Today I installed a Debian (etch) system from scratch and wanted to start a X server... hm ... no X server on a fresh installation. So what packages do I have to install to get a X server running on my system?
apt-get install x11-common xserver-xorg-core xserver-xorg xfonts-base xterm
If you prefer a small and fast window manager and no desktop like KDE or Gnome try out enlightenment.
apt-get install enlightenment
