In order to do so, please install "gdb" then run your test again (without "systemd.legacy_systemd_cgroup_controller") but before logging out from the session which has screen please start gdb as root in another terminal and do: $ gdb -p 1 $ b scope_notify_cgroup_empty_event $ c Get back to the other terminal and log out. Gdb should stop at the breakpoint. If so please run the command "bt" in gdb and show the output. Before quitting gdb, show the content of the follwoing files (you'll need another terminal): /sys/fs/cgroup/unified/user.slice/user-<X>.slice/session-<Y>.scope/cgroup.events /sys/fs/cgroup/unified/user.slice/user-<X>.slice/session-<Y>.scope/cgroup.procs where: X is the uid of the user that started screen Y is the session number where screen was started from You can then quit gdb by entering "q" in gdb.
