I'm seeing slightly different symptoms. My nm-applet reports that there are no network devices and I can't enable networking. Sometimes it also says that network-manager is not running. It started today and luckily I still get Ethernet although wifi is completely down.
I don't see the extremely bad responsiveness though. I'm using Lubuntu Precise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/956238 Title: network-manager is almost unusable since the latest update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/956238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
