比如在火狐的内容里面用SCIM打字，你就发现，那个输入法的方框从前面拖动到你输入字符的位置，每次都这样，当然卡的很！你再看看opera用SCIM，它的那个方框就聪明点，保持在上面不动，就没有那么卡拉！所以只要改变一下火狐用SCIM打字的方框，就不卡拉！
你可以在 libreoffice里面打字，看看，是不是每次输入法都能找到你想要输入字符的位置，要是SCIM在火狐里面也这样，就没有那么卡拉！


不明白，始终都是scim配ff,不论是debian,gentoo还是freebsd都没出过问题

不明白你说的什么意思，我一直用scim，没有任何问题。
怀疑是配置问题，以下是slackware自带的scim配置脚本/etc/profile.d/scim.sh，可以试下。
#!/bin/sh
# SCIM (Smart Common Input Method platform). This is used to support the
# entering of text in non-US-English languages.
# For SCIM to work, you need to use a UTF-8 locale. Make sure it ends on
# ".UTF-8", not "utf-8"! As an example, you would need to use en_US.UTF-8
# for a US locale (export LANG=en_US.UTF-8), not en_US.
#
# The locale (LANG variable) is set in /etc/profile.d/lang.sh.
if [ -x /usr/bin/scim ]; then
# Enable legacy X applications to use scim:
export XMODIFIERS="@im=SCIM"
## Enable Qt/KDE applications to use scim (not working with kde4):
#export QT_IM_MODULE="scim"
# Make scim start automatically if the "magic key" Ctrl-Space is pressed:
export XIM_PROGRAM="/usr/bin/scim -d"
fi
if [ -x /usr/bin/scim-bridge ]; then
# Let GTK applications like Firefox/Thunderbird use scim-bridge as
# default immodule:
export GTK_IM_MODULE="scim-bridge"
# Enable Qt4/KDE4 applications to use scim:
export QT_IM_MODULE="scim-bridge"
fi
# This ensures scim starts when you logon.
# This will only work if you login through runlevel 4 (graphical login)!!!
# Better is to have it start through Ctrl-Space like configured higher up ^^.
#if [ ! `ls /tmp/scim-socket*` ]; then
# /usr/bin/scim -d
#fi
# GTK+ environments such as XFce should support SCIM automatically, BUT
# if the first app you run is a Qt one, you'll run into problems. This
# can be avoided by going into Menu -> Settings -> Autostarted Applications
# and adding SCIM: /usr/bin/scim -d
# KDE will not start SCIM automatically, so you will need a script such as
# this one in your /root/.kde/Autostart:
#!/bin/bash
#if [ -x /usr/bin/scim ]; then
# /usr/bin/scim -d &
#fi
# Obviously, uncomment all but the first line. :-)


他在说，opera的时候没有光标跟随功能吧....
