 Posted: Wed Feb 08, 2023 4:06 am Post subject: [SOLVED] Laptop special key has no scancode |
 |
|
Hello,
My HP laptop has a special key which, in Windows, is supposed to open up a program called "OMEN Gaming Hub"; the program doesn't interest me, but seeing as how it would be a waste to leave the key unused, I've decided to turn it into a compose key, due to the fact that I also type in Spanish. But, the key doesn't show in xev while inside of xorg, or showkey while in a tty.
I kept investigating, and found in the Arch Wiki that the scancode might be found in dmesg, but instead this message is printed every time the key is pressed:
| Code: | | hp_wmi: Unknown event_id - 29 - 0x21a5 |
I tried using 0x21a5 as a scancode with setkeycodes, binding it to an unused keycode, but got the following error message, which I suppose means 0x21a5 is no a valid scancode:
| Code: | $ setkeycodes 21a5 240
setkeycodes: failed to set scancode 21a5 to keycode 240: ioctl KDSETKEYCODE: Invalid argument |
Here is my full dmesg.
I'll be grateful for any help I can get!

| Do you have HP_WMI enabled in your kernel config? |

I think so
| Code: | $lsmod | grep hp_wmi
hp_wmi 24576 0
platform_profile 16384 1 hp_wmi
sparse_keymap 16384 2 hp_wmi,intel_hid
rfkill 28672 4 hp_wmi,bluetooth,cfg80211
wmi 32768 4 hp_wmi,video,wmi_bmof,mxm_wmi |
| Code: | $zgrep HP_WMI /proc/config.gz
CONFIG_HP_WMI=m |

I believe I've found the reason for which this doesn't work, according to this mail thread, the OMEN key is supposed to enter the hp-wmi driver in the next merge window, which by the date the mails where sent I assume refers to kernel 6.2.
I'll be either trying to apply the patch submited on the thread, or waiting for the dist kernel of 6.2.0, as my hardware being new has caused headaches with manual configs 
I'll be marking the thread as solved if the patch resolves my issues  |
