    dtk动了什么操作吗？自己编译了什么  之前有没有出现 还是操作了什么出现的

    小白用户，基本就是下载商店应用，不懂dtk

    我觉得从网络配置方面看吧，我这网络配置，在控制面板里面的网络里也没法配置

    用 gdb 调试一下（这属于人力 profile）：

    执行：
    sudo apt install deepin-system-monitor-dbgsym
    gdb deepin-system-monitor

    这就进入了调试模式，输出：

    done.
    (gdb)

    输入 'run' 回车，开始运行 deepin-system-monitor：

    Starting program: /usr/bin/deepin-system-monitor

    如果再次出现了 CPU 占用 100% ，在 gdb 里面按 ctrl+C 使其暂停，然后输入 ‘backtrace’，得到类似这样的调用栈：

    #0  0x00007f2cebe7363d in poll () at ../sysdeps/unix/syscall-template.S:84
    #1  0x00007f2ce92b0a56 in  () at /lib/x86_64-linux-gnu/libglib-2.0.so.0
    #2  0x00007f2ce92b0b5c in g_main_context_iteration () at /lib/x86_64-linux-gnu/libglib-2.0.so.0

    #6  0x0000563abeb692d5 in main(int, char**) (argc=, argv=) at src/main.cpp:78

    把这段复制保存到一个文本文件里。再输入 'run' 恢复执行，几秒后重复 ctrl+C - backtrace - run 的循环，看看调用栈有什么规律吗？把 backtrace 的结果贴出来看看。

    这个共同的调用栈是在程序的初始化阶段，仅执行一次。看起来应该是 StatusMonitor::updateStatus() 执行得非常慢，而不是真的卡住。
    至于具体原因还无法确定，可能是进程数太多（会多到这个程度吗？用 sudo ps -aux | wc -l 统计一下），也可能是 Qt 有 bug（装过非deepin提供的Qt吗？），或者就是深度监视器自己的bug。

    这个问题应该是与特定的环境有关（安装了什么程序，运行了什么程序），从外部还真不太好定位。楼主懂C/C++编程吗？如果懂可以下载源码来进一步调试：https://github.com/manateelazycat/deepin-system-monitor/

    另一条途径是做减法，关掉系统里可以关掉的程序（尤其是自行安装的），看是哪个程序触发的。你可以先 sudo ps -aux 显示一下现在的所有进程。

    这个问题，咳咳，就让它随缘吧

    为什么不是这里出的错？

    1. ERROR: opening handler for device teredo: 不允许的操作
    2. ERROR: opening handler for device enp2s0: 不允许的操作
    Copy the Code


    我觉得是无法读取网络的问题

    我也不是啥专业的测试人员，自己能用就忍了吧，工作比较忙。
    而且有个啥bug的不是很正常嘛，有人这么劝过我，Linux能用就行了，别瞎折腾。我觉得挺对的，毕竟是工作机。

    再一个，现在的deepin我是比较满意的，内存方面控制的很好，些许问题，只要不在我眼前我就当不存在好了……
    毕竟我刚刚官网升级都失败了，只能重装……再折腾崩系统，又是好几天，心累
