I suggest to use to volume-applet way of displaying tooltips. Volume Applet <b>Out: xx%</b> {volume in dB} {device name} nm-applet Network Manager <b>Network: {network name}</b> {signal strengh} % "Time connected: {uptime}" or "IP: {ip}" or "Speed: {speed}" Power Manager gnome-power-manager <b>Battery: {batery} %</b> Time available: {h} {m} Battery Status: {capacity}% - Good. -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
