So, All Debian Gnu/Linux lovers, go ahead and feel the G3 goodness. G3 is very beautiful and unobtrusive. If you are interested in a little G2 way, like menus, a task bar at the bottom, then I would suggest you the official plugins hosted by the G3 devs. And installing the extension is a breeze. Just remember to open the website with a firefox(iceweasal) based browser. And one more thing, disable any other composting manager you had installed. It will conflict with the composting which is a part of G3.
Thanx to the Debian GNU/linux devs for packaging the ati propreitory drivers in a workable package. And thanx go to the G3 devs and the community for an excellent DE with the added luxury of extensions which is growing day by day.
