Hey y'all,

I've been using Linux for some time now, and recently I switched to KDE Neon, because it works very well out of the box. And since full disk encryption is available, I'm using it. But how can I change the keyboard layout, resolution and verbosity of the decryption passphrase prompt? Currently, the keymap is QUERTY, and the resolution is ~800x600. Is it possible to make it QWERTZ and 1920x1080?

I've tried editing /etc/default/grub/, like writing GRUB_CMDLINE_LINUX_DEFAULT="keyboard keymap", but that didn't work, KDE Neon didn't boot after that.

Is just something cosmetic, but I want to be everything consistent in style.

Any help is appreciated, thanks in advance!
