doesn't work on Fedora27/ Thinkpad L460

led $off
ec_sys is a stock kernel module: https://github.com/torvalds/linux/blob/master/drivers/acpi/ec_sys.c
Script has to run as root, input must be lower case.
Tested on T580, works.
@hirschnase: it is included in ubuntu, not sure about other distros
@kachini: your os might lack ec_sys too. let me know, if you figure out, how to write raw data to your laptop's gpio without ec_sys
@hirschnase: what distro?
Cool! Works fine with opensuse 42.3
I cannot get this to work. It runs, sure, but there is no action,
Specifics of this X131e:

not my project, but does this work? https://github.com/RichusX/thinkmorse
If you are using nixos you can have your LEDs permanently blink messages using the following module:

description = "The message to display in morse code";
};
devices = lib.mkOption {
type = lib.types.listOf lib.types.str;
default = [ "tpacpi::lid_logo_dot" ];
description = "The devices to use for morse code";
};
speed = lib.mkOption {
type = lib.types.str;
default = "0.1";
description = "Duration of a dit in seconds";
};
};
};
config = lib.mkIf config.services.thinkmorse.enable (
let
ditDelay = config.services.thinkmorse.speed;
thinkmorse = pkgs.writeShellScriptBin "thinkmorse" ''

Cool idea. And this ec_sys kernel module is available where?
