Hi all,

I want to be able to start a second X session out of my current session. I know this question has been raised several times, and the start itself is not my problem. I have multiple entries in the Xservers files, and the second session comes up. No problem.

But I am already logged in as the user under which I started the session.

What I want is to start the new session as root (e.g. via some SUID program), and want the kdm login screen to appear so that I can choose which user and session type I want to start the session under. And I want to be able to do this out of any session type I am currently running (kde, gnome, xfce...)

Any idea how to achieve that?

I found it on http://people.fruitsalad.org/lauri/stuff/README: kdmctl reserve <timeout in seconds> This command can be launched from anywhere, any session. Mario
