Problems Entering Password With Full Disk Encryption Edit on GitHub

There is a bug in the Plymouth splash screen which can cause issues inputting your password. This only affects systems with NVIDIA hardware.

The current work-around is to disable the splash screen while booting. To disable the splash screen on the first boot, tap ESC while booting to enter the GRUB menu. Press E to edit the default option, then delete the word “splash” from the second to last line, and press F10 to continue booting. If the system pauses with a maroon background shown, enter the full disk encryption password. Once booted, disable the Plymouth splash screen permanently by editing the GRUB configuration file with this command:

sudo gedit /etc/default/grub

And change this line:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

to this:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet”

Save the file, and run this command to make it permanent:

sudo update-grub
