use VMware player to install Gnome and KDE
Gnome. If you want KDE, you can use Kubuntu, the KDE derivative of Ubuntu.
Ubuntu - GNOME Kubuntu - KDE Xubuntu - Xfce Puppy Linux - JWM Damn Small Linux - JWM, Fluxbox Fedora - GNOME (default) OpenSUSE - KDE (default) Debian - GNOME, KDE, Xfce Red Hat Enterprise Linux - GNOME Linux Mint - GNOME Xandros - KDE PCLinuxOS - KDE
Gnome There is a KDE version named Kubuntu, however
Everything will still work. However gnome applications do not interact with the desktop environment of KDE as well as they would with gnome. The differences will be mainly superficial. You can always remove the gnome applications later and replace them with kde ones if you want.
Ubuntu uses GNOME by default. However, a KDE version is available, named Kubuntu. It doesn't have all the bells and whistles of its GNOME counterpart
There are many desktop environments in linux. Most prominent would be: KDE Trinity - KDE fork (response to KDE 4.0 dissatisfaction) Gnome MATE - Gnome fork (response to Gnome 3.0 dissatisfaction) Cinnamon - Gnome fork (response to Gnome 3.0 dissatisfaction) Unity - Ubuntu's desktop environment (built on top of Gnome 3.0) XFCE LXDE There are many more. Also, there are window managers that have comparable functionality (ex. Enlightenment)
there are too many Gnome, unity, kde, ....
Yes. Both are fine.
GNOME and KDE.
KDE and GNOME are the result of two different attempts to create a free and open-source desktop environment for Linux. KDE was created first. KDE used a widget toolkit known as "Qt", which was not open-source back then. Since some users wanted one that was completely open-source, even the toolkit, the GNOME project was created. Many users still liked KDE, though. Those who did not want to switch stuck with KDE. Those who insisted on free software chose GNOME. Later, the Qt toolkit was open-sourced, which removed much of the incentive for GNOME to exist, but enough users at that point like GNOME better, so development has continued.
