### System details

Omarchy 4.0.0-1, i5-12600K, RTX 5070,Keyboard layout: fr 

### What's wrong?

## Describe the issue

The SDDM greeter always uses the US/QWERTY layout, regardless of the system keyboard layout. On a FR/AZERTY system, the login password field is QWERTY, so any password containing layout-sensitive characters cannot be typed. There is no layout indicator or switcher on the greeter.

Note: the system XKB configuration is already correct, so `localectl set-x11-keymap` is not the fix. Hyprland ignores `/etc/X11/xorg.conf.d/00-keyboard.conf` entirely — it only honours `input { kb_layout }` in its own config — which is why the greeter is wrong while the rest of the system is right:

```
$ localectl status
  VC Keymap: fr
  X11 Layout: fr
  X11 Model: pc105

$ cat /etc/X11/xorg.conf.d/00-keyboard.conf
  Option "XkbLayout" "fr"
  Option "XkbModel" "pc105"

$ hyprctl getoption input:kb_layout
  str: fr
```

Cause: the greeter runs inside its own Hyprland instance.

```ini
# /etc/sddm.conf.d/10-wayland.conf
[Wayland]
CompositorCommand=start-hyprland -- --config /usr/share/sddm/hyprland.conf
```

Neither `/usr/share/sddm/hyprland.conf` nor the newer `/usr/share/sddm/hyprland.lua` declares an input block — both only set `misc{}` and `animations{}`. With no `kb_layout`, Hyprland falls back to its built-in default, `us`.

Confirmed: pointing `CompositorCommand` at a config that sources the shipped one and adds `input { kb_layout = fr }` makes the greeter AZERTY. The fix therefore belongs in the greeter's compositor config.

## Steps to recreate

1. Install with a non-US layout (FR here) and full-disk encryption.
2. Disable autologin by moving `/etc/sddm.conf.d/autologin.conf` out of the directory. SDDM reads every file in `conf.d` regardless of extension, so renaming it to `.disabled` in place is not enough — it is still parsed.
3. Reboot.
4. The LUKS decryption prompt is correctly AZERTY (vconsole `KEYMAP=fr`).
5. Seconds later, on the same physical keyboard, the SDDM greeter is US/QWERTY.

Both prompts appear during a single boot, so this is not a logout or session-restart problem: the greeter is always US. With autologin enabled (the default) the greeter is skipped at boot and only appears after a logout, which is why the issue is easy to miss.

## Expected

The greeter's Hyprland config should carry the system keyboard layout (`kb_layout`, `kb_variant`, `kb_options`), so the greeter matches both the LUKS prompt and the user session.

## Workaround

Verified working — the greeter is AZERTY after a logout with this in place. The layout is hardcoded here; a proper fix would detect the system layout, as is already done for `~/.config/hypr/input.conf`.

```
# /etc/sddm/hyprland-kbd.conf
source = /usr/share/sddm/hyprland.conf

input {
    kb_layout = fr
    kb_model = pc105
}
```

```ini
# /etc/sddm.conf.d/99-keyboard.conf
[Wayland]
CompositorCommand=start-hyprland -- --config /etc/sddm/hyprland-kbd.conf
```

## Side notes from the 4.0.0 update path

Updated 3.8.2 to 4.0.0 with `omarchy update`, not a fresh ISO install. Neither of these causes the layout bug, but both surfaced while investigating.

- 4.0.0 ships `/usr/share/sddm/hyprland.lua` and a `10-wayland.conf.pacnew` pointing at it, while the active `10-wayland.conf` still points at `hyprland.conf`. Since SDDM's `conf.d` reader does not filter on the `.conf` extension, the `.pacnew` is parsed alongside the real file and both set `CompositorCommand` with different values.
- `/usr/share/sddm/hyprland.conf` is not owned by any package (`pacman -Qo` returns "No package owns"), so it lingers after the update.

## Related

#5754 — same class of problem on hyprlock after the 3.8.0 update: auth surfaces do not inherit the system keyboard layout.

#6878 — Quattro upgrade drops non-US layout in the Hyprland *session* when vconsole.conf has only KEYMAP (falls back to `us` via `vconsole.XKBLAYOUT or "us"`). Different component and different cause: my session is correct and my vconsole.conf does contain XKBLAYOUT=fr. The greeter's compositor config doesn't read vconsole at all — it simply has no input block.
