Hai, though i am 70% confirmed in using GNOME environment, but bit doubtful regarding, “Whether iam using Gnome or Kde desktop environment in Fedora 14”
To check it, did a bit surfing and confirmed with GNOME.
You can verify it using gui or terminal
On Fedora, form the top panel click on System -> About this Computer. Now you can see GNOME or KDE with its version number
On Ubuntu, you can find directly as System -> About GNOME or System -> About KDE
Type the following command in the terminal.
You can see the output as gnome (if gnome present) or kde (if kde present)
