The problems I had when I started writing the initial draft that David
has now adapted is that older versions of gdm and kdm both did seem to
use the xdm-config files from what I remember.  My old SuSe box did (I
believe anyway).  It is all sort of blurring together. 

If you know which configuration files each version of each dm uses, let
us/me know.  It will definitely simplify things.  I started doing it by
distribution/OS version but it may need to be based on dm/version to
show what configuration files each uses.  Then each dm/version section
could just reference the files that it uses.  The file section could
then just explain what needs to change for that file alone.

I didn't (and still don't) have all knowledge and just started throwing
it together as I got it working.  Now as xinetd comes into play with
more of the distributions, it adds one more twist to an already tangled
mess.  Also, as the dm's progress, they seem to be going to their own
set of config files.  For example, the kdmrc file for kdm in the Debian
(woody-testing) version I could NOT get to work at all with Xvnc (grey
screen only).  My guess is that the version of kdm it was using at the
time was still trying to reference the xdm-config or other xdm files and
because they weren't there, it didn't work right.   That is my take.  I
got gdm working the first time.

All suggestions are welcomed and appreciated and thanks for the other
corrections.  That is what this was intended to do, get input and
refinements to make it start to crystalize into a really helpful
document.  It sure beats trying to muck through a search of the list
archives.

There are some confusions which aren't that bad, but which should, IMHO
be
avoided

In the section about gdmconfig
  3)
  b) If running Gnome as your desktop, ...

It doesn't matter whether your desktop is gnome, kde, icewm or
whatever. What
matters is whether you use xdm, kdm or gdm as display manager. Thus
this should
be changed in "If running gdm as your display manager, ...".
(nb: in fact in the redhat, in the basic configuration the display
manager and
the desktop are the same, as they are both set up by
/etc/sysconfig/desktop or
something like that).

- some settings seems to be valid for all the configurations, but it
isn't
true. For example, 

2) edit 'xdm-config' and comment out the line '!
DisplayManager.requestPort: 0'
(should be the last line)

hasn't any impact on the gdm settings. I think it should be made more
clear. I
put here a summary of what is needed for the display managers I know:

xdm: 2) and 4)

2) edit 'xdm-config' and comment out the line '!
DisplayManager.requestPort: 0'
(should be the last line)
                     a) RedHat 6.2, 7.1, 7.2 -
'/etc/X11/xdm/xdm-config'

4) edit Xaccess and uncomment the line '*        #any host can get a
login
window' 
                             a) RedHat 6.2, 7.1, 7.2 -'
/etc/X11/xdm/Xaccess'

gdm: 3) b)

I have never used kdm, but I have heard on another mailing list that
for old
versions of kdm, the config files used are the same than for xdm (point
2) and
4)) and that for new kdm there is a kdmrc file, as stated in 3) a).


Changing config for applications you don't use isn't such a big deal,
but I
think it may confuse things.


Last, I think it should be fine if, in addition to explaining how to
set up gdm
to accept xdmcp with gdmconfig, there was also a explaination on how to
do it
manualy, like

"edit /etc/X11/gdm/gdm.conf and in the [xdmcp] section, put
"Enable=true" and
"Port=177""



It is only suggestions, now, do what you want !
