hwdb not updating on HP Chromebook 14

I'm on a A HP Chromebook 14 and I read threw https://wiki.archlinux.org/index.php/HP_Chromebook_14 And I wanted to make the F 1-10 keys to function. I have install arch before on many different matches  I placed

evdev:atkbd:dmi:bvn*:bvr*:bd*:svnHewlett-Packard*:pnFalco:pvr*
 KEYBOARD_KEY_3b=f1
 KEYBOARD_KEY_3c=f2
 KEYBOARD_KEY_3d=f3
 KEYBOARD_KEY_3e=f4
 KEYBOARD_KEY_3f=f5
 KEYBOARD_KEY_40=f6
 KEYBOARD_KEY_41=f7
 KEYBOARD_KEY_42=f8
 KEYBOARD_KEY_43=f9
 KEYBOARD_KEY_44=f10
 KEYBOARD_KEY_db=leftmeta 

in to

 /etc/udev/hwdb.d/90-chromebook-keyboard-fix.hwdb 

and rebuilt hwdb.bin using

 udevadm hwdb --update 

as root. I rebooted and it did not work.

Thanks

Re: hwdb not updating on HP Chromebook 14

Hi Hexmaster111 and welcome to the Forums

can you please post the output of the following command?

cat /sys/class/dmi/id/modalias

Also can you also explain why do you think your hwdb rule does not work? For example does the key combination Ctrl + Alt + F2 switch to the tty2? Can you post the output of xev when you press one of the F1-F10 key?

Re: hwdb not updating on HP Chromebook 14

Hi,
I have the same issue since the last update. I noticed there was a new kernel. My guess is, that this is the reason.

My configuration is the following:

keyboard:usb:v*p*
keyboard:dmi:bvn*:bvr*:bd*:svn*:pn*:pvr*
 KEYBOARD_KEY_3a=leftctrl # CapsLock to ctrl
 KEYBOARD_KEY_38=leftmeta # swap alt
 KEYBOARD_KEY_db=leftalt  # with meta key

The hwdb.bin file seems to be updated (correctly?), the timestamp is correct and

cat /etc/udev/hwdb.bin |egrep "KEYBOARD_KEY_3a.{10}" -ao

resulted in

KEYBOARD_KEY_3aleftctrl

.

I also rechecked the hex keycodes with  evtest (before and after reboot):

Event: time 1435685454.442361, type 4 (EV_MSC), code 4 (MSC_SCAN), value 38
Event: time 1435685454.442361, type 1 (EV_KEY), code 56 (KEY_LEFTALT), value 1
Event: time 1435685454.442361, -------------- EV_SYN ------------

Event: time 1435685454.508128, type 1 (EV_KEY), code 56 (KEY_LEFTALT), value 0
Event: time 1435685454.508128, -------------- EV_SYN ------------

Event: time 1435685457.144601, type 4 (EV_MSC), code 4 (MSC_SCAN), value 3a
Event: time 1435685457.144601, type 1 (EV_KEY), code 58 (KEY_CAPSLOCK), value 1
Event: time 1435685457.144601, -------------- EV_SYN ------------
Event: time 1435685457.187014, type 4 (EV_MSC), code 4 (MSC_SCAN), value 3a
Event: time 1435685457.187014, type 1 (EV_KEY), code 58 (KEY_CAPSLOCK), value 0
Event: time 1435685457.187014, -------------- EV_SYN ------------
Event: time 1435685457.187152, type 17 (EV_LED), code 1 (LED_CAPSL), value 0

And by the way the output of

cat cat /sys/class/dmi/id/modalias

is

dmi:bvnDellInc.:bvrA04:bd07/08/2010:svnDellInc.:pnLatitudeE6410:pvr0001:rvnDellInc.:rn04373Y:rvrA00:cvnDellInc.:ct9:cvr:

.
So that should match.

@Lord Bo, your is a different issue: since systemd 220 the udev hwdb ABI have changed so you should update your custom rules and use the new format, consult the wiki for more information: https://wiki.archlinux.org/index.php/Ma … Using_udev
