在Terminal中运行dde-control-center会出现这样的错误: This application failed to start because it could not find or load the Qt platform plugin "xcb". 参考:http://blog.csdn.net/windows_nt/article/details/24205671 将/usr/lib/i386-linux-gnu/的下列文件拷贝到/usr/bin/中 libQt5Widgets.so.5 libQt5Gui.so.5 libQt5Core.so.5 libicui18n.so.51 libicuuc.so.51 libicudata.so.51 libQt5DBus.so.5 然后重启就可以了
