Comment 14 for bug 80444

I have the same problem.
If I run kcontorl/kcmshell with "sudo" , it's just ok:
roy@roy-laptop:/etc/xdg/menus/kde-applications-merged$ sudo kcmshell --list
X Error: BadDevice, invalid or uninitialized input device 169
  Major opcode: 148
  Minor opcode: 3
  Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 169
  Major opcode: 148
  Minor opcode: 3
  Resource id: 0x0
Failed to open device
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

kdeinit: Can't connect to the X Server.
kdeinit: Might not terminate at end of session.
下列模块可用：
kcmcgi - 配置 CGI KIO 仆人
cookies - 配置 cookies 相关设置
khtml_java_js - 配置 Java 和 JavaScript 的行为
khtml_behavior - 配置浏览器行为
kcmhistory - 配置任务侧边栏
khtml_fonts - 配置网页所使用的字体
khtml_filter - 配置 Konqueror 的广告拦截过滤器
khtml_plugins - 配置浏览器插件
kcmcss - 配置用来渲染网页的样式表
……

but, if I run kcmshell without "sudo", it can't find obex modules:
X Error: BadDevice, invalid or uninitialized input device 169
  Major opcode: 148
  Minor opcode: 3
  Resource id: 0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 169
