升级了SCIM.采用以下方法
我们先可以安装输入法：你可以选择安装 fcitx 还是 安装SCIM
* SCIM:
$sudo apt-get install scim scim-gtk2-immodule scim-modules-socket scim-modules-table scim-pinyin scim-tables-zh scim-input-pad
$sudo sh -c " echo 'export XMODIFIERS=@im=SCIM ; export GTK_IM_MODULE="scim" ; scim -d ' > /etc/X11/Xsession.d/95xinput "
$sudo chmod 755 /etc/X11/Xsession.d/95xinput
* fcitx:
$sudo apt-get install fcitx
$sudo sh -c " echo 'export XMODIFIERS=@im=fcitx ; export GTK_IM_MODULE="fcitx" ; fcitx ' > /etc/X11/Xsession.d/95xinput "
$sudo chmod 755 /etc/X11/Xsession.d/95xinput
重新启动Xwindow完成。按 Ctrl + 空格 键激活输入法。
