(*** This bug was imported into bugs.kde.org ***)

Package:           kdm
Version:           unknown (using KDE 2.1.2 )
Severity:          wishlist
Installed from:    Red Hat Linux 7.1
Compiler:          gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)
OS:                Linux 2.2.17-8smp i686
OS/Compiler notes: 

KDM should have the ability to log in multiple users simultaneously.

Example scenario:

A user having logged in via KDM  is working on a KDE desktop. User B wishes to do work. User A does not wish to close his open apps or stop work.

Currently

1. User B switches to a virtual terminal

2. User B runs `startx -- :1' or something similar.

3. User B finises work logs out of KDE logs out of his VT and then must switch back to user As desktop

Ideally

1. User A clicks `log on as another user'. The system switches to a *seperate* VT where KDM is running

2. KDm shows that user A is currently logged on. User B logs on and works.

-------------

Such a system should make sure that users from other VTs cannot access other  users desktops without a password.

It should be possible to disable for machines with small amounts of RAM.

Version:           KDE 3.0.0 
Installed from:    RedHat RPMs
Compiler:          gcc-2.96-110
OS:                Linux
OS/Compiler notes: redhat 7.3

I had attempted to run three different Xservers on my machine in order to allow multiple X logins at once.  This worked fine under gdm however when I decided to switch to kdm this failed.  Some of the problem appears to be because of a .pid problem.  The original kdm instance places a .pid file in /var/run/.  Other kdm instances which are trying to connect to different screens see this .pid file and refuse to run.  Perhaps changing the .pid file to reflect the screen name could fix this?  
Another part of the problem appears to be that the original instance dies unexpectedly therfore no kdm instances not even the original :0 screen runs.
