在电源管理中启用休眠？

Question

我有一台带有最新版本Linux的笔记本电脑。我设置了一个交换分区，并正常运行pm-hibernate (启动时关闭并继续运行)。然而，在电源管理设置“当电池非常低”冬眠不是一种选择。

我查看了Python程序(/usr/share/cinnamon/cinnamon-settings/modules/cs_power.py)，似乎有一段代码可以检查是否可能冬眠：

def get_available_options(up_client):
    can_suspend = False
    can_hibernate = False
    can_hybrid_sleep = False

    # Try logind first
    try:
        connection = Gio.bus_get_sync(Gio.BusType.SYSTEM, None)
        proxy = Gio.DBusProxy.new_sync(
            connection,
            Gio.DBusProxyFlags.NONE,
            None,
            "org.freedesktop.login1",
            "/org/freedesktop/login1",
            "org.freedesktop.login1.Manager",
            None)

        can_suspend = proxy.CanSuspend() == "yes"
        can_hibernate = proxy.CanHibernate() == "yes"
        can_hybrid_sleep = proxy.CanHybridSleep() == "yes"
    except:
        pass

    # Next try ConsoleKit
    try:
        connection = Gio.bus_get_sync(Gio.BusType.SYSTEM, None)
        proxy = Gio.DBusProxy.new_sync(
            connection,
            Gio.DBusProxyFlags.NONE,
            None,
            "org.freedesktop.ConsoleKit",
            "/org/freedesktop/ConsoleKit/Manager",
            "org.freedesktop.ConsoleKit.Manager",
            None)

        can_suspend = can_suspend or (proxy.CanSuspend() == "yes")
        can_hibernate = can_hibernate or (proxy.CanHybridSleep() == "yes")
        can_hybrid_sleep = can_hybrid_sleep or (proxy.CanHybridSleep() == "yes")
    except:
        pass

    def remove(options, item):
        for option in options:
            if option[0] == item:
                options.remove(option)
                break

    lid_options = [
        ("suspend", _("Suspend")),
        ("shutdown", _("Shutdown immediately")),
        ("hibernate", _("Hibernate")),
        ("blank", _("Lock Screen")),
        ("nothing", _("Do nothing"))
    ]

    button_power_options = [
        ("blank", _("Lock Screen")),
        ("suspend", _("Suspend")),
        ("shutdown", _("Shutdown immediately")),
        ("hibernate", _("Hibernate")),
        ("interactive", _("Ask")),
        ("nothing", _("Do nothing"))
    ]

    critical_options = [
        ("shutdown", _("Shutdown immediately")),
        ("hibernate", _("Hibernate")),
        ("nothing", _("Do nothing"))
    ]

    if not can_suspend:
        for options in lid_options, button_power_options, critical_options:
            remove(options, "suspend")

    if not can_hibernate:
        for options in lid_options, button_power_options, critical_options:
            remove(options, "hibernate")

    return lid_options, button_power_options, critical_options, can_suspend, can_hybrid_sleep

如果在这段代码之后将can_hibernate设置为True，则会出现该选项，但它不起作用。当电池电量不足时，我如何将其设置为hibernate？

我刚刚处理了在LinuxMint19.3肉桂设置上启用休眠的问题。

( A)我第一次学习这门课，https://www.reddit.com/r/linuxmint/comments/93ta9u/enable_冬眠_在……里面_linux_薄荷_19_塔拉/

注意:请确保您有足够大的交换分区。1.)在"/etc/polkit-1/localauthority/50-local.d“中创建名为"com.ubuntu.enable-hibernate.pkla”的文件：sudo touch /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla 2)。用您最喜欢的编辑器打开这个文件(在根特权下)，并将这些行粘贴到其中并保存它：默认情况下重新启用hibernate Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes 默认情况下，在logind中重新启用hibernate. Identity=unix-user:* Action=org.freedesktop.login1.hibernate ResultActive=yes 3。在文件"/etc/default/grub“中编辑这一行，这样看起来如下所示：GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=swap_partition_uuid" swap_partition_uuid -您可以在文件"/etc/fstab”中找到这个UUID，所以用交换分区4的实际uuid替换该字符串。通过执行以下命令更新grub配置：sudo update-grub

• 它使hibernation可以使用systemctl hibernate命令。
• 但是hibernate按钮没有显示在断电窗口中，hibernate选项也没有显示在电源管理设置中(这是您似乎感兴趣的；)

( B)然后，我创建了/var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla文件，如本教程http://linuxg.net/how-to-enable-hibernation-and-add-the-hibernate-button-to-the-shutdown-menu-on-ubuntu-14-04-trusty-tahr/所述。

为了更清晰起见，我编辑了引文的一些部分。

1.)在"/var/lib/polkit-1/localauthority/50-local.d“中创建名为"com.ubuntu.enable-hibernate.pkla”的文件：sudo touch /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla 2)。用您最喜欢的编辑器打开这个文件(在root特权下)，并将这些行粘贴到其中并保存它：默认情况下，在upower中重新启用hibernate Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes 默认情况下，在logind中重新启用hibernate. Identity=unix-user:* Action=org.freedesktop.login1.hibernate ResultActive=yes

• Hibernate按钮和选项现在可以在我的设置！

希望这能有所帮助。

你可能会发现我的小向导很有用！我在冬眠中挣扎了一段时间。
