I am sorry, but there are some bug in the X11R6.08Sept95 distribution:

1. This bugs are for xdm which I normally don't use:

    - /usr/local/X11R6/lib/X11/xdm/Xscript needs an
      at the begining of it or xdm can't even start.

    - xdm is broken and has a SECURITY HOLE in it, that means that every
      one has root privileges !
      PLEASE use the new xdm in X11R6.08Sep95-xdm.tar.gz

      gzcat X11R6.08Sep95-xdm.tar.gz | (cd / ; tar --unlink -xfp -)

    - Xsetup, which is a script to execute some programms, e.g. xmodmap to
      change the keymap, needs an extra line in
      to use it:

      DisplayManager*setup:              /usr/local/X11R6/lib/X11/xdm/Xsetup

     and /usr/local/X11R6/lib/X11/xdm/Xsetup look like this:

     xmodmap /usr/local/X11R6/lib/X11/german.xmodmaprc

    But don't forget to make this script executable:

    chmod 555 /usr/local/X11R6/lib/X11/xdm/Xsetup

2. Xcl and Xamiga24 doesn't come up in mono with the supplied xserverrc and
   Please add an ' -dev /dev/grf0' after the '-mono' option in it

Many thank to Blaz Zupan <> for sending me a bugreport
about this problems.
