gnome-settings-daemon indeed crashes in that case, which breaks a load of things, including the desktop manager in general.
The reason for this is that when you restart the networking job, it kills off the system dbus bus, which brings down quite a lot of stuff with it. ** Package changed: ubuntu-meta (Ubuntu) => gnome-settings-daemon (Ubuntu) ** Changed in: gnome-settings-daemon (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1072518 Title: Restarting network crashes (apparently) the desktop manager Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: The unity UI and windows decorations dissappear when I do one of the following: sudo restart networking or sudo /etc/init.d/networking restart. This renders me unable to focus any of the open windows with mouse/keyboard, leaving the system unusable. I have to drop to terminal (CTRL-ALT-F2) and do a sudo reboot. I am not sure what parts of the desktop are going down, so I posted this bug under ubuntu-desktop. I'd be happy to follow up with more information as needed.
