Sorry for the late responce, I was on an vacation....
anyways, it says:
Linux "Username" 188.8.131.52-35.fc15.i686 #1 SMP Wed Jul 6 14:46:26 UTC 2011 i686 i 686 i386 GNU/Linux
I'm sorry, that command was wrong. Unless you specifically changed the default install to use KDE and not Gnome, your probably using Gnome. One quick way is to look at the desktop. Default KDE has it's panel and icons on the bottom of the screen, Gnome3 has its panel and icons on the top. I'm sorry but at work I can't post screenshots, they're on my computer at home.
