Hi there, if are facing dead tmux session on ssh exit issue on raspberry, here it requires libpam-systemd, which is not included by default in minimal Jessie. I rebooted to enable it, but you may only have to relogin and / or restart systemd-logind.service. Install it with command apt-get install libpam-systemd

systemctl –user status

output (without libpam-systemd): Failed to create bus connection: Connection refused

output (with libpam-systemd):
