Runlevel4 and multi-users?
How can I have it so when I load up KDM in Runlevel4 that I can have one user run stuff, then have the processes continue, but end up letting users switch, so two users are using the processor, even though only 1 is on at one time? I'm also curious to know how I can do this while keeping the privacy factor available, where to get access to the other profile or user, you have to put in the user's password? Essentially, I'm wondering how to run something similar to Win+L on XP, but for Linux. I know that if I go to RL3, you can switch by hitting Ctrl+Alt+F1-6 or whatnot, but it doesn't have the same privacy as I'm looking for since no password is required to go back into the inital console.
