卸载opencv
先进入在安装opencv时 cmake时候所在的目录(上面是直接在cmake文件夹下编译的，有时候会新建一个release文件夹)
sudo make uninstall
cd ..
sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv2 /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv_* /usr/local/lib/libopencv_*

疑难杂症解决方案

Project 'cv_bridge' specifies '/usr/include/opencv' as an include dir,
which is not found. It does neither exist as an absolute directory nor in
'/opt/ros/indigo//usr/include/opencv'
在/usr/include/下并没有opencv，建立了一个opencv文件夹，在github下下载了对应的indigo版本的 cv_bridge，是一个包（https://github.com/ros-perception/vision_opencv/tree/indigo），cv_bridge只是其中一部分，把cv_bridge这部分移动到新建立的opencv下即可，用到了 “sudo mv 路径1 路经2 (sudo mv cv_bridge /usr/include/opencv/) cv_bridge后面不能有斜杠”

ubuntu14.04升级后，登陆界面循环解决办法（Nvidia独立显卡）
https://blog.csdn.net/meirixuexi/article/details/72620864
解决办法：
a. sudo apt-get install build-essential pkg-config xserver-xorg-dev linux-headers-`uname -r` //编译依赖
b. sudo service lightdm stop //关闭lightdm
c. cd Downloads / && sudo sh NVIDIA-Linux-x86_64-361.28.run (一路默认，适用ubuntu16)
按提示重新安装一遍驱动后，问题完美解决；
