(solved) Thanks.

At the login, I can select a few including KDE which is not present and another one that is not installed. But, I went through synaptic and if it was a window manager, I installed it. I want to try them all, but I don't know how to add them to the login screen so that I can"F1" to select them.

Is there another way to select the different window managers ? Also, can I edit that login scree so that options that aren't even installed no longer are there and the ones that I installed are ?

You will need to edit 2 files.

One is in your home user folder called .xinitrc
As user, just follow the syntax and add the correct exec command for your window manager. eg

openbox)
exec openbox-session
;;

Next you need to edit this line in /etc/slim.conf, as root. Again add what you want and remove what you don't want.

sessions icewm,xfce,fvwm-crystal,kde,openbox,fluxbox


The reason why there are options at login even though the wm/desktop environmants are not present, is to make it easier for those who install a differet wm/de.

Alternatively, you could just install gdm or kdm (comes with gnome/kde) and it will automatically add each wm/de to the login menu.

I like the ease of installing gdm or kdm, I think. The automatically does it part cinched it for me. Can I JUST install the gdm or kdm or do I have to have Gnome, KDE and all of the trappings that go along with it?

You will get some dependencies but not the whole of gnome or kde.

Try in a terminal, as root user,
apt-get update
apt-get install gdm
Choose N

then
apt-get update
apt-get install kdm
Choose N

to compare what will get installed. I think gdm will be a little bit smaller.

Just apt-get install gdm and it will take care of itself. You will have to monitor the install though because it will ask you which log in manager you want to use as only one can be used. Just select gdm and your golden.
