Running Ubuntu with multiple monitors having a panel each

Managed to fix it just now.

I did the following to create a new panel and move it to the secondary monitor:

1. Right click on existing panel and choose New Panel
2. Drag the new panel to the secondary monitor by ALT + Drag
3. Right click on your new panel and choose Add to Panel
4. From the list, choose Windows List

Wrote up a blog post about it here.
