Is it possible to install a desk environment without any integrated programs?

almost every desk environment has there own integrated programs.
sometimes I don’t need so many programs to be installed into my OS.
is it possible to avoid that?

Yes it is, but there are pro’s & con’s (there are reasons leafpad is used by LXDE, mousepad by XFCE, gedit by …).

This site however is for the co-ordination of the Ubuntu project, and not support.

For Ubuntu Support options, you’ll find many listed at https://community.ubuntu.com/t/finding-help/712
