<p><strong>From Milton L. Hankins on Mon, 30 Mar 1998 </strong></p>
<p><strong>
Actually, it sounds like Cesar's <tt>.xsession</tt> script is exiting before he
performs his usual "logout" action.</strong></p>
<p><strong>Cesar, does the user account have a <tt>.xsession</tt> file in the
home directory? If not, create one. The simplest one would contain the
line "<tt>fvwm</tt>" or "<tt>xterm</tt>".</strong></p>
<blockquote><img src="../gx/dennis/bbub.gif" width="50" height="28" alt="(!)"
align="left" border="0">Milton,
<br><br>
Wouldn't this show up as a problem when he ran '<tt>startx</tt>' as well?
<br><br>
As I've said before my practical grasp of X is pretty weak -- but
I do understand the concept of a '<em>session manager</em>.' Most X clients
in your start up script are started in the background (with trailing
ampersand in shell script syntax). However one (usually the last
item executed by the script) must be started in the "foreground."
This client, whether it is a window managers, an '<tt>xterm</tt>' or even
'<tt>xclock</tt>'
will be the "session manager." When you exit or kill the session manager
the X server takes that as a hint to close down (returning you to a shell
prompt if you used '<tt>startx</tt>' or to an <tt>xdm</tt> login screen
if you started the session graphically.
<br><br>
Can you clarify the differences between <tt>~/.xsession</tt> and
<tt>~/.Xclients</tt> (mine are just symlinked together)?

<blockquote><img src="../gx/dennis/bbub.gif" width="50" height="28" alt="(!)"
align="left" border="0">Not necessarily, Jim. It all depends on the
system scripts. Traditionally, <tt>startx</tt> uses "<tt>~/.xinitrc</tt>"
and <tt>xdm</tt> uses "<tt>~./xsession</tt>".
<br><br>
It sounded like he was only having problems as a "normal user" -- that
root was OK. You obviously know a lot more about <tt>xdmi</tt> than I do,
but I went on a hunch that his <tt>xdm</tt> setup was fine.

difference between an X client and an X server means you know something.)
<font color="#008F00">:)</font> That's what I meant by "usual `logout'
action." Most people either logout of a special xterm or exit the window
manager. </blockquote>

strange. Usually, I link <tt>.xsession</tt> and <tt>.xinitrc</tt> together.
That way, X looks the same whether I use <tt>xdm</tt> or <tt>startx</tt>.
