Lenovo x220 functional keys stopped working

eDio · 2015-05-16 08:34:22

Recently functional keys on my laptop stopped working.
I can't say for sure, which update broke them, but downgrading from linux-4.0.2 to linux-3.19.3 hasn't solved that.

In dmesg output I see suspicious lines

I have similar lines in my dmesg on a Lenovo X200, but my keys all work just fine. Can you elaborate on the problem: specifically which keys are not working? How do you operationalize "not working": they no longer do what you want, they no longer produce any xev output, or produce the wrong xev output, they no longer are recognized by showkeys, etc?

Check the options in your firmware (BIOS) menus.

All those keys that control laptop external devices and sleep/hibernation/etc. (i.e. Fn + {F2..F8,F12,Home,End}), stopped producing xev output.

aurenar · 2015-06-14 19:23:43

The same happened to me after an update to 4.0.5 I don't get the dmesg messages tho.

xev also does not report any events when pressing any fn+[button] keys.

[ 2.786319] input: ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input7
# ls /sys/devices/platform/thinkpad_acpi/input/input7
capabilities device event6 id modalias name phys power properties subsystem uevent uniq
$ cat /dev/input/event6
<pressing keys>
nothing

Downgrading to 4.0.4-2 works for me.

Sorry for not replying at once, but I really had nothing to tell.

Thing fixed itself after suspend-resume cycle.
All I did was systemctl suspend, and then resume by holding fn button for few seconds. That's it. Never had issues after that. Currently on 4.0.5.

Maybe that'll fix things for you as well.
