Install Scim

I need to use Chinese input, so I followed this guide

sudo fontconfig-voodoo -f -s zh_CN

sudo apt-get install im-switch libapt-pkg-perl
sudo apt-get install scim-pinyin #this part is missing in the guide
sudo im-switch -s scim -z default

And the guide recommends scim-bridge, because scim will crash
Realplayer, Openoffice, Acrobat Reader, etc. But scim-bridge
won't work for me. So to prevent Realplayer from crashing,
I did the following:

Edit /usr/bin/realplay, add this line after #!/bin/bash

GTK_IM_MODULE=xim;export GTK_IM_MODULE

I suspect it's the same for Acrobat Reader and Open office, but since I am not using them right now, it's still remain to be tested.
