## What happened

After resuming from suspend (s2idle), the external monitor connected through a
USB-C dock never comes back. The DRM connector stays `disconnected` and no
amount of software intervention restores it — **only a full reboot works.**
Unplugging and replugging the dock's USB-C cable does *not* restore it.

The dock's USB side recovers fine on resume (hub, audio interface, mic all
re-enumerate). Only the DisplayPort alt-mode path is dead.

Everything was working on 4.0.2

## What I expected

The external monitor re-attaches on resume, as it does after a fresh boot.

## Steps to reproduce

1. Boot with a USB-C dock attached, external monitor works (DP-3, 1920x1200@60).
2. Suspend the laptop (lid close / idle).
3. Resume.
4. External monitor stays black. `hyprctl monitors all` lists only `eDP-1`.
5. Replugging the dock does nothing. Reboot is the only fix.

## Diagnostics

Kernel log immediately after resume — the Type-C connector interface fails:

```
ucsi_acpi USBC000:00: unknown error 0
ucsi_acpi USBC000:00: GET_CABLE_PROPERTY failed (-5)
```

DisplayPort alt mode never re-enters:

```
/sys/class/typec/port0-partner/number_of_alternate_modes = 2
  port0-partner.0  svid=8087 (Thunderbolt3)  active=no
  port0-partner.1  svid=ff01 (DisplayPort)   active=no
/sys/class/typec/port0-partner/supports_usb_power_delivery = no
/sys/class/typec/port0-partner/usb_power_delivery_revision = 0.0
```

(`port0` itself still reports `power_operation_mode=usb_power_delivery`,
`usb_power_delivery_revision=3.0`, so the partner-side PD state is what's lost.)

Hyprland/aquamarine sees the connector drop and never get it back:

```
drm: Connector DP-3 disconnected
ERR drm: Cannot commit a disconnected output
drm: DP-3 is not connected, clearing stale crtc 269
```

All DP connectors report disconnected while the dock is physically attached:

```
/sys/class/drm/card1-DP-1/status: disconnected
/sys/class/drm/card1-DP-2/status: disconnected
/sys/class/drm/card1-DP-3/status: disconnected
/sys/class/drm/card1-DP-4/status: disconnected
/sys/class/drm/card1-eDP-1/status: connected
```

## What I tried (none of it works)

- Unbind/rebind `ucsi_acpi` (`USBC000:00`) via
  `/sys/bus/platform/drivers/ucsi_acpi/{unbind,bind}` — rebinds successfully but
  `GET_CABLE_PROPERTY failed (-5)` returns immediately and alt modes stay inactive.
- Forcing a connector re-probe: `echo detect > /sys/class/drm/card1-DP-*/status`.
- Physically unplugging and replugging the dock's USB-C cable.

Only a full reboot (which power-cycles the PD controller) recovers DP output.

## System details

- Omarchy: 4.0.3-1
- Kernel: Linux 7.2.3-arch1-3
- CPU/GPU: Intel Meteor Lake-P, Intel Arc Graphics `[8086:7d55]`, `i915` driver
- Hyprland: 0.56.2 (commit efb5099)
- Sleep mode: `s2idle` (only mode available on this platform)
- Internal display: eDP-1, 2256x1504@60
- External display: 1920x1200@60 via DP-3 over a USB-C dock (DP alt mode;
  Genesys Logic hub, not a Thunderbolt-tunnelled dock)

This looks like an upstream kernel / platform-firmware issue in the
`ucsi_acpi` Type-C path on Meteor Lake rather than something Omarchy controls,
but flagging it here in case others on Omarchy hit the same thing.
