[solved] Cinnamon + NetworkManager broken (dhcpcd disco loop)

Hi there,

since the last NM update it does not seem to work with Cinnamon anymore. The connections keep connecting/disconnecting in a loop after login, I can only break the loop if I disable and re-enable the connection. At least that works for LAN, Wifi still loops.

It also happens on my desktop PC (LAN only) when I disconnect the LAN in NM (loop starts after disco), so I guess I am not the only one having those issues?
WiFi is an Intel 3945 btw, but I don't think that it's a driver issue.

I'm trying to narrow it down if this is a cinnamon issue, can any gnome users confirm that NM 1.0 is working properly without issues (WiFi)?

Cheers,
acidicX

I remember booting up Cinnamon just after upgrading NetworkManager to version 1.0.0 and it was working perfectly fine here. Works fine on MATE GTK3 as well.

I'm using gnome 3.14 and I think I have the same problem. Downgraded to networkmanager-0.9.10.0-4 and it seems to have gone away so I guess it's the same problem.

I'm just using ethernet and it would connect and disconnect multiple times a second for about 10 seconds after gdm started.

Re: [solved] Cinnamon + NetworkManager broken (dhcpcd disco loop)

@somniac: thx. Yes, seems to be the dhcpcd backend in NM is broken.
I now disabled dhcpcd - so at least the network works again.
Bug upstream: https://bugzilla.gnome.org/show_bug.cgi?id=743700
IPv6 support is gone though. I tried using the new, internal NM dhcp client and dhclient, both won't provide an IPv6 binding.
Is there a way to get IPv6 support back?

Rant: NM is (usability-wise) still the best GUI, but sometimes it really looks like a heap of ... under the hood... :-(
