假设ubuntu安装的64位的，在当中安装32位软件时就会碰到缺失libgtk-x11-2.0.so的情况
比方用wine安装qq时 启动qq时就会报这种错误
error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
网上的解决方法
sudo apt-get install ia32-libs ia32-libs-gtk
可是又出现一下错误提示：
sudo apt-get install ia32-libs
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package ‘ia32-libs’ has no installation candidate
于是又搜索，知道要加入曾经版本号的源，然后即可了
以下是加入源的方法：
方法1：
sudo gedit /etc/apt/sources.list
然后在最后加入上： deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse
方法2：
终端中输入：
echo "deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >> sudo gedit /etc/apt/sources.list
还有其它加入本地源的方法。能够參考：http://hi.baidu.com/android4/item/6c0f962351a7ec102b0f1cac
加入完源之后
sudo apt-get update
sudo apt-get install ia32-libs ia32-libs-gtk
这样就应该能够了
常遇到QQ图标不能点击，运行以下脚本重新启动后可修复：
ps -ef | grep tm2013 | awk '{print $2}' | xargs kill -9
nohup tm2013 >/dev/null 2>&1 &
