Tasksel really makes it very easy to install desktops in Debian. Running it is as simple as typing
tasksel on a root shell where you would be offered a nice UI to select and install desktop of your choice.
In case you wonder how is it possible to install desktops by a simple choice, its made possible by the task packages which you can also manually install.
- apt-get install task-kde-desktop
- apt-get install task-lxqt-desktop
- apt-get install task-mate-desktop
Those above tasks will install desktop of your choice. There are also localised special tasks available.
- apt-get install task-telugu-gnome-desktop
This should install Gnome Telugu.
Other tasks also exist for special purposes like
education-tasks for customised desktop with packages for education.
