Ubuntu 9.04, two screen, but still one taskbar, and tasktray….
Solution: Right click on a bar, add New Panel, add New Panel, etc,… as many time as needed to reach the other screen. Remove the usless extra one.
Right click add to Panel on the new taskbar: Window Selector.
Reorganize all you applet, sound etc…
Now you’ve got a wonderful one meter long desktop, with taskbar linked to the display desktop.
