---------
Ubuntu 17.10 Artful Aardvark is just released. A big change in this release is that it ditches Unity for Gnome. Most likely this will be part of the next LTS version “18.04”.

Here is the instructions how to setup Chinese input method in Ubuntu Artful.

1. First, go to “Language Support”, make sure the “Chinese(simplified)” or “Chinese Traditional”(or both) is installed completely.

2. Go to “Input Method”, make sure you select “ibus” as the selected user configuration. An user logout may be required.

3. Go to “Settings -> Region & Language”, in the “Input Sources” section, add the “Chinese(Pinyin)” input method.

Now you should be able to see the input method icon “en/拼” on the top left corner of the desktop. Use “Super + Space” to switch the input method as normal.

※ notice fcitx users
If you are use Fcitx input method in previous, it will still remian process after upgrade but keyboard sequence will not work. Becase iBus is default settting for 17.10 Artful Aardvark.

So, use one of following 3 method.

1. change OS's defult iBus input method to Fcitx which is your old default method.

2. use iBus input method and remove Fcitx
 > explicitly set to iBus in 'keyboard and language' setting, 17.10 will automatically remove fcitx process
   (it maybe different your situation)
