I've just done a fresh install of 15.10. After installing the nvidia drivers for my quadro 600, I was able to improve the tty resolution by setting:


in /etc/default/grub, but now when the password login screen displays, I'm unable to enter the password in the input box. I've tried ctl+alt+f1 and other things to try to enter it, but haven't found what works.

I'm able to enter it if I set nomodeset, but that puts me back at a low resolution.

  • Any solution to this? I'm having a similar problem after installing nvidia drivers. – Jeffrey DeLeo Jan 24 '16 at 4:33
  • No real solution. I had to drop it down into low resolution with nomodeset to be able to enter it. It's ugly, but I didn't ahve time to mess with it further. – labyrinth Jan 25 '16 at 21:45

    I did something similar - edited /etc/default/grub to change GRUB_CMDLINE_LINUX_DEFAULT to "", then "sudo update-grub". Low res startup, but can type in unlock passwd. – Jeffrey DeLeo Jan 28 '16 at 19:41
  • Here is my solution: realtechtalk.com/… What I found is that after a kernel update that I couldn't type the LUKS password. In my experience it is usually caused by not having the "extra" kernel modules installed. Even if you use quietboot or Esc to enter the password, you may find your system is still broken after booting due to missing other "extra" modules that you were using. – Areeb Soo Yasir Sep 13 '19 at 15:23
