在正常情况下删除 chromium的时候，却不可能干净删除。会弹出
To fully uninstall it, run '/opt/cxchromium/bin/cxuninstall' as root.
这个时候，我们应该做的是
If you installed it using the .deb package (which is what we offer for Ubuntu users), your best bet is to use the Synaptic package manager (look under the Administration tools) to remove it. A command line way to do that is this:
sudo aptitude purge cxchromium
这样，就可以完全干净的删除了。
