NAME¶

BUFFYBOARD - Touch-enabled framebuffer keyboard (not only) for vampire slayers.

SYNOPSIS¶

buffyboard [OPTION]

DESCRIPTION¶

Buffyboard is a touch-enabled on-screen keyboard running on the Linux framebuffer. It's primarily intended for vampire hunting1 but you can also use it as a general purpose keyboard.

Buffyboard uses LVGL for input processing and rendering. Key events are forwarded directly to the kernel via a uinput device. Since the latter emulates a hardware keyboard, the terminal keymap must match with buffyboard's layout or else on-screen keys might not produce the correct result.
