Install the little penguin Input Method in ubuntu. My friends said that the little penguin Input Method in Linux is good. In addition, I really feel that the built-in input method is not very easy to use. I still like sogou's style. Below I will record my installation and usage steps. 1. Run the command on the terminal: sudo apt-get install fcitx 2. When the Chinese language environment is installed on ubuntu, scim input method is automatically installed, but this scim is not only large, it is also compatible with many programs (firefox, eva, etc. In comparison, I think fcitx is a little penguin. The following method allows scim and fcitx to coexist. $ Sudo apt-get install im-switch libapt-pkg-perl fcitx 3. After installation, run the following command to make the system default fcitx as the default input method. Note that do not add sudo before. It is best to restart X to make the settings take effect. $ Im-switch-s fcitx
