For me the following solution worked: 1. Install the kernel
linux- image-3.15.0-031500rc2-generic_3.15.0-031500rc2.201404201435_amd64.deb and the headers linux-headers-3.15.0-031500rc2_3.15.0-031500rc2.201404201435_all.deb linux-headers-3.15.0-031500rc2-generic_3.15.0-031500rc2.201404201435_amd64.deb then reboot. 2. Install nvidia-331, bumblebee and primus sudo apt-get install nvidia-331 bumblebee bumblebee-nvidia primus 3. Edit the bumblebee.conf file sudo gedit /etc/bumblebee/bumblebee.conf line 22: Driver=nvidia line 55: KernelDriver=nvidia-331 line 58: LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331 line 61: XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules save and reboot Check if your nvidia card is working with optirun glxgears -info -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288572 Title: Nvidia driver does not work in Ubuntu GNOME trusty "14.04" (Optimus laptop) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1288572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
