for me, xev gives this output for brightness-down:
| Quote: | RRNotify event, serial 48, synthetic NO, window 0x6200001,
subtype XRROutputPropertyChangeNotifyEvent
output eDP1, property Backlight, timestamp 76651476, state NewValue |
xbindkeys -k gives this output for brightness-down
| Quote: | "(Scheme function)"
m:0x0 + c:232
XF86MonBrightnessDown

It's very strange you get nothing from that button

I found the solution in Thinkwiki, in section Hotkeys:
| Quote: | # cat /proc/acpi/ibm/hotkey
status: enabled
mask: 0x0000ffbb
commands: enable, disable, reset, <mask>
# echo enable,0xffffffff >/proc/acpi/ibm/hotkey
# cat /proc/acpi/ibm/hotkey
status: enabled
mask: 0xfffffffb
commands: enable, disable, reset, <mask> |
With mask 0xffbb did not work, after enabling all (whatever it is) brightness down key works again.
On this page is section Speichern is given how to pass this to kernel module at boot:
| Quote: | # cat /etc/modprobe.d/thinkpad_acpi.conf
options thinkpad_acpi experimental=1 fan_control=1 hotkey=enable,0xffff8f bluetooth=enable |
