XUbuntu 18.10 light-locker错误行为

使用 XUbuntu 18.10（全新安装）锁定系统时，显示器会立即暂停；按任何键或鼠标按钮都无法唤醒它。CTRL + ALT + F7最后按 唤醒显示器，并显示以下消息：

This session is locked You'll be redirected to the unlock dialog automatically in a few seconds

在此处输入图片描述

然后出现锁定屏幕，一切都按预期进行。

另一个解决方案是输入密码（当显示器仍然空白时），然后按 ENTER，这样就可以唤醒显示器并解锁会话（当然，如果密码输入正确的话）。

我有这些设置（显示电源管理 on或off和/或自动锁定会话激活与否没有区别):

在此处输入图片描述 在此处输入图片描述

预期行为显示电源管理 on和自动锁定会话激活的是：

  1. 当首次锁定系统时，显示器应该仍然处于打开状态
  2. 应显示锁定窗口
  3. 10 分钟后显示器应该变黑
  4. 15 分钟后，显示器将进入睡眠状态
  5. 60 分钟后，显示器应关闭
  6. 当按下任何键或鼠标时，显示器应打开并显示锁定窗口

我应该怎么做才能获得所需的行为？我也不想通过使用 xscreensaver 来避免这个问题

更新

无论我选择什么，行为都是相同的显示电源管理和/或自动锁定会话。

和电源管理器未登记会话和启动（屏幕锁仍然检查）行为是一样的。我猜这是一个屏幕锁（灯柜） 问题。

这是/var/log/syslog锁定时创建的：

答案1

我还没有真正解决您的问题，但有一个临时解决方案。

我在这里找到了一种无需重启机器/LightDM 即可恢复的方法。

在您的 tty1 ++Ctrl中，以 root 身份输入，其中是您通过运行获得的会话 ID 。AltF1loginctl unlock-session [id][id]loginctl list-sessions

如果第一个 ID 不起作用，请尝试使用用户帐户的其他会话 ID。

也尝试一下这个。

sudo service lightdm restart

答案2

还有一些人报告了类似的问题。请看： https://github.com/the-cavalry/light-locker/issues/138

一个（临时）解决方案是：

更改脚本：/usr/bin/xflock4

将“light-locker-command -l”行替换为“dm-tool switch-to-greeter”

总共：

    for lock_cmd in \
      "xfce4-screensaver-command -l" \
      "xscreensaver-command -lock" \
      "light-locker-command -l" \
      "gnome-screensaver-command --lock" 
    do
      $lock_cmd >/dev/null 2>&1 && exit 
    done

这将变成：

    for lock_cmd in \
      "xfce4-screensaver-command -l" \
      "xscreensaver-command -lock" \
      "dm-tool switch-to-greeter" \
      "gnome-screensaver-command --lock"
    do
      $lock_cmd >/dev/null 2>&1 && exit
    done
