+# Prevent logoff from killing tmux sessions
+
+Lately I've noticed that logging out of i3, intentionally or when i3 fails, would also kill any tmux or emacs sessions.
+This is extremely annoying.
+
+This is caused by a new default in logind (systemd's login) to kill user process on logoff.
+You can revert this setting in your logind.conf (`/etc/systemd/logind.conf`):
+
+```cfg
+KillUserProcesses=no
+```
+
+Or only for a specific process (e.g., tmux):
+
+```shell
+systemd-run --scope --user tmux
+```
