At least part of this is ubuntu specific. The distribution patch lp341684_device_sensitive_disconnect_notify.patch
in the package network-manager-applet sets this notification importance to NOTIFY_URGENCY_CRITICAL. I can confirm that if you change this to NOTIFY_URGENCY_NORMAL, the notification disappears after the timeout Apparently, gnome-shell keeps on showing NOTIFY_URGENT_CRITICAL notifications, even if they are marked as "transient". The ubuntu- specific patch assumes the unity behavior. This is probably the cause of the bug. I'm marking network-manager-applet as affected. ** Also affects: network-manager-applet (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/883443 Title: GNOME Shell 3.2.0 falsely states: "Network Disconnected - you are now offline" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/883443/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
