Here's the exact sequence of operations needed to reproduce the bug: STEP 1: /usr/lib/nux/unity_support_test -p
STEP 2: sudo apt-get install libopencv-dev STEP 3: /usr/lib/nux/unity_support_test -p Alternatively, STEP 1: Write a simple OpenGL program to print GL_VERSION string. STEP 2: Install opencv developer package: sudo apt-get install libopencv-dev (It seems that during installation opencv adds Nvidia drivers to the kernel.) STEP 3: Run the OpenGL program again and check the OpenGL version. ** Description changed: I'm using Thinkpad Edge 430 equipped with 3rd generation Intel Ivybridge Graphics Card running Ubuntu 13.10. SDL reports OpenGL 3.0 Mesa 9.2.1. - After installing OpenCV (sudo apt-get install opencv), SDL reports - OpenGL 1.4 Mesa 9.2.1 + After installing OpenCV (sudo apt-get install libopencv-dev), SDL + reports OpenGL 1.4 Mesa 9.2.1 Because of downgraded opengl context all opengl applications throw "Major opcode of failed request: 153 (GLX)" error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1251522 Title: OpenCV downgrades Intel Ivybridge Graphics Card drivers on Ubuntu 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/opencv/+bug/1251522/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
