Hello. I am using Linux Ubuntu v.11.10 64-bit operating system.
I have been hearing much about KDE, LMDE, and XFCE in relation to GNU/Linux; more specifically in terms of Debian and Ubuntu? I am trying to understand what 'exactly' these three (and maybe more similar) to these similar acronyms (I think?) are?
I am a newbie to GNU/Linux. As I am learning more about GNU/Linux systems, these acronyms (I believe to be.) I have been learning that these acronyms (Again, I believe.) have been becoming popular in online discussions in the recent year. These acronyms (I believe.) are being raised by proficient Linux users. These same Linux users are encouraging other Linux users to go to them instead of Ubuntu because of 'a better experience' as these same Linux users dislike the new Unity GUI that Ubuntu has incorporated into the Ubuntu programming this past year. These Linux users use these acronym like names with ever sharing what they are in online discussions.
What 'exactly' are KDE, LMDE, and XFCE precisely? Are they a different graphical environments? Are they a separate project from whatever it relates to in terms of the GNU/Linux systems? Where does KDE, LMDE, and XFCE fall under the grand scheme of things of GNU/Linux? Please explain.
Also, IF it IS a acronym for an formal proper name of another GNU/Linux system, then how many more 'acronyms' exist for other GNU/Linux formal proper names are out there? Is there an online chart or table with references between the acronym and the proper formal name you can refer me to?
