I have seen it either go to the blank u-s-c screen or back to the Unity 8 greeter. I don't have a crash file nor have I seen any interesting info in the unity8.log. If downgrade qtmir to 0.4.6+16.04.20151119-0ubuntu1 and unity 8 to 8.11+16.04.20151112.1, the issue no longer occurs. When I get the blank u-s-c screen, I do see this in the application log: [1449081140.172725] <ERROR> MirSurfaceAPI: Caught exception at client library boundary (in mir_surface_release): /build/mir-sTjxjQ/mir-0.17.1+16.04.20151105.1/src/client/rpc/stream_socket_transport.cpp(168): Throw in function virtual void mir::client::rpc::StreamSocketTransport::send_message(const std::vector<unsigned char>&, const std::vector<mir::Fd>&) Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<mir::socket_disconnected_error> > std::exception::what: Failed to send message to server: Broken pipe 32, "Broken pipe" terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<mir::socket_disconnected_error> >' what(): Failed to send message to server: Broken pipe To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-pocket-desktop/+bug/1522117/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
