Hi there Thomas, thanks for your detailed information so far. I also am unable to reproduce this myself. However from the stacktrace you supplied, I see the crash is happening during dbus traffic. I suspect these errors are vital:
[WARNING] Object::connect: No such signal QDBusAbstractInterface::activeChanged(bool) in /build/buildd/unity-2d-5.10.0/libunity-2d-private/src/dashclient.cpp:72 [WARNING] Object::connect: No such signal QDBusAbstractInterface::alwaysFullScreenChanged(bool) in /build/buildd/unity-2d-5.10.0/libunity-2d-private/src/dashclient.cpp:74 [WARNING] Object::connect: No such signal QDBusAbstractInterface::screenChanged(int) in /build/buildd/unity-2d-5.10.0/libunity-2d-private/src/dashclient.cpp:76 [WARNING] void DashClient::connectToDash(): Fetching Dash.active property failed [WARNING] void DashClient::connectToDash(): Fetching Dash.alwaysFullScreen property failed [WARNING] void DashClient::connectToDash(): Fetching Dash.screen property failed [WARNING] Object::connect: No such signal QDBusAbstractInterface::activeChanged(bool) in /build/buildd/unity-2d-5.10.0/libunity-2d-private/src/hudclient.cpp:71 [WARNING] Object::connect: No such signal QDBusAbstractInterface::screenChanged(int) in /build/buildd/unity-2d-5.10.0/libunity-2d-private/src/hudclient.cpp:73 [WARNING] void HUDClient::connectToHud(): Fetching HUD.active property failed [WARNING] void HUDClient::connectToHud(): Fetching Hud.screen property failed Some properties like Dash.active and HUD.active are shared between the panel & the shell via dbus (when Dash/HUD open, panel reacts). These errors imply that something is broken with this property sharing. I need to dig more to determine what could be going wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993694 Title: unity-2d does not start if user has logged in on unity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-2d/+bug/993694/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
