I am using my machine with multiple accounts logged in at the same time. I am using KDM desktop manager and KDE desktop. Ever since I upgraded to Karmic, when using one user the second user, who is active on another virtual terminal, gets logged out automatically. I have looked through the logs and can't find anything that would cause this.

What should I be looking into to figure it out? Is there some sort of feature that was turned on through the upgrades? (the machine has been through many releases..).

You can check that you have enough TTY's:

Open a terminal and do:

grep tty /etc/default/console-setup

It should show (check the last number, it should say 6):


If not, edit the /etc/default/console-setup file by typing:

gksudo gedit /etc/default/console-setup

And look for ACTIVE_CONSOLES, and make the line look this:

In the end I lived with this for a while and ended up upgrading Ubuntu to a newer version and it went away. So not sure what it was but probably a bug somewhere..
