Does it help for a Linux system to have multiple desktop environments installed?
Having only one or multiple desktop environments installed is primarily a personal choice of the user. It does not really matter other than to the user’s personal preference. Some users may prefer to have only one environment installed, such as KDE or Gnome. Whereas, others might prefer to load more than one in order to take advantage of the fact that the system allows switching from one environment to another. However, it should be noted that some programs may work on one environment and may not work on the other.
