How to restart the X server under Debian?

["Colin Finck" <mailinglist@colinfinck.de>]

Hello,

I need to restart the X server (XFree86 4.3.0) under Debian Sarge with a
script or program.
On other Linux systems, I now that I can use "init 3" to terminate the X
server and then use "startx" to start it again, but on my Debian system this
does not work.

Additionally I have no runlevel 5. On other Linux systems, this runlevel is
used for a graphical X environment, but on Debian it simply does not exist.
Is there a way to add this, because I want to autostart the X server after
login.

Many thanks in advance,

Colin Finck
