## 3. Installing The Display Manager (xdm)

The display manager makes your PC look like an X terminal. That is, it presents you with a login screen that runs under X.

The easiest way to automatically start the display manager on boot is to add a line in `/etc/ttys` to start it on one of the unoccupied virtual terminals:

> `

>      ttyv4	"/usr/X11R6/bin/xdm -nodaemon" xterm	on secure

> `

You should also make sure that `/usr/X11R6/bin/X` is a symbolic link to the Xserver that matches your video card or edit the file Xservers in `/usr/X11R6/lib/X11/xdm` to specify the pathname of the X server.

The change to `/etc/ttys` won't take effect until you either reboot or ```kill -HUP 1`'' to force initd to reread `/etc/ttys`. You can also test the display manager manually by loging in as root on the console and typing ```xdm -nodaemon`''.
