I'm developing a c++ project on ubuntu 13.10. To compile this project i need OpenCV and Armadillo libraries. After the OpenCV installation (ver. 2.4.6) Ubuntu doesn't run. During the boot appears a frozed-black screen with the X-shaped mouse pointer. How can i resolve this problem?The same thing happens with wubi (Ubuntu 13.10 on Windows), doesn't work after OpenCV installation. Thanks
