+Linux FAQs with Answers--How to enable and configure desktop sharing on Linux Mint Cinnamon desktop
+================================================================================
+> **Question**: I was trying to enable desktop sharing via Vino VNC server (vino-server) on Linux Mint 17 Cinnamon desktop. However, I notice that vino-preferences tool which allows us to configure vino-server (e.g., sharing option, security, notification on/off) no longer exists. Also, I cannot find desktop sharing menu on Cinnamon desktop. How can I configure desktop sharing via vino-server on the latest Linux Mint 17 Cinnamon desktop? 
+
+The latest Linux Mint Cinnamon desktop comes with vino-server pre-installed for VNC desktop sharing, but it's reported that desktop sharing configuration menu is missing.
+
+An alternative way to configure vino-server and enable desktop sharing is to use dconf-editor's graphical interface.
+
+First install dconf-editor:
+
+    $ sudo apt-get install dconf-editor
+
+Launch dconf-editor.
+
+    $ dconf-editor
+
+Navigate to "org->gnome->desktop->remote-access" on the left panel of dconf-editor. Then you will see various desktop sharing options.

+
+Most importantly, click on "enabled" to activate desktop remote access. Besides this, you can customize other options.
+
+For example, you can enable VNC password authentication by changing the following fields:
+
+- **authentication-methods**: set it to ['vnc']
+- **vnc-password**: change it to Base64-encoded string of a preferred password. 
+
+In this example, we choose VNC password as "password", and its Base64-encoded string is "cGFzc3dvcmQ=".
+
+Optionally, you can enable other options:
+
+- notify-on-connect: shows a desktop notification when vino-server receives a connection request.
+- prompt-enabled: a remote user is not allowed to access a desktop via VNC until the VNC request is approved by the desktop owner. 
+
+### Troubleshoot ###
+
+1. I am getting the following error when attempting to start vino-server.
+
+    ** (vino-server:4280): WARNING **: The desktop sharing service is not enabled, so it should not be run.
+
+To enable desktop sharing service, use dconf-editor as described above. Alternatively, run the following command.
+
+     # gsettings set org.gnome.Vino enabled true

+Linux常见问题与答案——如何检查我是否处于一个运行着的screen会话中
+================================================================================
+>**问题**：我经常使用screen命令来运行多个伪终端会话。好多次，我发现都记不得自己是否在一个screen会话中，还是在一个常规终端中。是否有一种简便的方法来检查我是否在一个运行着的screen会话中？
+
+一个快捷而又简单的方法来检查你是否处于一个screen伪终端中，还是在一个常规终端中，就是检查STY环境变量。当调用了screen，就会把STY变量值设置为会话名。因此，如果STY环境变量被设置为任何非空字符串，就意味着你正处于一个screen会话中。
+
+     $ echo $STY 
+
+> 2858.pts-3.my_host
+
+然而，请注意，上面的方法**只有当**你是在本地计算机上运行screen命令的时候。如果你从本地计算机的screen会话中SSH到任何远程计算机上，远程计算机上的STY变量不会被设置，尽管在技术上看，你仍然处于一个screen会话中。
+
+事实上，一个更为可靠的检查你是否处于一个screen会话中的方法，是按“Ctrl-a”+“Ctrl-t”。如果你处于screen会话中，终端会在底部显示时间信息。
