It is now (as of recently) generated by gpu-manager (which is part of ubuntu-drivers-common). Actually quite a few changes have landed to various components related to nvidia prime since you posted the correct results.
I am marking this bug as fix released since I'm fairly confident the gnome-shell issues are resolved. I also believe that gdm will work properly once the case of non-existent display is fixed. If there are further gdm issues after that please follow up that issue on Bug 1262068. Please file a new bug for the non-existent display issue with xrandr outputs and Xorg logs, hopefully the Ubuntu devs will have more of an idea to figure that out! ** Changed in: gnome-shell (Ubuntu) Status: Triaged => Fix Released -- 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
