If that file does not exist, then the first display manager found in alphabetical order
will be used.
Since init has been set up to respawn the display manager automatically, it is relatively
easy to load and test changes to the display manager configuration file??”just
kill the display manager! If you??™re using XDM or KDM, you can kill the display manager
by name:
# killall xdm
Killing the display manager will also kill all the display manager??™s child
processes, including X servers??”so if you do this through the graphical
interface, expect your session to disappear!
GDM is a wrapper script for gdm-binary, so if your system uses GDM, you??™d have to
kill the display manager with the following:
# killall gdm-binary
Alternately, you can restart GDM immediately using its restart script:
# gdm-restart
Or you can specify that a restart should take place as soon as everyone is logged out:
# gdm-safe-restart

is in /etc/ttys instead of /etc/inittab:
ttyv8 "/usr/sbin/xdm -nodaemon" xterm on secure
The fourth field can have a value of on or off to enable or disable the display
manager.
