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.

🐞 Wired Internet Slow / DNS Hijacking After Install

Issue:
Fresh Omarchy Linux install → wired internet works but is slow/unreliable.
ping google.com sometimes resolves to weird IPs (e.g. 192.178.x.x), not real Google addresses.

Cause:
Default systemd-networkd config accepts ISP DNS via DHCP, which can be slow or hijack requests.

Fix:
Edit /etc/systemd/network/20-ethernet.network:

[Match]
Name=en*

[Network]
DHCP=yes
DNS=1.1.1.1
DNS=8.8.8.8
Domains=~.

[DHCP]
UseDNS=false

Then:

sudo systemctl restart systemd-networkd systemd-resolved

✅ After this, DNS is fast, secure, and resolves correctly.

Suggestion:
Set UseDNS=false by default in the live ISO’s network config to avoid this post-install pitfall.

### 🐞 Wired Internet Slow / DNS Hijacking After Install

**Issue**:  
Fresh Omarchy Linux install → wired internet works but is **slow/unreliable**.  
`ping google.com` sometimes resolves to weird IPs (e.g. `192.178.x.x`), not real Google addresses.

**Cause**:  
Default `systemd-networkd` config accepts **ISP DNS via DHCP**, which can be slow or hijack requests.

**Fix**:  
Edit `/etc/systemd/network/20-ethernet.network`:
```ini
[Match]
Name=en*

[Network]
DHCP=yes
DNS=1.1.1.1
DNS=8.8.8.8
Domains=~.

[DHCP]
UseDNS=false
```
Then:
```bash
sudo systemctl restart systemd-networkd systemd-resolved
```

✅ After this, DNS is fast, secure, and resolves correctly.

**Suggestion**:  
Set `UseDNS=false` by default in the live ISO’s network config to avoid this post-install pitfall.
