无法使用 loginctl 终止用户会话

  • 772

我正在使用 sddm 作为显示管理器运行 lubuntu 20.04。

每当我通过 gui 注销并以其他用户身份登录时，用户会话都不会被杀死（不知道它是否是设计使然）。所以 loginctl 为我的用户显示了双重会话。

我杀死的 2. 用户的所有会话

killall -u second_user_name

对于我的主要用户 3 个会话仍然存在。

我可以删除的具有最低会话 ID 的会话

sudo loginctl kill-session 3

剩饭剩菜

loginctl list-sessions 
SESSION  UID USER SEAT  TTY
     11 1000 alex seat0    
     21 1000 alex seat0

下次试试

alex@Guilmon:~$ sudo loginctl kill-session 11
[sudo] Passwort für alex: 

alex@Guilmon:~$ loginctl list-sessions 
SESSION  UID USER SEAT  TTY
     11 1000 alex seat0    
     21 1000 alex seat0    

2 sessions listed.
alex@Guilmon:~$ 


How can I get rid of it? Or avoid this situation (more than one session per user)
lubuntu

    我想我发现要避免这种情况。在

    /etc/systemd/logind.conf

KillUserProcesses=yes

    从手册页

    KillUserProcesses=
           Takes a boolean argument. Configures whether the processes of a user should be killed when the user logs out. If true, the scope unit
           corresponding to the session and all processes inside that scope will be terminated. If false, the scope is "abandoned", see
           systemd.scope(5), and processes are not killed. Defaults to "no", but see the options KillOnlyUsers= and KillExcludeUsers= below.

           In addition to session processes, user process may run under the user manager unit [email protected]. Depending on the linger settings, this may
           allow users to run processes independent of their login sessions. See the description of enable-linger in loginctl(1).

           Note that setting KillUserProcesses=yes will break tools like screen(1) and tmux(1), unless they are moved out of the session scope. See
           example in systemd-run(1).

    I restart 

        sudo systemctl restart systemd-logind.service

    注销后 1. 用户并登录 2. 用户并返回

    alex@Guilmon:~$ loginctl 
SESSION  UID USER SEAT  TTY
     15 1000 alex seat0    

1 sessions listed.
alex@Guilmon:~$

    不再等待在关闭或重新启动期间从废弃的用户会话中停止某些东西。
