I'm just a newbie to Arch Linux. I heard it's pretty cool, but I am still learning the fine points of the installation.
I haven't gotten Gnome to work yet. X just runs the basic X windowing with a few console windows.
Update - I got KDE to work.
I could have done the same procedure with Gnome. Maybe I will try adding Gnome as an option later. Now the fun starts.
Update - I got GNOME working too.
