It left me in the dark too (booting to text mode console) and i lost 3 hours looking for the problem. At first my solution was to manually load the nvidia-331 module with modprobe and then I found this bug report sating that bumblebee blacklists the nvidia drivers.
Uninstalling (apt-get remove) doesn't remove /etc/modprobe.d/bumblebee.conf but purging does (apt-get remove --purge). Now I'm wondering what will happen to not so tech savy users... In systems without dual graphics it prevents X from loading at all and even using ppa-purge to remove xorg-edgers packages does nothing (it was my first try) as /etc/modprobe.d/bumblebee.conf is still left behind. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1265570 Title: nvidia-331 update installs bumblebee [xorg-edgers] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1265570/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
