13.3. Escritorios gráficos
The free graphical desktop field is dominated by two large software collections: GNOME and Plasma by KDE. Both of them are very popular. This is rather a rare instance in the free software world; the Apache web server, for instance, has very few peers.
This diversity is rooted in history. Plasma (initially only KDE, which is now the name of the community) was the first graphical desktop project, but it chose the Qt graphical toolkit and that choice wasn't acceptable for a large number of developers. Qt was not free software at the time, and GNOME was started based on the GTK+ toolkit. Qt has since become free software, but the projects still evolved in parallel.
The GNOME and KDE communities still work together: under the FreeDesktop.org umbrella, the projects collaborated in defining standards for interoperability across applications.
Elegir «el mejor» escritorio gráfico es un tema sensible que preferimos evitar. Simplemente describiremos las muchas posibilidades y proveeremos algunas ideas para considerar. La mejor opción es aquella que tome por su cuenta luego de un poco de experimentación.
Debian Stretch includes GNOME version 3.22, which can be installed by a simple apt install gnome (it can also be installed by selecting the “Debian desktop environment” task).
GNOME is noteworthy for its efforts in usability and accessibility. Design professionals have been involved in writing its standards and recommendations, which has helped developers to create satisfying graphical user interfaces. The project also gets encouragement from the big players of computing, such as Intel, IBM, Oracle, Novell, and of course, various Linux distributions. Finally, many programming languages can be used in developing applications interfacing to GNOME.
For administrators, GNOME seems to be better prepared for massive deployments. Application configuration is handled through the GSettings interface and stores its data in the DConf database. The configuration settings can thus be queried and edited with the
gsettings, and
dconf command-line tools, or by the
dconf-editor graphical user interfaces. The administrator can therefore change users' configuration with a simple script. The GNOME website provides information to guide administrators who manage GNOME workstations:
Debian Stretch includes version 5.8 of KDE Plasma, which can be installed with apt install kde-standard.
Plasma has had a rapid evolution based on a very hands-on approach. Its authors quickly got very good results, which allowed them to grow a large user-base. These factors contributed to the overall project quality. Plasma is a mature desktop environment with a wide range of applications.
Since the Qt 4.0 release, the last remaining license problem with KDE software has been solved. This version was released under the GPL both for Linux and Windows (the Windows version was previously released under a non-free license). KDE applications are primarily developed using the C++ language.
Xfce is a simple and lightweight graphical desktop, which is a perfect match for computers with limited resources. It can be installed with apt install xfce4. Like GNOME, Xfce is based on the GTK+ toolkit, and several components are common across both desktops.
Unlike GNOME and Plasma, Xfce does not aim to become a vast project. Beyond the basic components of a modern desktop (file manager, window manager, session manager, a panel for application launchers and so on), it only provides a few specific applications: a terminal, a calendar (Orage), an image viewer, a CD/DVD burning tool, a media player (Parole), sound volume control and a text editor (mousepad).
Another desktop environment provided in Stretch is LXDE, which focuses on the “lightweight” aspect. It can be installed with the lxde meta-package.
