I also am facing the same issue and also boot to tty1. I'd be happy to provide any further information to help solve this.
P.S. If it is of any use, this also happened when I tried installing nvidia drivers on a new Fedora 23 installation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571225 Title: X does not start (nvidia-340 / optimus / ASUS K53SV) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-340/+bug/1571225/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
