How to re-install Ubuntu 18.04 on a TensorBook

1

Unfortunately, due to BIOS limitations, you can’t just simply install vanilla Ubuntu 18.04. The TensorBooks need a modified set of linux kernel parameters in order to be able to use their GPUs and display. We’re working with the BIOS authors to modify the BIOS to not require this.

In the mean time, you can re-install Ubuntu 18.04 + Lambda Stack by following these steps:

  1. Install Ubuntu 18.04

  2. Log in, open a terminal and type

    sudo nano /etc/default/grub

    Then modify the /etc/default/grub file to so that the GRUB_CMDLINE_LINUX_DEFAULT looks like this:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_os_name=Linux acpi_osi= acpi_backlight=vendor"

    Save the file with [Ctrl]-[O] then [Enter].

  3. Type sudo update-grub in the terminal.

  4. Install Lambda Stack: Lambda Stack: an AI software stack that's always up-to-date

  5. Reboot the machine with sudo reboot

You should now have a system with Ubuntu 18.04 + Lambda Stack installed.
