启动 Ubuntu 系统后恢复以前的应用程序状态

  • 772

以前，我曾经sudo shutdown -h now关闭过 macOS。在此之后开机，系统会将所有应用程序（如 Chrome、VS Code、PDF）恢复到关机前的状态。

现在，我使用相同的命令sudo shutdown -h now关闭 Ubuntu。但是，开机后，系统会启动一个全新的状态，而不会将应用程序恢复到关机前的状态。

macOS 使用了什么功能？我也可以在 Ubuntu 上使用它吗？

gnome shutdown session macosx

    它被称为“会话管理”

    我可以在ubuntu上使用它吗？

    不在默认桌面中

    但是您可以为此使用Linux 窗口会话管理器或gnome 的Gnome Window 会话管理器扩展。您将在 Gnome Shell 顶部栏上获得一个指示器，您可以在其中保存和恢复会话。从第二个链接安装（第一个有类似的设置）：

    设置

    • 确保您已安装 nodejs（例如，执行 node -v 如果没有输出，请安装它）。

    • 通过 npm 安装 lwsm：（npm install -g linux-window-session-manager在某些系统上您可能想要使用 sudo）

    • 下载或克隆存储库并将所有文件移动到/home/your-user-name/.local/share/gnome-shell/extensions/[email protected]

    • 在某些情况下——尤其是当你使用 nvm 时，你可能需要配置你的 lwsm 安装路径（你可以在成功安装后通过哪个 lwsm 找到）扩展通过gnome-shell-extension-prefs.

    设置完成后安装：

    cd tmp
git clone [email protected]:johannesjo/gnome-shell-extension-window-session-manager.git
mv gnome-shell-extension-window-session-manager ~/.local/share/gnome-shell/extensions/[email protected]

  2. 它没有关闭，无论如何看一下以下命令：

    pm-action - 暂停或休眠您的计算机

    pm-hibernate [--help]
pm-suspend [--quirk-*] [--help]
pm-suspend-hybrid [--quirk-*] [--help]

    从手册页：

    These commands can be used to put the machine in a sleep state. The precise way how this
   is done can be influenced by installing executables and configuration snippets. For some
   options external programs are needed.

   These commands will usually be called by UPower or hald when triggered to do so by a
   program in a desktop session such as gnome-power-manager. Calling them from the command
   line is also possible, but it is not guaranteed that all programs in your desktop session
   keep working as expected.

   pm-suspend
       During suspend most devices are shutdown, and system state is saved in RAM. The system
       still requires power in this state. Most modern systems require 3 to 5 seconds to
       enter and leave suspend, and most laptops can stay in suspend mode for 1 to 3 days
       before exhausting their battery.

   pm-hibernate
       During hibernate the system is fully powered off, and system state is saved to disk.
       The system does not require power, and can stay in hibernate mode indefinitely. Most
       modern systems require 15 to 45 seconds to enter and leave hibernate, and entering and
       leaving hibernate takes longer when you have more memory.

   pm-suspend-hybrid
       Hybrid-suspend is the process where the system does everything it needs to hibernate,
       but suspends instead of shutting down. This means that your computer can wake up
       quicker than for normal hibernation if you do not run out of power, and you can resume
       even if you run out of power. s2both(8) is an hybrid-suspend implementation.
