- Remove the top panel in gnome by right clicking and choosing 'delete this panel'
- Now right click on your bottom panel and select add to panel and select these 'menu bar', 'windows list', 'clock'..etc etc
- Now you will have one ubuntu icon(menu bar), place it on your extreme left by right click 'move'.
- Similarly arrange your rest of the icons and shortcuts in the panel.
But now the ubuntu logo is too small and it really doesnt look like a button and not at all a start menu ICON..so here's what you do
- Now to change the start menu icon press Alt+F2 and type gconf-editor
- goto apps->panels->objects.
- select object_x(e.g object_0 etc) and look out for entry 'object_type'. look for the one where 'object type' = 'menu object' . for me it is object_1, this may differ according to your settings.
- now once you are in the right object_x , tick on 'use_custom_icon' and add start menu button icon to 'custom_icon'(get loads at Gnome-look)
