Another piece of the puzzle: if you run: sudo fc-cache -fv
this will rebuild the system font cache in /var/cache/fontconfig If you then delete the user's cache in ~/.cache/fontconfig and re-log, there is no delay... and the user's font cache will NOT be rebuilt. After a delayed login, user's cache and the system cache appear to contain the same files. So it looks as if something thinks the system cache is out of date and wants to rebuild it. Whatever it is only has user permissions, so rebuilds the font cache in the user's .cache -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1754836 Title: Xubuntu: ERROR:dbus.proxies:Introspect error on org.bluez:/org/bluez: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.bluez': timed out (service_start_timeout=25000ms) Status in blueman package in Ubuntu: New Status in bluez package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Xubuntu seeing long first time boot to desktop from login.
