scim输入法为什么只能在网页中用？

mind5

我的输入法也无法自动加载，而且在终端中输入scim后，只能在网页上使用输入法，其他地方无法输入中文。
输入locale时：------------------------------------------------------
LANG=zh_CN.GB18030
LC_CTYPE="zh_CN.GB18030"
LC_NUMERIC="zh_CN.GB18030"
LC_TIME="zh_CN.GB18030"
LC_COLLATE="zh_CN.GB18030"
LC_MONETARY="zh_CN.GB18030"
LC_MESSAGES="zh_CN.GB18030"
LC_PAPER="zh_CN.GB18030"
LC_NAME="zh_CN.GB18030"
LC_ADDRESS="zh_CN.GB18030"
LC_TELEPHONE="zh_CN.GB18030"
LC_MEASUREMENT="zh_CN.GB18030"
LC_IDENTIFICATION="zh_CN.GB18030"
LC_ALL=
输入scim时：------------------------------------------------------
