Package: tmux Version: 3.3a-1 Severity: normal Under some starting conditions (eg. "starting from an xterm in Gnome"), the tmux server gets killed when the user logs off (or, more practically, gets logged off by the X server crashing). This damages one of tmux's strong points: keeping whatever is launched in it running no matter how unstable the terminal connection is.
Steps to reproduce: * In a fresh sid installation, start Gnome under X11 (Wayland not tested). * Alt+F2, xterm * tmux * Ensure you recognize the screen again later on * Log out * Log in back again, open xterm again * tmux attach: "no sessions" -- the session was killed Note that this is sentitive to the precise way tmux is being launched; for example, if gnome-terminal were used, things would behave as normal. That indicates that there is something processes can do to protect themselves from getting killed (possibly with cgroups involved). I've originally reported this against systemd as https://bugs.debian.org/946645 assuming it's an error in `KillUserProcesses=no` (whose default has caused similar grief), but maintainers there insist it's not about that. The issue and discussion around it may have valuable material, also w/rt other things I've tested. Please enable tmux to persist in the rough desktop environment. If you think that it's not tmux's fault but tmux sessions should still persist, please reassign to where you think this should be fixed. Thanks chrysn PS. The issue appears to also exist in 3.4, which I've tested for unrelated reasons. -- System Information: Debian Release: bookworm/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.18.0-3-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages tmux depends on: ii libc6 2.33-8 ii libevent-core-2.1-7 2.1.12-stable-5+b1 ii libtinfo6 6.3+20220423-2 ii libutempter0 1.2.1-2 tmux recommends no packages. tmux suggests no packages. -- no debconf information -- To use raw power is to make yourself infinitely vulnerable to greater powers. -- Bene Gesserit axiom
