Matebook 13 2020 (intel GPU / i5-102100U) - Arch linux with sway

This is to say a big thank you for your detailed guide and help with the matebook. Unfortunately there is no other area where I can write about this.

My question is that I cannot set manually the batery charging levels even with root for some reason. I found a script (I cannot find it again) to set the levels at boot using systemd.

I was using first Manajaro KDE and fractional scaling as well as hardware video decode for chromium work out of the box.

Then onto arch with sway (new to both so a bit of a learning curve) and setting the scale to 1.5 in the sway settings works fine but only for wayland apps.

Now I am using Arch with sway without fractional scaling. This might not suit everyone (as I don't use a second monitor) but I managed to get everything working in wayland and xwayland with no blurriness.

Some gtk apps will scale fine with gsettings (i.e firefox)
gsettings set org.gnome.desktop.interface text-scaling-factor 1.5

Electron apps will scale as well by settings the xft.dpi in the ~/.Xdefaults file (I set mine to 144).

QT apps scale as well.

Obviously it's a mess to setup but the result is well worth it but again only when using the laptop screen.

Anyway big thank you again for your work and it is amazing that I do not hear the fan go of once on Arch where in windows as soon as it starts it goes loud for quite some time before settling.

CPU heating after kernel update 5.3

Anyone faced a problem?

Updated my
Matebook to Linux Mint 19.3 along with linux kernel
4.15 --> 5.3

The CPU temp went crazy
This is just after a few minutes of usage (fans are active)
Had to enable nvidia drivers (with them CPU temp seems to be more stable)

But the problem is that the laptop is doing nothing and it show 50+ CPU temp
Downgrade kernel or upgrade? :)

On Windows 10 everything works well, and no problems with CPU temp

Do you have any recommendation?

About Touchpad Scrolling Sensitity

Just wanna know, when scrolling, do you feel any jerkiness about the touchpad? I filed a bug about that: https://gitlab.freedesktop.org/libinput/libinput/issues/453

Trackpad tap sensitivity?

I'm finding that the trackpad is too sensitive for my tastes, especially when you want to use tap-to-click. By default, approximately one skin cell is needed to trigger the tap event.

This page shows how a Linux user might change trackpad sensitivity:

xinput --set-prop [device number] "Synaptics Finger" 50 80 257

which seems to work for everyone else, can't help us, because MateBook trackpad doesn't seem to have "Synaptics Finger".

Anybody got a solution? Not sure if anybody else cares about this issue, or if I should just learn to keep my paws off the pad.

Russian Language Support

Hi Evgeny, add please russian language for russian users linux on matebook. And update please information for MateBook 13 2020 and AMD Edition. Big thanks :)

Issue with Huawei WMI and TLP - no boost frequency

Ever since I'd installed Huawei WMI I've noticed that the CPU won't boost. Its maximum frequency stays where I've set "CPU_SCALING_MAX_FREQ_ON_BAT" in TLP. Even manually setting TLP mode to AC (sudo tlp set ac) does not help. The only way I can get it to boost is if I reboot with the power cable plugged in.
Has anybody else noticed this/knows how to fix it?

OS: Ubuntu 19.04

Battery protection resets after reboot

I am setting the battery protection levels using the /sys/devices/platform/huawei-wmi/charge_control_thresholds, but after a reboot they go back to 0 100. Is there a way of making it persistent that doesn't involve making a script that runs on boot?

Disable wifi switch?

I don't really see the purpose of having a wifi switch in my day to day life. I've only pressed it by accident (or when cleaning something off), often causing me to wonder what caused my wifi to drop. If I want to disable wifi, I can do so fairly quickly already with just a few key presses.

Is it possible to disable the wifi toggling key, and/or does somebody have any tips on how to achieve this? It would be especially cool if I could re-purpose it for something more useful (bringing up a wifi menu?), but given that it's probably a hardware switch, I'm not sure if that's possible.

Compatibility with Matebook D 14 AMD ?

I have Ubuntu installed on my Huawei Matebook D 14 (with AMD Ryzen processor). Do you think this method will work on the BIOS provided for this laptop? Is there anything I should be aware of before trying it out?

Unable to change mouse acceleration on Kubuntu 2020.

I've got the new AMD version. Tried most of the solutions from the stack answers related to ubuntu LTS 16 and 18, tried a lot including xset and different xorg configs but to no avail. Was proposed to install the mtrack driver recently but after that, I'm still unable to fully disable the touchpad acceleration.

Battery protection not working

Hi, I can't seem to get the battery protection to work.
I am using a Matebook 13, running on Ubuntu 18.04 initially. I followed the instructions to install the Huawei-WMI drivers using dkms tarball. I used the version 3.2 one since that version of Ubuntu had linux kernel 5.0.
However, after installation I couldn't find the threshold parameter files for controlling the battery protection. Am I doing it right?
-->"Battery protection can accessed from either /sys/class/power_supply/BAT0/charge_control_{start,end}_threshold or /sys/devices/platform/huawei-wmi/charge_control_thresholds"

Or did I misunderstand the instructions?
I then tried to upgrade to ubuntu 19.10 to be able to use the latest version of the drivers, but it still doesnt work.

Could somebody help me out?

Matebook 13 2020 i7: unkown device found as a battery

Hi,
I don't know if it is the right repo to post that but since I installed ubuntu on my computer I got an unknown device called ELAN224A:00 04F3:2841:

  ID-1: BAT0 charge: 35.4 Wh condition: 42.3/41.6 Wh (102%) 
  model: DYNAPAC HB4593J6ECW-31T0 status: Charging 
  Device-1: hid-0018:04F3:2841.0002-battery model: ELAN224A:00 04F3:2841 
  charge: N/A status: N/A ```

Does anyone got that problem or know what is this device? (Possibly wrongly detected as a battery)

so the command I used to generate the bios.cab in this case was

./firmware_packager --firmware-name HuaweiBIOS --device-guid 4ab52f4e-04c0-47ec-af33-a4f5c28ce0b7 --developer-name Huawei --release-version 0.1.28 --exe ./BIOS_1.28.exe --bin ./UEFI_FW.bin --out bios.cab

Might be useful to add this info in README, especially for those less familiar with all this.

headphone jack detection

Try this, it works for me.

cat /etc/modprobe.d/sound.conf
options snd_hda_intel model=dell-headset-multi

Is it possible to add fingerprint support?

Any update how Matebook 13 2020 works?

Hello, I want to buy Matebook 13 2020 with Ryzen 7-3700U, RX Vega 10 [code: Heng-W29A]. Is there a update somewhere how it works with linux?
Regards.

Audio jack after suspend

I did as you wrote under audio section.
sudo sh -c "echo 'options snd_hda_intel model=dell-headset-multi' >> /etc/modprobe.d/sound.conf"
Seems to work ok, but after suspend, it doesn't work anymore.
When plugging in headset after suspend, nothing happens, need a new reboot in order to use headset.
alsactl restore after suspend does not work.

alsactl restore alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: File exists alsa-lib main.c:1021:(snd_use_case_mgr_open) error: failed to import hw:0 (empty configuration) Found hardware: "HDA-Intel" "Realtek ALC256" "HDA:10ec0256,19e5320f,00100002" "0x19e5" "0x3e09" Hardware is initialized using a generic method

Have been googling but can't really find anything that works.
Any suggestions?

Huawei Mate Pro X 2020 and battery level control

I have a Huawei Mate Pro X 2020 (the one with i7 10510 U).

Do you expect that this script:

https://github.com/nekr0z/linux-on-huawei-matebook-13-2019/blob/master/batpro

Will work on it? Or is there a risk it will break stuff as the script is given for Matebook 13 according to the comments?

If it is expected to work on the MPX20, can you update the comments to make it clear to everybody? :)

USB-C to HDMI, then HDMI to VGA adapter not working

If you use an HDMI to VGA adapter at the HDMI output of the USB-C to HDMI adapter, the output looks bad. It has vertical lines and weird colors and borders (photo below). However, it looks fine using the same setup on the same laptop on windows. Therefore, it must be a driver issue.

My adapter is not the Matedock 2. It is a generic USB-C to (USB-C input + USB-A output + HDMI output). But still, the HDMI output of my adapter is working on linux, as I tested it on some HDMI TVs. The issue appears only when a secondary video adapter (to VGA) is placed and only on linux.

power button and keyboard

The power button should work when you keep pressing it in 1 second.

Touchpad log floods issue has been fixed in mainline kernel
https://patchwork.kernel.org/patch/10750063/

The keyboard switches are all works in my setup(arch+mainline kernel+deepin DE)
except Huawei key,but it do generate xev event

Fractional scalling - cuted desktop

What Im doing wrong? Could you please help me guys?
I have Matebook 13 with Intel UHD Graphics 620 OS: elementary OS 6

Mic led

Hi,

After looking at the DSDT table, I've come to these methods SMLS and PAFF which seem to turn something on and off, and also called from the AMW0 device (WMI device) in SSDT5. Using a tool like acpi_call could you provide the return values and observe any changes to your system using the following?

$ echo "\_SB.PCI0.LPCB.H_EC.ECCC 0x48 0xA0 Zero Zero" | sudo tee /proc/acpi/call
$ sudo cat /proc/acpi/call
$ echo "\_SB.PCI0.LPCB.H_EC.ECCC 0x48 0xA1 Zero Zero" | sudo tee /proc/acpi/call
$ sudo cat /proc/acpi/call
$ echo "\_SB.PCI0.LPCB.H_EC.ECCC 0x45 0xA0 Zero Zero" | sudo tee /proc/acpi/call
$ sudo cat /proc/acpi/call
$ echo "\_SB.PCI0.LPCB.H_EC.ECCC 0x45 0xA1 Zero Zero" | sudo tee /proc/acpi/call
$ sudo cat /proc/acpi/call

Thank you!

Tested : Matebook 13 2020 AMD Ryzen 5 3500

All of the above tweaks were tested and the same results were obtained on the 2020 16GB ram, AMD Ryzen version of the Matebook 13 on Elementary OS.

Tested: Matebook 13 2020 with intel i5 10th generation cpu

Hi all,
I just wanted to report that I was able to run Linux Mint 20 Cinnamon and Kubuntu 20.04 flawlessly. Every functionality in the matrix on the README file works except fingerprint reader of course. Fn keys are fully functional.

Kubuntu is especially smooth on 8gb RAM.

I also find Slimbookbattery tool particularly useful for creating energy profiles.

What do you think of Ubuntu support?

What is the maximum battery life you had with matebook 13 in your installation?

I wanna confirm if im the only one experiencing a fast battery depletion in my huawei matebook 13
its like 2 and half hours then the batery runs out..

before in windows im getting 6-7 hrs ...

most of the time im just surfing web, and coding, and compiling stuff...

i should be getting a decent amount of batterylife like before in windows..

If anyone have a good advice please share it
