Thinkpad T510 and leds

X-dark · 2011-01-14 15:16:18

Hi,
The caps lock, the mute speaker and the mute microphone leds are not working on my T510 laptop. This is my professional laptop and my coworkers who run Debian or Ubuntu have no problem with them.

I've tried with xset and with setleds and it does not work either.

As anyone has an idea of what could be missing for those leds to work ?

When you load thinkpad_acpi check dmesg. It should have led control, and tell you which leds it detected. Then check (IIRC) /sys/devices/platform/thinkpad_acpi/leds

Thanks but I don't see anything related to those leds in dmesg :

As a temporary workaround I'm using ledmon to output caps and num lock status into xmobar.

I've added ledmon into AUR: http://aur.archlinux.org/packages.php?ID=45804

My mute speaker LED works. The microphone one does not. None of the buttons work under arch. I've been meaning to map them as a keybind to amixer, but haven't. Did yours autodetect? Do they work?

Here is the relevant part of my xbindkeysrc:

#LowerVolume
"amixer -q set Master 1- unmute"
    m:0x0 + c:122
    XF86AudioLowerVolume 

#RaiseVolume
"amixer -q set Master 1+ unmute"
    m:0x0 + c:123
    XF86AudioRaiseVolume 

#TouchpadToggle
"/bin/bash /home/cgirard/touchpad.sh"
    m:0x0 + c:199
    NoSymbol

And the corresponding touchpad.sh:

#!/bin/bash

if [ `synclient -l | grep TouchpadOff | gawk -F '= ' '{ print $2 }'` -eq 0 ];
then
    synclient TouchpadOff=1
else
    synclient TouchpadOff=0
fi
