.xinitrc for XFce patch suggestion

[Ric]

Hello Benedikt:

Thank you for your insight.  I was unaware that  pidof  was
not  in most *nix.  

For XFce4, how about just a simple:

# Launch xscreensaver (if available)
if [ -x /usr/X11R6/bin/xscreensaver ]
   then	                             ## XSS exists
     if [ $UID -gt 0 ] 
   	then	                     ## root is not logged in
        xscreensaver -no-splash &
    fi
fi

I did a little testing here and that resolves the basic
problems since XSS will not be asked to start when $UID<=0.
  Do you think it might be better to use a test  $UID != 0 
?
Of course, the above only works as is for sh compatible
shells = bash.  I do not know what the current shell is for
other *nix.  I thought sh and bash were generally the
standard for all the *nix but I had not given much thought
to it before.

As for the distributed X, I do not have experience there,
yet -have not had the need to do it.   I guess you are
saying that someone could be root login on one machine that
serves X & XSS to other systems and because they are root
on the X server, when the other system does startxfce4,
they will not get a xscreensaver running (or vice-versa)...
 ???
That is a bit confusing to me as I do not see why sh would
assume the server's login identity for the remote system
for the .xinitrc file but again, like I said, I have 0
experience serving X to other systems.

I am trying...

Have A Great Day!
