I am using Ubuntu 16.04 and I have an Intel GPU and an Nvidia GPU. Previously I had installed the latest Nvidia driver for my Nvidia GPU, however, my computer was only using that GPU and ignoring the other. I am using cuda to run neural network projects and when training some large networks I ran into a lack of memory issue with the GPU. So to remedy this I thought Bumblebee would allow me to have more control over how I use my GPU's. HUGE MISTAKE

I followed the guide on Ubuntu wiki to install Bumblebee from this following the steps:

  1. Enable the Universe and Multiverse repositories in order to allow the bumblebee and Nvidia packages to be installed:

    sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generic

  2. Reboot

However after rebooting my screen was black. I could still hear the login sound that it makes when the login screen shows up.

Luckily I am dual booting windows on this computer, so I still have half a computer, that is how I am writing this question.

At this point, I do not care about Bumblebee anymore and I would just like to uninstall it so that I can use Ubuntu again. How can I do that if my screen is black?

Any help would be greatly appreciated.

  • After you hear the login sound press ctrl+alt+F1 - this should give you access to the login console. You can uninstall the last installed packeges by: sudo apt-get remove bumblebee bumblebee-nvidia primus. You can then reinstall the nvidia driver in the console and reboot the computer. – kukulo Dec 6 '18 at 10:06
  • I tried as you suggested pressing ctrl+alt+F1, however, this did not seem to do anything, unfortunately. – Eddy Schneeweiss Dec 6 '18 at 10:15
  • You can still boot with live usb and chroot to your system then use apt-get to uninstall the packages. – kukulo Dec 6 '18 at 10:21
  • as @kukulo said you can try to boot into a live cd. did you try bott into a rescue mode? ie at boot choose recovery and then check disks (this will enable you to write to disk) and then chooce an option to manage packages - remove bumblee as Kukulo suggest – 2705114-john Dec 6 '18 at 12:15
