On my Debian Linux no Login is possible on terminals 2 to 6. Login on 1 works fine, xorg-session with XDM and awesome wm works, too.
The Error Message shown on these 5 screens is:
systemd-logind[...]: Failed to issue Method call: Launch Helper exited with unknown return code 1
I don't even know how to start solving this. How can I make these terminals working?
