I run Ubuntu 16.04.

After reinstalling drivers for graphics card (nVidia prime) I got the following error while trying to boot:

Error: Driver 'ebridge' is already registered, aborting...

I solved this problem as follows:

  1. Menu GRUB2 - Advanced options for Ubuntu
  2. Ubuntu with Linux 4.4.0-21-generic (recovery mode) //kernel version is important!
  3. When OS is booted, input the commands in terminal

    sudo apt-get purge nvidia*
    sudo apt-get purge nvidia-settings
    sudo apt-get purge nvidia-prime
  4. Reboot

  5. Boot with new kernel version (4.4.0-23-generic)
