OpenSUSE: NetworkManager D-Bus timeout crashes Noctalia (Wayland disconnect / Broken pipe)

[tofan79]

Environment

• Noctalia: v5.0.0
• OS: openSUSE Tumbleweed
• Compositor: Mango WM (Wayland)
• GPU: AMD Radeon Vega (integrated) + NVIDIA RTX 3050 Mobile

Steps to reproduce

1. Open the network widget in Noctalia
2. Select a WiFi network and attempt to connect
3. If the connection fails or times out (wrong password, unreachable network, etc.)

Expected behavior

Connection attempt should fail gracefully with an error notification.

Actual behavior

Noctalia crashes with a Wayland disconnect:

Root cause

The NetworkManager D-Bus call (AddAndActivateConnection) blocks the Wayland event loop for ~25 seconds on timeout, causing the Wayland display connection to break. The compositor disconnects Noctalia because it cannot process events during this time.

Well for me it just keeps spinning endlessly.
At some point it will stop doing that but it gives no error or alike.

On which version are you exactly (commit date +sha)?

[tofan79]

I am using the version Commit 2ebca92
Or
Noctalia V5

Hi, afaik this issue is because of polkit prompt specifically on openSUSE, you could potentially fix it by adding these into ur /etc/polkit-1/rules.d/49-networkmanager.rules. Also make sure ur user is in the wheel group

polkit.addRule(function(action, subject) { 
	var allowed_actions = [
		"org.freedesktop.NetworkManager.enable-disable-network",
		"org.freedesktop.NetworkManager.enable-disable-wifi",
		"org.freedesktop.NetworkManager.enable-disable-wimax",
		"org.freedesktop.NetworkManager.enable-disable-wwan",
		"org.freedesktop.NetworkManager.network-control",
		"org.freedesktop.NetworkManager.settings.modify.own",
		"org.freedesktop.NetworkManager.settings.modify.system",
		"org.freedesktop.NetworkManager.wifi.scan",
		"org.freedesktop.NetworkManager.wifi.share.open",
		"org.freedesktop.NetworkManager.wifi.share.protected"
	]
	if (allowed_actions.indexOf(action.id) >= 0) {
		if (subject.isInGroup("wheel")) {
			return polkit.Result.YES;
		}
	}
})
