## What happens

The lock screen powers the display off 5 seconds after it appears (and 5 seconds after each key press). The delay is hard-coded and has no setting.

Behind a KVM switcher this breaks the machine:

1. Switch the KVM to the Omarchy machine. HDMI comes up and the lock screen shows.
2. 5 seconds later the lock screen runs `omarchy-brightness-display off`, which disables DPMS.
3. The KVM sees no video signal, scans to its other input, and disconnects its USB hub from this machine.
4. The monitor shows the lock screen for about a second, then "searching for source". The keyboard and mouse behind the KVM never become usable.

If the KVM cuts USB while a full-speed keyboard or mouse behind its hub is still enumerating, the xHCI controller can get stuck. From then on, every full-speed device behind any hub fails with `device descriptor read/64, error -110` and `xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command`, across KVM power cycles and port changes. Only unbinding and rebinding `xhci_hcd` (or a reboot) recovers it. That part is a kernel/xHCI weakness, but the 5-second blank is what triggers it on every switch.

## Where

`shell/plugins/lock/Service.qml`:

```qml
Timer {
  id: idleBlankTimer
  interval: 5000
  ...
  onTriggered: { ... if (root.lockRequested && !root.authenticatingPassword) root.runBlank() }
}
```

`runBlank()` runs `omarchy-brightness-keyboard off; omarchy-brightness-display off`, and the `off` branch of `omarchy-brightness-display` dispatches `hl.dsp.dpms({ action = "disable" })`.

`idle.screensaver` and `idle.lock` in `shell.json` do not affect this timer.

## Expected

A way to change or disable the lock-screen blank, for example an `idle.blank` (or `lock.blankSeconds`) key in `shell.json`, where `0` or `false` keeps the display on while locked. Whether the display powers off while locked should be a setting.

## Workaround in use

A user script started from `~/.config/hypr/autostart.lua` listens on `.socket2.sock` for `monitoradded` and re-enables DPMS once a second for 60 seconds after each hotplug. That keeps the KVM on the machine long enough to enumerate USB and unlock.

## System

- Omarchy 4.0.4-1
- Intel Haswell iGPU (i915, `8086:0412`), single HDMI output
- KVM with a Genesys Logic USB 2.1 hub (`05e3:0610`)
