Oke. X with a xterm is perfect.
What i want to test is start firefox in:

X11
KDE
Gnome
and Openbox

than i want to determine where the resizing of windows is starting to
get slow and than do some further research to find the cause. So how
do i start a X with just xterm? when i run: "startx" than i'm just
getting the default login manager

Ad how would that work if i want ot set it to SLiM? (http://slim.berlios.de/)
and that file is not existing.. is there a file with the defaults
somewhere? must be.. X isn't getting GDM out of thin air.
