Omarchy

ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

MacBookAir5,1: minimum brightness turns backlight fully off and Fn+F2 cannot recoverrevision 1 · captured 2026-09-28 21:23 UTC via poll

System

  • MacBook model: MacBookAir5,1
  • Omarchy: 4.0.4-1
  • Kernel: 7.2.5-3-omarchy
  • GPU: Intel Ivy Bridge mobile GT2 / HD Graphics 4000
  • Display: eDP-1, Apple Color LCD, 1366x768
  • Backlight device: acpi_video0
  • Backlight range: 1/15

Steps to reproduce

  1. Boot into Omarchy on the MacBook Air.
  2. Press Fn+F1 repeatedly until brightness reaches its minimum.
  3. The display becomes completely black.
  4. Press Fn+F2 repeatedly.

Expected behavior

The minimum brightness should leave the backlight at a nonzero hardware level, and Fn+F2 should restore brightness.

Actual behavior

The display becomes completely black. Pressing Fn+F2 does not restore it, so the computer cannot be used normally.

The display can be recovered from a TTY or SSH session with:

brightnessctl -d acpi_video0 set 50%

Additional details

The MacBook exposes only 15 discrete backlight levels. Omarchy appears to use a minimum of 1%, which may round down to hardware level 0. The likely affected path is the omarchy-brightness-display handling for low-resolution ACPI backlight devices.

The issue was reproduced with the stock Omarchy brightness keybindings; no local Hyprland brightness override is configured.

Diagnostics

omarchy-debug --no-sudo --print was run locally. Relevant results:

## Steps to reproduce

1. Boot into Omarchy on the MacBook Air.
2. Press `Fn+F1` repeatedly until brightness reaches its minimum.
3. The display becomes completely black.
4. Press `Fn+F2` repeatedly.

## Expected behavior

The minimum brightness should leave the backlight at a nonzero hardware level, and `Fn+F2` should restore brightness.

## Actual behavior

The display becomes completely black. Pressing `Fn+F2` does not restore it, so the computer cannot be used normally.

The display can be recovered from a TTY or SSH session with:

```sh
brightnessctl -d acpi_video0 set 50%
```

## Additional details

The MacBook exposes only 15 discrete backlight levels. Omarchy appears to use a minimum of `1%`, which may round down to hardware level `0`. The likely affected path is the `omarchy-brightness-display` handling for low-resolution ACPI backlight devices.

The issue was reproduced with the stock Omarchy brightness keybindings; no local Hyprland brightness override is configured.

## Diagnostics

`omarchy-debug --no-sudo --print` was run locally. Relevant results:
