Hi all.

First of all, let me explain "why would someone wan to use an old gdm
version in the newest openSuse".

Our aim here is to make opensuse 11.2 multiterminals. Yes, it's
possible to make such a thing using simply XOrg and kdm, BUT there I
fall in the limitation of having just one terminal for each video
card.

We want to have a terminal for each video output available (two per
video card). That can't be done with only XOrg. For that to work, I
also need something like Xephyr or XNest. Preferably Xephyr since it's
still in development, and have some "new stuff" available.

Unfortunatelly, I'm trying for some time already to open more than one
independent Xephyr section for each video card with kdm, editing kdmrc
file, and I'm beggining to think that it can't be done. This feeling
is also reinforced by the following information
(http://en.wikibooks.org/wiki/Talk:Multiseat_Configuration/Xephyr):
"No analogue for flexible=false in kdmrc - impossible."

That, of course, drives me back to gdm. What on one hand is great,
since basically ALL tutorials using Xephyr uses solely gdm instead of
kdm. Unfortunatelly, as the GDM manuals online also states
(http://library.gnome.org/admin/gdm/2.24/gdm.html), "GDM 2.20 and
earlier supported the ability to manage multiple displays with
separate graphics cards, such as used in terminal server environments,
login in a window via a program like Xnest or Xephyr, the gdmsetup
program, XML-based greeter themes, and the ability to run the XDMCP
chooser from the login screen. These features are did not get added
back during the 2.22 rewrite."

So, here is my problem: I can't use XOrg solely, because it can't deal
with independent displays for each video output, just for each PCI
Address. So I have to use Xephyr. But it seems that I can't also use
Xephyr with KDM, So I have to use GDM. Unfortunatelly, I also can't
use GDM versions newer than 2.20, So I have to use the GDM that comes
with openSuse 11.0. There is a version available for 11.1 from M4rk
repository, but no one still for version 11.2.

I tried to install, via one click, the gdm from 11.0 on my 11.2. The
installation was smoothly. When I changed from kdm to gdm, however,
the restart fails with the following error message (taken from
/var/log/messages file):

Dec  8 15:47:47 windu gdm[2285]: GLib-CRITICAL: g_key_file_get_value:
assertion `key_file != NULL' failed

It appears several times. :(

Anybody has a clue here? Be it how to avoid this error message, how to
use Xephyr into kdmrc file, another desktop manager, whatever? Or do I
have to step back, surrender and use openSuse 11.0? :(

Thanks a lot in advance for any help! :)

Sincerally yours,

Jones
