I've in my laptop Ubuntu 12.04.03 which comes by default with Unity.

I like Unity, and Gnome. It has a nice look, some nice apps, things frequently works nice.

However I would prefer to use Openbox. It is very lightweight, the 'context menu' is fantastic, and so on. But some times Openbox sucks, for instance, the wallpaper does not appear no matter what I do, the backlight also isn't working, etc..

I read somewhere that it is possible to run openbox and gnome together. My question is: what are the pros and cons of doing this? In my laptop in GDM when I log using Gnome/Openbox seems that there is no difference between the conventional Gnome environment. If I use openbox+gnome would I be able to use the right-button mouse click context menu?
