Prevent Logoff from Killing tmux Session












9














I have noticed that a logoff (log out) from my X user session will kill any tmux session I have initiated, even sessions I had run with sudo tmux and similar commands. I am sure that this formerly did not happen, but some recent change has effected this behavior.



How do I maintain these tmux (or screen) sessions, even after I end my X session?

This "feature" has existed in systemd previously, but the systemd developers decided to effect a change in the default, to enable the setting for termination of child processes upon log out of a session.



You can revert this setting in your logind.conf (/etc/systemd/logind.conf):



KillUserProcesses=no


You can also run tmux with a systemd-run wrapper like the following:



systemd-run --scope --user tmux


For these systems, you may just want to alias the tmux (or screen) command:



alias tmux="systemd-run --scope --user tmux"

    … and in many other places. In the Debian bug that that refers to, I explained how one could actually make systemd-logind do the right thing. bugs.debian.org/cgi-bin/bugreport.cgi?bug=825394#221

  • @JdeBP Thanks for telling us that sending SIGHUP instead of SIGTERM and SIGKILL allows daemons to survive closing of a systemd logind session. I'd also appreciate if you could also consider unix.stackexchange.com/questions/484344/… and unix.stackexchange.com/a/490435/674
