What is the role of the desktop environment in the architecture of a Linux-based operating system like Ubuntu?
Can anyone explain what a desktop environment is and how it relates to other components of the system?

This isn't strictly specific about Ubuntu and I'm sure it has been answered here Unix & Linux StackExchange– Uri HerreraOct 1, 2012 at 22:34

@UriHerrera We allow lots of questions that also apply to other Unix-like operating systems. Furthermore, a good answer to this question could be posted, that addresses Ubuntu-specific aspects of the question. (For instance, it would be great to have an answer that explains what a desktop environment is and how Unity is not, contrary to what many people seem to believe, a desktop environment).– Eliah KaganOct 2, 2012 at 4:32

We could answer a question like this on Unix & Linux, but read the Wikipedia article first. IF you still have questions AFTER READING THE WIKIPEDIA ARTICLE, feel free to ask them on U&L.– Gilles 'SO- stop being evil'Oct 2, 2012 at 20:00

In nutshell,
The Linux Kernel runs on the hardware. (init and other essential processes start)
After essential processes are up and running, Kernel runs X-server (another set of software).
- Desktop environment such as Gnome, KDE, DWM runs using the facilities provided by the X.
Everything works in layered fashion.
