Ubuntu 14.04 无法显示系统监视器的网络速度
我发现网络监视器的速度值在系统监视器升级后不能正常显示到Ubuntu 14.04。包括indicator-multiload和dstat
示例 1：
我可以467KB/Sec在firefox Downloads 中看到下载速度，但在Network History 中没有任何显示（零）
示例 2：
下图中，git下载速度为358KB/Sec，但是in的接收/发送值dstat仍然为0。 并且没有显示indicator-multiload
我可以理解，网络速度监视器以某种方式被禁用。我怎样才能做到正确？

正如@Aditya 和@Bryan建议的，这是内核中的错误，可以通过更新内核来修复。
\n\n例如：\n我的系统是Ubuntu 14.04. 内核版本为3.13.0，系统版本为64bit (amd64)。
它们都可以通过以下命令获取：
\n\n\xe2\x94\x8c\xe2\x94\x80 (marslo@MarsloJiao ~) ->\n\xe2\x94\x94\xe2\x94\x80 $ uname -r\n3.13.0-30-generic\n或者
\n\n\xe2\x94\x8c\xe2\x94\x80 (marslo@MarsloJiao ~) ->\n\xe2\x94\x94\xe2\x94\x80 $ dpkg -l | grep "linux\\-[a-z]*\\-"\nii linux-headers-3.13.0-24 3.13.0-24.47 all Header files related to Linux kernel version 3.13.0 \nii linux-headers-3.13.0-24-generic 3.13.0-24.47 amd64 Linux kernel headers for version 3.13.0 on 64 bit x86 SMP \nii linux-headers-3.13.0-30 3.13.0-30.55 all Header files related to Linux kernel version 3.13.0\nii linux-headers-3.13.0-30-generic 3.13.0-30.55 amd64 Linux kernel headers for version 3.13.0 on 64 bit x86 SMP\nii linux-headers-generic 3.13.0.30.36 amd64 Generic Linux kernel headers\nii linux-image-3.13.0-24-generic 3.13.0-24.47 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP\nii linux-image-3.13.0-30-generic 3.13.0-30.55 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP\nii linux-image-extra-3.13.0-24-generic 3.13.0-24.47 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP\nii linux-image-extra-3.13.0-30-generic 3.13.0-30.55 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP\nii linux-image-generic 3.13.0.30.36 amd64 Generic Linux kernel image\nii linux-libc-dev:amd64 3.13.0-30.55 amd64 Linux Kernel Headers for development\nii linux-sound-base 1.0.25+dfsg-0ubuntu4 all base package for ALSA and OSS sound systems\n\n\n
因此，以下步骤可以解决该问题：
\n\n- \n
首先需要从/~kernel-ppa/mainline/v3.14.1-trusty下载三个deb包：
\n\n- \n
- linux-headers-.*_amd64.deb ( linux-headers-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb ) \n
- linux-headers-.*all.deb ( linux-headers-3.14.1-031401_3.14.1-031401.201404141220_all.deb ) \n
- linux-image-.*amd64.deb ( linux-image-3.14.1-031401-generic_3.14.1-031401.201404141220_amd64.deb ) \n
\n安装所有这些 deb
\n\n- \n
$ sudo dpkg -i *.deb\n
\n重新启动您的系统
\n\n- \n
$ sudo reboot\n
\n
\n\n
答对了！网络速度回系统监控！！\n
