How do I tile windows side by side?

On the site http://ubuntued.info/como-por-as-janelas-do-ubuntu-lado-a-lado is possible to place the windows side by side with the gnome-do, but this tool does not work in the new Ubuntu 11.04 Natty Narwhal. How do I make this work in the new ubuntu?

Solution 1:

I would also recommend for a day or so you use this really really good guide which shows you how to use some of Unity's features to the maximum

It was created by Octavian Damiean and I have found it very useful. When you have memorised all of it ;) you can go back to your favourite wallpaper

Here is the link for it if the image does not work

Solution 2:

install compiz-fusion-plugins-extra .The defaults in Ubuntu 11.04 involve Upper Left Corner, Left Edge, and Lower Left Corner being set to Left Half, and Upper Right Corner, Right Edge, and Lower Right Corner being set to Right Half.
