fbkeyboard: New framebuffer console keyboard tool

This adds a keyboard for framebuffer consoles. Tested on Nexus 5 and PinePhone. Works well with user interface "none" (No graphical environment). Requires /dev/uinput (kernel config CONFIG_INPUT_UINPUT)

Some screen tuning recommended for seamless use:

stty rows 40 (value depends on actual console size and font)

Cursor keys, scrollback and vt switching is also supported:

This is awesome! Could it be used to replace osk-sdl for entering passwords in initramfs for unlocking a luks-encrypted rootfs?

I'm a bit worried about screen tuning, that stty rows 40. When should this be executed? In each real terminal (not in ssh session)? You are adding an openrc service in !1013 (merged), should that command be placed there or it won't work?

Now that I have a PinePhone let me test this first..

By Alexey Min on 2020-03-10T20:55:01

Requires /dev/uinput (kernel config CONFIG_INPUT_UINPUT)

pinephone:~$ zcat /proc/config.gz  | grep UINPUT
# CONFIG_INPUT_UINPUT is not set

Default pine64 config does not have that (/dev/uinput: No such file or directory)

Add: I've filed !1051 (merged)

pine:~$ fbkeyboard
error: cannot open uinput device /dev/uinput: Permission denied
pine:~$ ls -la /dev/uinput
crw-------    1 root     root       10, 223 Jan  1  1970 /dev/uinput

this needs more work :( nothing works out of the box

Probably needs some udev rule to assign the correct permissions on the device file? After doing

pine:~$ sudo chown root:input /dev/uinput 
pine:~$ sudo chmod g+rw /dev/uinput

it works: image
