Панель Gnome и терминал не работают на VNC

У меня есть экземпляр Ubuntu 16.04 на AWS EC2. Я установил vnc4server, рабочий стол ubuntu и панель gnome в удаленный графический интерфейс.

Когда я подключился в первый раз, все было в порядке, но после перезапуска экземпляра элементы gnome не запускались (верхней панели нет, и я не могу открыть терминал gnome).

Это мой конфиг xstartup:

export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal &

И мой лог имеет это отупуть:
