Let scim and ibus support Skype

Update 28/4/2012 - If you're using Ubuntu 12.04 Precise Pangolin, install ibus-qt4 first.
sudo apt-get install ibus-qt4

By default, I cannot input Chinese in Linux version of Skype. This issue doesn't get solved when Karmic Koala decided to introduce a new input framework, ibus, to replace scim.

To solve this problem, add these 3 lines into your .bashrc file and reboot:

 export GTK_IM_MODULE=ibus  
 export XMODIFIERS=@im=ibus  
 export QT_IM_MODULE=ibus  

If you prefer scim, maybe these lines will help (not tested):

 export XMODIFIERS=@im=SCIM  
 export GTK_IM_MODULE=scim  
 export QT_IM_MODULE=scim  

Skype is better now under Ubuntu.
