I have the solution for this bug ! 1):
- In fact, the nvidia-331 driver erase the intel's driver configuration's files, that's the cause of "GLX extension missing on screen 0" and the unity's bug. 2) - So we need to install nvidia-prime and nvidia-331. Don't log out !!!! 3) - run terminal and execute : "sudo apt-get install --reinstall libgl1-mesa-glx" this commande reinstall the configuration of intel's HD4000 driver. 4) - Then reboot your computer - with this command, intel's driver seems to be correctly configured, unity is running, kde too, openglx is working and I can switch between this two cards, the discrete nvidia-card is perfectly working, and nvidia-prime too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1263458 Title: no OpenGLX with Nvidia-prime and the discrete card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1263458/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
