Im using latest kernel and archlinux about huawei-wmi

[codeitlikemiley]

i manage to control the mic on off
by adding this to my i3 conf

bindsym XF86AudioMicMute		exec --no-startup-id amixer set Capture toggle && amixer get Capture | grep '\[off\]' && notify-send "MIC switched OFF" || notify-send "MIC switched ON" #f7

hope you can help me with screen brightness problem
cause if i use the xbacklight command
it just returns me this message

No outputs have backlight property

[aymanbagabas]

To use battery protection, you have to compile the latest driver from master and set charging thresholds from /sys/devices/platform/huawei-wmi/charge_thresholds as described in the readme.

matebook-applet is another project by @nekr0z. This is not the same project!

Brightness is handled through acpi_video. AMOF this driver would cause reporting brightness twice to OS, I'm working on a fix for this. You can try another DE like KDE or Gnome to get a fully working environment.

What is the output of acpi_listen and sudo evtest of 'Huawei WMI hotkeys' and 'Video Bus'? Try using something like acpilight or light instead of xbacklight.

F8 (DisplaySwitch) is actually not a hotkey, Huawei oddly mapped it to super+p which in Windows pops up the display switch sidebar and works the same in most Linux DEs at least on Gnome.

The driver has to be active to use F10 (Huawei management), it maps it to XF86Tools so if i3 picks that, you could bind it to anything else. By default, in Gnome and I believe KDE, XF86Tools opens up settings.

i have no luck compiling your repo

make -C /lib/modules/5.1.2-arch1-1-ARCH/build/ M=/home/uriah/Packages/Huawei-WMI modules
make[1]: Entering directory '/usr/lib/modules/5.1.2-arch1-1-ARCH/build'

but i do manage to make a work around on the screen brightness
ive installed brightnessctl
also the audio jack is detected but needs to be switch manually thru pavucontrol
btw heres my i3 conf
i did install some scripts from matebook 13 applet project like the batpro and fnlock

fn lock is different from fn toggled (led on) be aware of that!

I believe im missing some dependencies which is not explicitly define on the readme.
i tried on my other arch laptop , not huawei but ...
i tried to install archlinux lts kernel and headers
i believe the kernel-devel on arch is base-devel so i didnt install anything on that counterpart package

sudo pacman -S linux-lts
sudo grub-mkconfig -o /boot/grub/grub.cfg
sudo pacman -S linux-lts-headers
reboot

now my kernel is an lts kernel

I did try to cd to Huawei-WMI but it failed again, maybe because the laptop i used was not huawei matebook 13.

but it produces a different error now

I fucked up, but i manage to make it work the make command.
I did remove the linux-lts kernel and the linus-lts-headers

reinstall linux and linux-headers

sudo grub-mkconfig -o /boot/grub/grub.cfg
reboot
then go to Huawei WMI folder and make
no errors

Glad everything worked out. The errors you were getting were because of kernel < 5.0.
Closing this issue for now.

@aymanbagabas my Arch install doesn't have /lib/modules/$(uname -r)/updates/ (or rather, there is no "updates" folder). Should i create this updates folder? Or should I maybe replace the old kernel module in /usr/lib/modules/5.1.7-arch1-1-ARCH/kernel/drivers/platform/x86/?

[aymanbagabas]

@rien333 just create one or use dkms

[rien333]

Note this AUR package seems to work fine. (maybe mention it in the readme?)

Thank you, I'll do that sometime later. Especially that all the new features, version >3.2, are now merged into kernel 5.5.
