Lennart Poettering on Nostr: Did you know you could control brightness of the red dot on the i of the "ThinkPad" ...

Did you know you could control brightness of the red dot on the i of the "ThinkPad" on the top-side of your thinkpad? I sure didn't:

this turns it off:

```
echo 0 | tee /sys/class/leds/tpacpi\:\:lid_logo_dot/brightness
```

and this turns it on:

```
echo 255 | tee /sys/class/leds/tpacpi\:\:lid_logo_dot/brightness
```

I don't really know what this information is good for, but hey, isn't it awesome to have a 1px display on the outside of your laptop?
