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.

NVMe suspend fix targets the dGPU on MacBooks with discrete graphicsrevision 1 · captured 2026-09-28 21:23 UTC via poll

What happened

install/hardware/apple/fix-suspend-nvme.sh hardcodes the NVMe at PCI
0000:01:00.0:

NVME_DEVICE="/sys/bus/pci/devices/0000:01:00.0/d3cold_allowed"

if [[ -f $NVME_DEVICE ]]; then
  ...
  ExecStart=/bin/bash -c 'echo 0 > /sys/bus/pci/devices/0000\:01\:00.0/d3cold_allowed'

On MacBook models with discrete graphics that address is the dGPU, not the NVMe.
On a MacBookPro13,3:

$ lspci -s 01:00.0
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460/560D / Pro 450/455/460/555/555X/560/560X]
$ lspci -s 02:00.0
02:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM961/PM961/SM963

The guard [[ -f $NVME_DEVICE ]] passes because d3cold_allowed exists on any
PCI device, so the script reports success and enables the service. The result is
the opposite of what's intended on both counts:

$ cat /sys/bus/pci/devices/0000:01:00.0/d3cold_allowed   # Radeon Pro 460
0
$ cat /sys/bus/pci/devices/0000:02:00.0/d3cold_allowed   # NVMe
1

The discrete GPU is pinned out of D3cold — so it can't fully power down, costing
idle power and heat — while the NVMe the fix exists for is left untouched.

MacBookPro13,3 is matched explicitly by the script's own regex
(MacBookPro13,[123]), and it's the model in that list most likely to have a
dGPU shifting the PCI numbering.

What was expected

The service should target whichever PCI address the NVMe actually has.

Steps to reproduce

  1. Install Omarchy on a MacBook with discrete graphics (MacBookPro13,3 or 14,3).
  2. systemctl cat omarchy-nvme-suspend-fix.service → points at 0000:01:00.0.
  3. lspci -s 01:00.0 → the GPU, not the NVMe.

Fix

Derive the address instead of hardcoding it, e.g.:

NVME_PCI=$(basename "$(readlink -f /sys/class/nvme/nvme0/device)")

which gives 0000:02:00.0 here and 0000:01:00.0 on the models the current
code was written against. Machines that already ran the old script also need
d3cold_allowed restored to 1 on the GPU, since the wrong setting persists in
the enabled unit.

Happy to open a PR if you'd like.

### What happened

`install/hardware/apple/fix-suspend-nvme.sh` hardcodes the NVMe at PCI
`0000:01:00.0`:

```bash
NVME_DEVICE="/sys/bus/pci/devices/0000:01:00.0/d3cold_allowed"

if [[ -f $NVME_DEVICE ]]; then
  ...
  ExecStart=/bin/bash -c 'echo 0 > /sys/bus/pci/devices/0000\:01\:00.0/d3cold_allowed'
```

On MacBook models with discrete graphics that address is the dGPU, not the NVMe.

```
$ lspci -s 01:00.0
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460/560D / Pro 450/455/460/555/555X/560/560X]
$ lspci -s 02:00.0

1

`d3cold_allowed` restored to `1` on the GPU, since the wrong setting persists in
the enabled unit.
