How do I enable multi-row layout for the workspace switcher applet in Metacity?

I'm looking for a way to increase number of rows in workspaces layout, using Metacity with no Compiz installed.

i.e. 3 cols and 2 rows. Using gconf-editor I can only change number of workspaces horizontally, but not vertically, even if it seems to be possible.

I'm working on a Ubuntu 11.04 machine with classic Gnome.


Solution 1:

The key you are looking for is
