I'm on Ubuntu MATE 16.04.1 and I changed graphic card to GeForce 8600GT and now I can't enter LUKS password on boot after installing NVIDIA propriatary drivers (I tried 304.135 and 340.102). Keyboard does not work there, I only have such screen and I can't enter anything:

enter image description here

To boot my OS I need to go through recovery mode and it boots fine, but I would like to fix it by perhaps changing that passphrase screen to text-mode. I know that there should be such mode for this as I have it on another machine with another GeForce, only thing that it's on 14.04 and it switched to text-mode automatically right after installing NVIDIA driver.

How do I do this on 16.04?

PS. I've tried THIS solution (both wxh and text) and it does not work for me - not any passphrase screen appears...

  • Did you try installing nvidia-375 from apt? – Shreyash S Sarnayak Mar 30 '17 at 13:40
  • Same issue, but can't even boot to recovery mode on 375 - getting FAILED on some Braille Device Support... – GreggD Mar 30 '17 at 15:28

    What happens if you remove the boot options quiet splash? You can do so quickly if you select a Grub entry, enter editing mode with the keyboard shortcut "C", edit the line starting with linux accordingly and press Ctrl+X to execute the listed commands. – David Foerster Apr 2 '17 at 23:43

    Oh! So simple! Needed to remove it from /etc/default/grub as Ctrl+X does not work here... and it looks like recovery mode, only don't need to go through GRUB and recovery mode, so it's good enough for me :) If you want, you can make an answer out of this, I'll give you those points. – GreggD Apr 3 '17 at 12:25

I have enabled this on my Ubuntu 16.04 server that has XFCE installed.

Edit /etc/default/grub with your text editor of choice, and remove the option quiet splash, and then if this does not work I would suggest also adding GRUB_GFXPAYLOAD_LINUX=text on a new line in /etc/default/grub. Remember, after you make a change to the grub config file, you should always run

sudo update-grub

to apply the changes.
