I have installed the above mentioned OS on a 15-year old IBM Thinkbad (t-43 / 1871 series).
I only care about the CAPS lock LED. Don't care about the others. Have reviewed some basic topics regarding setleds or similar but nowhere have I seen or understood exactly how to enable toggle. I have seen commands on how to manually turn the light on or off at will. That's silly, why should I have to do that. I want it to work the way it's supposed to: toggle on/off so that I know when I'm in caps on or caps off mode.
Can anyone suggest what amendments I need to make so that I can enable it? I would prefer solutions that don't require downloading extra software (remember this is a text-only interface that I have) as I want to keep the system light. I could do with some light scripting I suppose, but I'm really hoping there is a line somewhere in a system file that I need to amend to make this work. Otherwise open to some more involved solutions I guess. Thanks!
echo 1 | sudo tee /sys/class/leds/input45\:\:capslock/brightness
to see if that works. If it does, there's an answer for you at https://askubuntu.com/a/851093/197910 . As to your bonus question, please click [edit] and remove it, and make that a new question; house rules are, one issue per question, so the site becomes a giant FAQ. – K7AAY Sep 16 '19 at 21:12
