Changing the display manager

If you wanted to change the display manager you could try stopping the current one and starting the one you want. For instance, if you wanted to stop using kdm (KDE desktop manager) and start using gdm (Gnome desktop manager) you might try the following:
/etc/init.d/kdm stop
/etc/init.d/gdm start
However, this gives an error along the lines of:
Not starting GNOME Display Manager (gdm); it is not the default display manager
To make gdm the default display manager you need to edit the file /etc/X11/default-display-manager. This file should only contain one line - the full path to the desktop manager you want to run. In the previous example the file would contain /etc/init.d/kdm. So I would change it to /etc/init.d/gdm. Now when you type the original commands the Gnome desktop manager will start.
