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

Surface Book 2 touchscreen dead on stock kernel (needs linux-surface/IPTS)revision 1 · captured 2026-09-28 21:24 UTC via poll

Summary

On Microsoft Surface Book 2, the touchscreen works under Windows but not under Omarchy (or stock Arch/Ubuntu kernels). Keyboard and touchpad are fine.

Cause

Book 2 (and other IPTS-era Surfaces) use Intel Precise Touch & Stylus. Upstream/linux has no IPTS driver, so no touchscreen input node appears. Omarchy’s install/hardware/surface.sh only installs linux-firmware-marvell — not enough for touch.

Confirmed on Omarchy 4.0.x (linux 7.1.9-arch1-2):
- PCI: Intel iTouch Controller 8086:9d3e
- No ipts module, no IPTS/IPTSD devices in /proc/bus/input/devices

Fix (verified)

Install linux-surface kernel + userspace + firmware, boot that kernel:

# key + [linux-surface] repo per https://pkg.surfacelinux.com/arch/
pacman -S linux-surface linux-surface-headers iptsd surface-ipts-firmware
# Limine: prefer linux-surface (keep stock linux as fallback)
# reboot → uname -r should contain "surface"

After reboot on this machine:
- ipts loaded, iptsd@….service running
- Touchscreen + stylus virtual devices present; touch works

Ready PR

#7857 already implements the installer path (repo key, packages, Limine drop-in, tests). Please see the Surface Book 2 verification comment there for two extras that mattered on this hardware:

  1. Install surface-ipts-firmware as well
  2. Prefer linux-surface as default boot so touch works without a manual menu pick

## Summary

On **Microsoft Surface Book 2**, the touchscreen works under Windows but not under Omarchy (or stock Arch/Ubuntu kernels). Keyboard and touchpad are fine.

## Cause

Book 2 (and other IPTS-era Surfaces) use Intel Precise Touch & Stylus. Upstream/`linux` has **no IPTS driver**, so no touchscreen input node appears. Omarchy’s `install/hardware/surface.sh` only installs `linux-firmware-marvell` — not enough for touch.

Confirmed on Omarchy 4.0.x (`linux 7.1.9-arch1-2`):
- PCI: Intel iTouch Controller `8086:9d3e`
- No `ipts` module, no IPTS/`IPTSD` devices in `/proc/bus/input/devices`

## Fix (verified)

Install [linux-surface](https://github.com/linux-surface/linux-surface) kernel + userspace + firmware, boot that kernel:

```bash
# key + [linux-surface] repo per https://pkg.surfacelinux.com/arch/
pacman -S linux-surface linux-surface-headers iptsd surface-ipts-firmware
# Limine: prefer linux-surface (keep stock linux as fallback)
# reboot → uname -r should contain "surface"
```

After reboot on this machine:
- `ipts` loaded, `iptsd@….service` running
- Touchscreen + stylus virtual devices present; touch works
