### System details
- **Device:** ASUS ROG Zephyrus G14 (2024 / GA403 series) *(Also reported on MSI Stealth A16 AI+ in #8030)*
- **CPU / iGPU:** AMD Ryzen AI 9 HX 370 (Radeon 890M / RDNA 3.5 architecture)
- **dGPU:** NVIDIA GeForce RTX 40-Series
- **Display:** Internal 14" 2.8K OLED 120Hz (`eDP-1`, 2880x1800)
- **OS / Compositor:** Omarchy 4.x (`quattro`), Hyprland 0.56.2 (Aquamarine 0.14+), `uwsm` session manager

### What's wrong?

#### 1. Symptom
On a fresh install of Omarchy on AMD Strix Point laptops (specifically tested on ASUS ROG Zephyrus G14 GA403 with Ryzen AI 9 HX 370 / Radeon 890M), the system hangs on a black screen immediately after login/display manager.

Switching to a TTY and inspecting Hyprland startup logs shows the compositor stalling at:
```
Creating the AquamarineRenderer!
[AQ] atomic drm request: failed to commit: Cannot allocate memory
```
*(This is the same silent boot freeze reported by users on Strix Point hardware in #8030).*

#### 2. Root Cause
Hyprland's Aquamarine backend encounters an atomic DRM commit failure when initializing the DRM plane on AMD Strix Point (Radeon 890M / RDNA 3.5) iGPUs. To initialize successfully, Aquamarine must fall back to legacy DRM commits and software cursors:
- `AQ_NO_ATOMIC=1`
- `WLR_NO_HARDWARE_CURSORS=1` (and `no_hardware_cursors = true` in looknfeel)

#### 3. Critical Timing Nuance
Aquamarine reads `AQ_NO_ATOMIC` directly from the process environment **before** reading Hyprland Lua configuration files. Setting this inside `~/.config/hypr/hyprland.lua` via `hl.env()` is evaluated too late. It must be exported in the session environment:
- `~/.config/uwsm/env-hyprland`
- `~/.config/uwsm/env`
- `/etc/environment`

#### 4. Additional Hardware Fixes Tested for GA403 / Strix Point
1. **Early KMS in Initramfs:** `mkinitcpio.conf` needs early module loading (`MODULES=(amdgpu nvidia nvidia_modeset nvidia_uvm nvidia_drm)`), and the bootloader requires `nvidia_drm.modeset=1 nvidia_drm.fbdev=1`.
2. **Persistent Colon-Free Udev Symlinks:** As noted in #8776, Aquamarine splits `AQ_DRM_DEVICES` on `:`, breaking standard `/dev/dri/by-path/pci-...` paths. A persistent udev rule mapping the iGPU to `/dev/dri/amd-igpu` allows clean multi-GPU routing.
3. **Internal OLED Scaling:** Proper default scaling in `~/.config/hypr/monitors.lua`:
```lua
local omarchy_monitor_scale = 1.5
local omarchy_gdk_scale = 1.5

hl.env("GDK_SCALE", tostring(omarchy_gdk_scale))

hl.monitor({
    output = "eDP-1",
    mode = "2880x1800@120",
    position = "0x0",
    scale = omarchy_monitor_scale
})
```

#### 5. Tested Setup Script
A standalone script that detects Strix Point / NVIDIA hardware, configures early KMS, writes the udev symlinks, sets up `uwsm` environment flags, and formats `monitors.lua` has been tested and confirmed working:
