ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input16
Hi,
Hoping that is it possible:
How to inject key stroke or "button pressed" in /devices/platform/thinkpad_acpi/input/input16 ?
Website https://xyproblem.info says I should tell what the original
problem is. It is `rfkill list` reporting "hard blocked", not being
enable to use WIFI, `nmcli radio wifi` reporting "disabled".
Pressing "Function key with symbol of computer sending signal" has no
effect. Which could be caused by the horrible state of keyboard.
When keyboard is needed, is an USB-attached keyboard needed. Usual use
case of the laptop is "headless server, server with SSH access".
So I'm ask if
export KEYCODE=42
echo $KEYCODE > /devices/platform/thinkpad_acpi/input/input16
could cause "wlan radio enable"? Or should KEYCODE be another magic number?
What also would be helpfull, is knowning if
echo 4242 > /devics/platform/laptop_chipset/input/input17
could change brightness (or another visible effect)
