NAME

UNL0KR - LVGL based initramfs disk unlocker

SYNOPSIS

unl0kr [OPTION]

DESCRIPTION

UNL0KR is a disk unlocker for the initramfs based on LVGL. By using LVGL and rendering directly to the framebuffer it can work without relying on GPU hardware acceleration. This makes for much more managable initramfs sizes.

Unl0kr utilises the CRYPTTAB_TRIED variable. Upon completion, the entered password is printed to STDOUT. All other output happens on STDERR.

-g, --geometry=NxM[@X,Y]
Force a display size of N horizontal times M vertical pixels, offset horizontally by X pixels and vertically by Y pixels.

-h, --help
Print this message and exit.
