I get [+0.01s] CRITICAL: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
in the logs (or when running in test mode). This only happens when trying to run under Mir. Meaning I can delete 51-unity8-greeter.conf and lightdm starts just fine. The error happens before usc/mir are able to log anything. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1583624 Title: Mir cannot open a tty when started by lightdm Status in Light Display Manager: In Progress Status in Light Display Manager 1.18 series: In Progress Status in lightdm package in Ubuntu: Triaged Status in lightdm source package in Xenial: Triaged Bug description: From mir-greeter.log (and with minor instrumentation from RAOF) ERROR: QMirServer - Mir failed to start qtmir.screens: ScreenController::ScreenController qtmir.mir: MirServer created qtmir.mir: Command line arguments passed to Qt: ("/usr/bin/unity8", "--mode=greeter") ERROR: /home/josh/Documents/mir/verbose-error-for-vt-finding/src/server/graphics/default_configuration.cpp(133): Throw in function mir::DefaultServerConfiguration::the_graphics_platform()::<lambda()> Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> > std::exception::what: Exception while creating graphics platform ERROR: /home/josh/Documents/mir/verbose-error-for-vt-finding/src/platforms/mesa/server/kms/linux_virtual_terminal.cpp(238): Throw in function int mir::graphics::mesa::LinuxVirtualTerminal::find_active_vt_number() Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> > std::exception::what: Failed to find the current VT.
