I just install Centos 4.4 without GUI (X.org) nor KDE / Gnome selected only minimal system plus development and utility packages but somehow Redhat / CentOS install X.org by default and select KDE as it's Desktop Manager (although only kdebase packages installed). When the first I saw KDE I thought I had select the wrong packages, so I re-install my server. But the same thing happen. When I confirm this behaviour to my colleague, he said yes it will install X and KDE even you not select it. I didn't experience it when I am installing Centos 4.2. Well this is a step forward for Redhat / CentOS. Luckily my server has plenty of RAM installed so I don't have to worrying about sort of memory. Although I can setup my server to use init 3 directly from the start. LOL. This feature reminds me of Mandrake 8/9/10 when I am not selecting any X.org/KDE/GNome, it'll install X with IceWM for a simple GUI usage. Bravo Centos/Redhat
Other thing when I try a fresh Fedora Core 6. On Gnome there is a feature called Desktop Enhancement. When I activated this feature. Window behavior seem so flexible when you maximized or minimized it and also when you press Alt-Tab to change window it'll display a screenshot of a selected window. And when you want to change Desktop from Desktop 1 to Desktop 2 and so on... the desktop seems rotating from left to right or otherwise. And this the fun part (I think) you can drag a window from one desktop to another. Whahwwhahha... First I saw this I laught very loud. Because I never think of a Linux which seems to me so stiff can be so flexible like that. Good... good... I'll upgrade my Fedora Core 4 into 6 if I have some free time.
