MateBook 13 running Linux
Brain dump: MateBook 13 (Wright-W19) running Debian heavily inspired by lidel's documentation of running Linux on MateBook X.
Huawei MateBook 13, released in 2019, has at least two modifications (different CPUs, integrated vs. dedicated graphics). Both come with Microsoft Windows 10 and there initially was no information at all concerning Linux support.
I am running Debian on the more simple MateBook 13 variant, model Wright-W19. This repository documents what works and what does not.
Reportedly, it also holds true for at least one 2020 Huawei Matebook 13 (AMD Ryzen 5 3500) running Elementary OS.

Huawei provides downloadable BIOS updates packaged for Windows. With some effort, these can be installed from Linux.
To update BIOS, make sure
fwupdis installed. You'll also need firmware-packager script and
gcabthat it depends on. I strongly advice having a bootable USB drive for bootloader recovery close at hand, too. Laptop should be on AC power for firmware updater to work.
PLEASE read through all the steps before you start and make sure you have at least a vague understanding of the process! Don't hold me responsible if you trash your system or brick your BIOS!!!
.zipfile that contains a signature and another
.zipfile with the same name. You need that second
.zipfile, so extract it to the directory you have
2. ./firmware-packager --firmware-name HuaweiBIOS --device-guid 4ab52f4e-04c0-47ec-af33-a4f5c28ce0b7 --developer-name Huawei --release-version 0.1.0.5 --exe ./MateBook13BIOS1.05.zip --bin ./MateBook13BIOS1.05/WRIWU105.bin --out bios.cab
3. fwupdmgr install bios.cab
Reboot (or hibernate) and hold F12 upon boot to select updater from list of devices. It reboots again during the process, so make sure to press F12 during the second reboot, too, for the process to continue.
Now your new BIOS is installed and you may check its version holding F2 during the next reboot. However, your UEFI boot record is likely messed up as the result of Step 4, so your system won't boot from SSD any longer.
Fix your bootloader using the bootable USB drive. I used a Debian Live image with persistence that had
grub-efi-amd64and its dependencies pre-installed, so it was only a matter of mounting
sudo grub-install --boot-directory=/mnt/system/boot --bootloader-id=debian --target=x86_64-efi --efi-directory=/mnt/system/boot/efi
Your mileage may vary.
Out of the box fan control is very much acceptable, with fans starting up as processor heats up under load and shutting down when not required. In general, under "office workload" the laptop remains cool and fans remain switched off.
If you want correct CPU temperature displayed in
byobustatus notifications, add the following line to your
On KDE, Deepin and other Qt-based desktop environments, fractional scaling is supported without any hassle but this is not the case for GTK-based desktop environments such as GNOME and XFCE. Using Wayland can be an option, but the apps that don't support Wayland natively will still have issues such fuzziness all over the window. A workaround for Xorg allows for 150% scaling without any tear at the cost of a little performance drop: Copy
/etc/X11/xorg.conf.d/and reboot. It is worth noticing that kernels between 5.0 and 5.5 have known issues with desktop scaling, fixed in 5.5. Ubuntu users can use Ubuntu-18.04-HWE kernel that contains the fix and also is free of the log flooding issue.
Sound generally works OK out of the box, the only thing not working is headphones autodetection (i.e. it is necessary to manually switch from speakers to headphones and back). This can be fixed, as pointed out by ffftwo:
sudo echo "options snd_hda_intel model=dell-headset-multi" >> /etc/modprobe.d/sound.conf
You may need to reset ALSA after this for the headphones to work:
There's currently no way to make this model work in Linux, however, there's work in progress to make this happen.
Main battery features, such as current status, charging/discharging rate and remaining time estimates work out of the box.
Huawei's proprietary PC Manager allows to switch on battery protection with several modes for charge/discharge threshold while connected to AC power. For instance, it is possible to make the laptop maintain the battery charge between 40% and 70%, which is supposed to greatly reduce battery wear (batteries are known to lose capacity when constantly sitting at close to 100% charged). The problem is that Huawei PC Manager is a Windows-only piece of software.
You can use matebook-applet to have GUI on Linux for this functionality. Under the hood it utilizes Huawei-WMI device driver that fully supports Matebook 13, including settings for battery protection, since version 3.0. The driver only works with Linux kernel 5.0 and newer (you can install 5.2 from Debian Backports). Kernels 5.5 and newer have the sufficient version of the driver already included.
ioport(available as package in Debian) and needs to be run as root:
sudo batpro [help|status|off|home|office|travel]
The first three options are self-explanatory.
homesets thresholds to 40% and 70%,
officeto 70% and 90%,
travelto 95% and 100% (these are the three modes Huawei PC Manager makes available). You can also do
sudo batpro custom [1-100] [1-100]
to set the thresholds to any percentages you like. This batpro script is really a modification of a more general script by aymanbagabas, so you can use that one instead if you like. Both are based on a dirty hack, and the proper solution is using Huawei-WMI driver.
Battery protection works by not charging the laptop if battery is already above the minimal threshold when plugged into AC, and stopping the charging as soon as the battery charge reaches the maximum threshold. The battery controller is known to restore the thresholds to defaults after time: on MateBook X it is known to happen after a reboot or three, and Angry Ameba demonstrated (source in Russian) that battery controller settings get reset after several hours on a switched off MateBook 13. Obviously, Huawei PC Manager monitors this and restores these settings as required. Huawei-WMI driver and my script don't.
This behaviour may be really annoying: you hibernate your laptop, wake it up next Monday, work for several hours, plug it in for a night and go to bed, only to find out in the morning that battery protection is off and the battery stayed on 100% for good six hours. If you're using Huawei-WMI driver, this situation can easily be fixed using a solution provided by Rouven Spreckels (these pieces get installed automatically if you usematebook-applet's Debian repository):$ git clone https://github.com/qu1x/huawei-wmi.git $ cd huawei-wmi $ sudo make installYou may then use the same Makefile to set thresholds so that they are reinstated after wakeups and reboots:$ sudo make [off|home|office|travel]You can also add your user to thehuawei-wmigroup:$ sudo usermod -a -G huawei-wmi YOUR_USERNAME(naturally, you need to put your actual username instead ofYOUR_USERNAME). In this case you don't needsudoto set thresholds.
Beware, though, that if you plug the laptop in before waking it up, the magic won't work (knowing that Windows' behaviour is exactly the same may provide some consolation).
Suspend to S3 state works out of the box. For hibernation to work
Secure bootmust be disabled in BIOS. Laptop seems to wake up without any issues.
Keyboard mostly works out of the box, including the not-so-documented hotkeys (Fn+Left for Home, Fn+Right for End, Fn+Up for PgUp, Fn+Down for PgDn). However, Microphone Mute, WiFi Switch and Huawei keys don't work out of the box.
Version 2.0 of the same driver allows for the Microphone LED to work, too. This requires running kernel 5.0 or later (5.2 is avalable from Debian Backports).
Behaviour of the top row of keys on MateBook 13 is somewhat complex. By default, they behave as special keys (brightness, volume, etc.), but if you press them simultaneously with
Fnor any modifier (
Shift) they behave as F-keys (
F12). You can press
Fnonce so that an LED on it lights up, then the top row of keys starts behaving as F-keys, with or without any modifier (including
Fnitself). This behaviour can be lived with, but you can't do things like
F12, respectively, and pressing them with modifier forces them to be F-keys).
Since BIOS v1.05 this behaviour was changed slightly forPrtScandInskeys (F11andF12). WithoutFnkey, the keys work as follows:
| Key | Shift | Ctrl | Alt | | --- | --- | --- | --- | |F10| Shift+F10 | Ctrl+F10 | Alt+F10 | |F11| Shift+PrtSc | Ctrl+PrtSc | no keypress | |F12| Shift+Ins | Ctrl+Ins | Alt+Ins |
Still no way to doAlt+PrtSc.
Fortunately, Huawei's PC Manager has an option to invert this behaviour. If an option is activated (we call this option
Fn-Lock), the upper row of keys become F-keys, and act like special keys only when
Fnis pressed or switched on. In this mode other modifiers don't change behaviour, so it becomes possible to do
PrtSc. Unfortunately, PC Manager is Windows-only.
Huawei-WMI driver since version 2.0 makes it possible to use Fn-Lock on Linux. For those running Linux kernel older than 5.0 there's a simple script (you can download archive with this and the other script from releases page).
The script depends on
ioport(available as package in Debian) and needs to be run as root:
sudo fnlock [on|off|toggle|status]
GUI for this functionality is also included in matebook-applet.
General features like two-finger scrolling and three-finger touch work out of the box, more options can be made available by installing
xserver-xorg-input-synaptics. No pressure sensitivity or palm detection, though.
Out of the box touchpad floods system logs with error messages
incomplete report (14/65535)upon every touch - up to the point where rubbing your finger against touchpad produces 15% CPU usage by syslog. The corresponding patch is available in backported kernel 5.2 in Debian. If you want to use stock kernel instead, patching the kernel with adapted patch fixes this issue.
A quick (and, admittedly, dirty) way to patch a Debian kernel: ``` $ apt source linux $ cd linux-4.19.28 <<< or whatever version is current $ bash debian/bin/test-patches ../elan-touchpad-oldkernel.patch <<< or whichever one you're applying, and you can apply more than one here
<<< have a beer or three, this is going to take quite some time
$ cd .. $ sudo dpkg -i linux-image-4.19.0-4-amd64-unsigned4.19.28-2a~testamd64.deb <<< or whichever you've just compiled ```
Thanks to Angry Ameba for kindly supplying the information necessary to make battery protection and Fn-Lock work.
Eternal gratiude and enormous thanks to Ayman Bagabas for single-handedly developing Huawei-WMI driver and sharing tons of useful information.
Also thanks to Mert Demir for giving information about fractional scaling and adding the related info.
