You might be running into those dbus blocking calls in the network-manager bearer backend. The networkmanager bearer plugin currently is using a few blocking dbus calls to get properties and such. see this abandoned change here: https://codereview.qt-project.org/#/c/98090/
This change was abandoned as QNAM is synchronous in nature, and expects defaultConfiguration to be ready right away. I have written a simple bearer backend plugin based on the connectivity-api that might be used instead. This has one static configuration that it used. https://codereview.qt-project.org/#/c/140752/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480877 Title: Access points' "PropertiesChanged" dbus signals freeze UI on mobile devices To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1480877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
