
- Problem only occurs when GDM/GNOME loads 200% scaling during boot
initialization
- Rebooting after setting 200% recreates the black screen issue
- This is a boot-time initialization bug, not a runtime scaling bug
Workaround:
Deleting ~/.config/monitors.xml before each login allows access, but requires
manual reconfiguration to 200% each session (unsustainable for daily use)
Fix:
Downgrading to linux-firmware=20240318.git3b128b60-0ubuntu2.17 resolves the
issue completely. All scaling levels work correctly with firmware .17.
Additional Information:
- Wayland is required for this hardware setup (X11 has display issues with
dual 4K monitors even on firmware .17)
- Single monitor configuration was not tested
- Issue appeared immediately after firmware update on Oct 17, 2025
- Firmware .17 works perfectly with Wayland + dual 4K + 200% scaling at all
times (boot and runtime)
- Bug is specific to boot-time display initialization with 200% fractional
scaling in firmware .19
System Information:
- Ubuntu Version: 24.04.3 LTS
- linux-firmware installed: 20240318.git3b128b60-0ubuntu2.17 (working -
currently held)
- linux-firmware candidate: 20240318.git3b128b60-0ubuntu2.19 (broken - causes
black screen)
