How to Remember and Restore Running Applications on Next Logon
|
||||
================================================================================
|
||||
You have made some apps running in your Ubuntu and don't want to stop the process, just managed your windows and opened your stuffs needed to work. Then, something else demands your attention or you have battery low in your machine and you have to shut down. No worries. You can have Ubuntu remember all your running applications and restore them the next time you log in.
|
||||
|
||||
Now, to make our Ubuntu remember the applications you have running in our current session and restore them the next time our log in, We will use the dconf-editor. This tool replaces the gconf-editor available in previous versions of Ubuntu but is not available by default. To install the dconf-editor, you need to run sudo apt-get install dconf-editor.
|
||||
|
||||
$ sudo apt-get install dconf-tools
|
||||
|
||||
Once the dconf-editor is installed, you can open dconf-editor from Application Menu. Or you can run it from terminal or run command (alt+f2):
|
||||
|
||||
$ dconf-editor
|
||||
|
||||
In the “dconf Editor” window, click the right arrow next to “org” in the left pane to expand that branch of the tree.
|
||||
|
||||
|
||||
|
||||
Under “org”, click the right arrow next to “gnome.”
|
||||
|
||||
|
||||
|
||||
Under “gnome,” click “gnome-session”. In the right pane, select the “auto-save-session” check box to turn on the option.
|
||||
|
||||
|
||||
|
||||
After you check or tick it, close the “Dconf Editor” by clicking the close button (X) in the upper-left corner of the window which is by default.
|
||||
|
||||
|
||||
|
||||
The next time you log out and log back in, all of your running applications will be restored.
|
||||
|
||||
Hurray, we have successfully configured our Ubuntu 14.04 LTS "Trusty" to remember automatically running applications from our last session.
|
||||
|
||||
Now, on this same tutorial, we'll gonna also learn **how to enable hibernation in our Ubuntu 14.04 LTS**:
|
||||
|
||||
Before getting started, press Ctrl+ALt+T on your keyboard to open the terminal. When it opens, run:
|
||||
|
||||
sudo pm-hibernate
|
||||
|
||||
After your computer turns off, switch it back on. Did your open applications re-open? If hibernate doesn’t work, check if your swap partition is at least as large as your available RAM.
|
||||
|
||||
You can check your Swap Area Partition Size from System Monitor, you can get it from the App Menu or run command in terminal.
|
||||
|
||||
$ gnome-system-monitor
|
||||
|
||||
### Enable Hibernate in System Tray Menu: ###
|
||||
|
||||
The indicator-session was updated to use logind instead of upower. Hibernate is disabled by default in both upower and logind.
|
||||
|
||||
To re-enable hibernate, run the commands below one by one to edit the config file:
|
||||
|
||||
sudo -i
|
||||
|
||||
cd /var/lib/polkit-1/localauthority/50-local.d/
|
||||
|
||||
gedit com.ubuntu.enable-hibernate.pkla
|
||||
|
||||
**Tips: if the config file does not work for you, try another one by changing /var/lib to /etc in the code.**
|
||||
|
||||
Copy and paste below lines into the file and save it.
|
||||
|
||||
[Re-enable hibernate by default in upower]
|
||||
Identity=unix-user:*
|
||||
Action=org.freedesktop.upower.hibernate
|
||||
ResultActive=yes
|
||||
|
||||
[Re-enable hibernate by default in logind]
|
||||
Identity=unix-user:*
|
||||
Action=org.freedesktop.login1.hibernate
|
||||
ResultActive=yes
|
||||
|
||||
Restart your computer and done.
|
||||
|
||||
### Hibernate your laptop when lid is closed: ###
|
||||
|
||||
1.Edit “/etc/systemd/logind.conf” via command:
|
||||
|
||||
$ sudo nano /etc/systemd/logind.conf
|
||||
|
||||
2. Change the line **#HandleLidSwitch=suspend to HandleLidSwitch=hibernate** and save the file.
|
||||
|
||||
3. Run command below or just restart your computer to apply changes:
|
||||
|
||||
$ sudo restart systemd-logind
|
||||
|
||||
That’s it. Enjoy! Now, we have both dconf and hibernation on :) Now, your Ubuntu will completely remember your opened apps and stuffs.

如何记住并在下一次登录时还原正在运行的应用
|
||||
================================================================================
|
||||
在你的 Ubuntu 里，你正运行着某些应用，但并不想停掉它们的进程，只想管理一下窗口，并打开那些工作需要的应用。接着，某些其他的事需要你转移注意力或你的机器电量低使得你必须马上关闭电脑。(幸运的是，)你可以让 Ubuntu 记住所有你正运行的应用并在你下一次登录时还原它们。
|
||||
|
||||
现在，为了让我们的 Ubuntu 记住当前会话中正运行的应用并在我们下一次登录时还原它们，我们将会使用到 `dconf-editor`。这个工具代替了前一个 Ubuntu 版本里安装的 `gconf-editor`，但默认情况下并没有在现在这个 Ubuntu 版本(注：这里指的是 Ubuntu 14.04 LTS) 里安装。为了安装 `dconf-editor`， 你需要运行 `sudo apt-get install dconf-editor`命令：
|
||||
|
||||
$ sudo apt-get install dconf-tools
|
||||
|
||||
一旦 `dconf-editor` 安装完毕，你就可以从应用菜单(注：这里指的是 Unity Dash)里打开它或者你可以通过直接在终端里或使用 `alt+f2` 运行下面的命令来启动它:
|
||||
|
||||
$ dconf-editor
|
||||
|
||||
在 “dconf Editor” 窗口中，在左边窗格里点击临近 "org" 的右箭头来展开这个选项的分支。
|
||||
|
||||
|
||||
|
||||
然后在 “org” 下，点击临近 “gnome” 的右箭头。
|
||||
|
||||
|
||||
|
||||
接着在 “gnome” 下点击 “gnome-session”。在右边窗格里，选择 “auto-save-session” 选项框并将它开启。
|
||||
|
||||
|
||||
|
||||
在你检查或对刚才的选项打钩之后，点击默认情况下位于窗口左上角的关闭按钮(X)来关闭 “Dconf Editor”。
|
||||
|
||||
|
||||
|
||||
在你登出并再登录回来时，所有你正运行的应用就可以被还原了。
|
||||
|
||||
欢呼吧，我们已经成功地配置了我们的 Ubuntu 14.04 LTS "Trusty" 来自动记住我们上一次会话中正在运行的应用。
|
||||
|
||||
现在，在这个教程里，我们也将学会 **如何在 Ubuntu 14.04 LTS 里开启休眠功能** :
|
||||
|
||||
在开始之前，在键盘上按 `Ctrl+Alt+T` 来开启终端。在它开启以后，运行：
|
||||
|
||||
sudo pm-hibernate
|
||||
|
||||
在你的电脑关闭后，再重新开启它。这时，你开启的应用被重新打开了吗？如果休眠功能没有发挥作用，请检查你的交换分区大小，它至少要和你可用 RAM 大小相当。
|
||||
|
||||
你可以在系统监视器里查看你的交换分区大小,而系统监视器可以通过在应用菜单或在终端里运行下面的命令来开启：
|
||||
|
||||
$ gnome-system-monitor
|
||||
|
||||
### 在系统托盘里启用休眠功能: ###
|
||||
|
||||
提示模块是通过使用 logind 而不是使用 upower 来更新的。默认情况下，在 upower 和 logind 中，休眠都被禁用了。
|
||||
|
||||
为了开启休眠功能，依次运行下面的命令来编辑配置文件：
|
||||
|
||||
sudo -i
|
||||
|
||||
cd /var/lib/polkit-1/localauthority/50-local.d/
|
||||
|
||||
gedit com.ubuntu.enable-hibernate.pkla
|
||||
|
||||
**提示：假如对你来说，这个配置文件并没有起到作用，请替换上面代码中的 /var/lib 为 /etc 来试试另一个配置文件**
|
||||
|
||||
复制并粘贴下面的代码到文件中并保存：
|
||||
|
||||
[Re-enable hibernate by default in upower]
|
||||
Identity=unix-user:*
|
||||
Action=org.freedesktop.upower.hibernate
|
||||
ResultActive=yes
|
||||
|
||||
[Re-enable hibernate by default in logind]
|
||||
Identity=unix-user:*
|
||||
Action=org.freedesktop.login1.hibernate
|
||||
ResultActive=yes
|
||||
|
||||
重启你的电脑就可以了。
|
||||
|
||||
### 当你盖上笔记本的后盖时，让它休眠: ###
|
||||
|
||||
1.通过下面的命令编辑文件 “/etc/systemd/logind.conf” :
|
||||
|
||||
$ sudo nano /etc/systemd/logind.conf
|
||||
|
||||
2. 将 **#HandleLidSwitch=suspend** 这一行改为 **HandleLidSwitch=hibernate** 并保存文件；
|
||||
|
||||
3. 运行下面的命令或重启你的电脑来应用更改:
|
||||
|
||||
$ sudo restart systemd-logind
|
||||
|
||||
就是这样。享受吧！现在我们有了 dconf 并开启了休眠功能 :) 你的 Ubuntu 将能够完全记住你开启的应用和窗口了。
