Ubuntu – Ubuntu 16.04 + Nvidia Driver + Encrypted harddrive = Blank screen

Where/When do you get the blank screen? Is it when the grub menu should appear upon boot, or when the Ubuntu Unity login screen should appear? If it's the latter, try the following:

1. Add nomodeset on your Ubuntu grub entry. Highlight the entry you use to boot, press e, then add replace

   ...ro quiet splash ...

   with

   ...ro nomodeset quiet splash ...

If that boots to the login screen correctly, press Ctrl + Alt + F2, login, then run sudo prime-select intel. Then reboot and see if that fixes it.

Also, how are you installing NVidia drivers? DOuble-check at nvidia.com if you're using the correct ones.

From Nvidia customer service.... The following worked for me:

NVIDIA Driver Installation for Ubuntu 16.04

for Ubuntu 16.04, please try the following manual driver installation procedure:

1. blacklist open source nouveau driver by the command

   sudo printf "blacklist nouveau\nblacklist lbm-nouveau" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf 
   
   blacklist nouveau
   blacklist lbm-nouveaulisam@Atlas-PC:~$
   

to update the boot process run the command

    sudo update-initramfs -u 

    update-initramfs: generating /boot/initrd.img-4.4.0-36-generic
    W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1.bin for module i915_bpo
    W: Possible missing firmware /lib/firmware/i915/skl_guc_ver6.bin for module i915_bpo

Reboot

2. use ctrl+alt+F1 to go to a console, then login and use the command

   sudo service lightdm stop (command to exit the gui) 
   

3. change directory to the Download folder where you usually download the NVIDIA driver

cd /home/usr/Downloads

run sudo sh and follow on screen instructions

    sudo sh ./NVIDIA-Linux-x86_64-367.44.run

It may say that the pre-installation script failed and do you want to continue and answer Yes.

    The target kernel has CONFIG_MODULE_SIG set, which means that it supports cryptographic signatures on kernel modules. On some systems, the kernel may refuse to load modules without a valid signature from a trusted key. This system also has UEFI Secure Boot enabled; many distributions enforce module signature verification on UEFI systems when Secure Boot is enabled. Would you like to sign the NVIDIA kernel module?

    <Install without signing>

I tried installing without installing and I get an error message saying I needed to sign the kernel module or signing was necessary for secure boot up.

I tried to disable secure boot:

plug in USB Restart and enter BIOS Advanced mode> secure boot Windows UEFI mode OS Save secure boot keys Select USB drive as file system Saved four key files PK, KEK, DB, DBX to USB Delete PK to disable secure boot Save and restart with Other OS type and Secure Boot state disabled

    WARNING: Unable to find a suitable destination to install 32-bit comptability libraries.

    <OK>

    Would you like to run the nvidia-xconfig utility to automatically update your X configuration file so that NVIDIA X driver will be used when you restart X? Any pre-existing X configuration file will be backed up
    <YES>

4. reboot or run this command to start the gui:

   sudo service lightdm start
