Multiple login managers?

debuser · 03-26-2004, 09:55 AM

Hello

I have been successful in getting multiple X sessions on more than one virtual terminals. Now my question is, can I have two different login managers too? I would like kdm on vt7 and gdm on vt8. I have tried searching on google and everybody is only talking about multiple X sessions using the same manager. Is it even possible to have kdm and gdm running at the same time?

Thanks

xdm, kdm, gdm, all of them create an instance of X just like any window manager. Therefore it would seem to make sense that you could start them on different displays. I would imagine that if you look at perhaps their config files or on their command lines you can place them onto different displays.

Just shooting from the hip, maybe if you call gdm the same way you call xinit:

gdm -- :1

to start it on the second display.

What you are saying is right maybe...

I have kdm installed a smy default manager. To get multiple kdm sessions, I have changed my Xservers -

:0 local@tty1 /usr/X11R6/bin/X -nolisten tcp vt7
:1 local@tty2 reserve /usr/X11R6/bin/X -nolisten tcp :1 vt8

This gets me two login sessions without me typing anything after startup.

All I want now is kdm to start on vt7 and gdm to start on vt8 automatically...

Well, what is starting KDM? What I mean is, it looks like you've instructed X to start two sessions. So is X configured somewhere to, when it starts those X sessions, load KDM? And if so, could you make two seperate config files (one that tells X to start kdm) and one that tells X to start gdm and then in your lines specified above pass a specific config file to each instance?

Thanks jpbarto

You have given me a good lead. I now have to find how kdm starts up. My initial find was I found a file under /etc/X11 called 'default-display-manager' which has

/usr/bin/kdm

as the only line in it. So I am assuming when X starts up, it sees this file and starts up kdm. I have to do some reading and find more about this.

If I find a solution I will post it here.

Thanks

Just to give you another thought, I use GDM and it is started by my init scripts in /etc/rc.d (gdm then starts X for itself). My initial thought was you could create two init scripts (one kdm, one gdm) that start X for themselves each on their own display.

Again, just listing another possibility.

Good luck,
