Status changed to 'Confirmed' because the bug affects multiple users.

I just tried running this command again now that 12.10 is out of beta, and the same issue occurs.

Same thing here.
"restart networking" crashes unity

Hello,

Same problem with Ubuntu server 12.04.1 + gnome-core and Ubuntu desktop 12.04.1

The crash happens with "gnome shell" ou Unity

It depends on the machine but all the desktop environnement can disapear.

Hi,
Same issue for me on two machines running 12.10.

The only workaround I have found is to restart Unity whenever this happens
(Access a shell with ctrl+alt+1, login, then just type 'unity')

Confirming the bug. /etc/init.d/networking stop crashes unity with all the updates. Currently :
NAME="Ubuntu"
VERSION="12.04.1 LTS, Precise Pangolin"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu precise (12.04.1 LTS)"
VERSION_ID="12.04"

Confirming the bug. /etc/init.d/networking stop crashes unity with all the updates. Currently :
NAME="Ubuntu"
VERSION="12.10"

This happens to me also. I only notice it when installing a new system, since I don't use Unity otherwise. I just saw it in 13.04:

I don't use network-manager, in fact I've uninstalled it.
I've configured static networks for 3 ethernet cards in /etc/network/interfaces
Running "sudo restart networking" now causes the problem. It doesn't kill the Unity session, but terminates all the running programs and makes it unusable.
All I can do after that is switch to a terminal with ctr-alt-F1 and reboot.

this happen to me using ubuntu 13.04. when set network manually and restart network unity will crash.

Same here...

Can someone tell me how can i recover from this without rebooting the system ?

I've noticed that the same thing happens when using Xubuntu (XFCE), which suggests that it's nothing to do with Unity but has something to do with the underlying layers in the window system. Since X is a networked window system, you may expect something like this to happen, but I don't remember seeing it until the last couple of years.

Once in the console I can use kill -9 to terminate X, but the graphical session manager doesn't restart automatically. In Xubuntu I'd guess that you need to restart lightdm if you want to avoid rebooting.

I suspect that restarting the networking is also resetting the loopback device and breaking the connections between X clients and the window server. Perhaps the network restart script changed at some point.

Hi, I assumed this is the duplicate issue as bug 1072518, while this report is filed earlier I think the later one is much appropriate.
