Title:
Calling "service networking restart" kills unity
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
Note: I am not sure if this is an issue with unity, with compiz, or
with some other component such as dbus, or if it is multiple bugs.
At work I use a bridged network interface (br0) over eth0 on my laptop
to seamlessly connect my laptop and its virtual machines to the
corporate network. As Network Manager cannot handle bridged
connections, I am forced to use the old /etc/network/interfaces file
to configure the bridge. (Note that I removed all network manager
entries that reference eth0 before creating the bridge.)
This setup worked fine in 12.04 and earlier versions. I was able to
reconfigure the bridge (when necessary) and restart it using the
command line without issue using those releases. When my computer is
booted with the bridged configuration, 12.10 uses the bridge to
connect to the network without issue. The problem occurs only when I
restart networking.
In 12.10, issuing the command "sudo service networking restart" or
"sudo /etc/init.d/networking restart" causes Unity to instantly and
completely die. The compiz window manager decorations disappear and
do not restart, keyboard shortcuts do not work, services such as
bluetooth become unresponsive. Existing windows remained (without
window manager decoration) on the screen, but appeared hung. With a
USB mouse I was able to move the mouse and right click to open menus,
but they were unresponsive to clicks. I was unable to do anything in
Unity to correct the situation. I was able to switch to a virtual
terminal (Ctrl+Alt+F1) and log in to the command line. From there I
was able to restart the computer.
I have been able to replicate this consistently.
I am attaching my .xsession-errors file. Note that the entries up to
and including line 110 were made before issuing the network restart
command. Entries after 110 resulted from issuing the command.
