Does anyone know what this is about, and how to fix it?

[28358:1008/184025.188520:ERROR:object_proxy.cc(590)] Failed to call method: org.freedesktop.portal.Settings.Read: object_path= /org/freedesktop/portal/desktop: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.portal.Desktop was not provided by any .service files

-- while we're at it, can we modify base code to start up with the mesa-loader error disabled?

Thanks!
