Installation
To access the boot menu and UEFI, use F1
. Disable Secure Boot. UEFI boot works fine.
Accessibility
The UEFI user interface (both Vanilla and patched − see #Audio) is graphical. An option to switch to a text-based GUI is not provided. However, the options may be selected with the arrow keys and the values changed with F5
and F6
keys.
Function keys
By default, the Fn
key does not need to be pressed to toggle the alternative function of the FX
keys, and Fn+FX
actually sends the FX
key signal. This behavior can be reversed in the UEFI.

- The key is visible to
xev
and similar tools. - The physical key has a symbol on it, which describes its function.
- systemd-logind handles this by default.
- Press and release signals are sent on physical key press, nothing occurs on physical release.
Video
By default, tearing is apparent when playing videos. To fix, create the following:
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" EndSection
There seems to be issues with Chromium based GPU acceleration, so either disabling that via Chromium flags, removing xf86-video-intel, or adding the following options to /etc/X11/xorg.conf.d/20-intel.conf
:
Option "NoAccel" "true" Option "DRI" "false"
Audio
This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.
Additionally, you'll need to blacklist the snd_hda_intel
and snd_soc_skl
modules.
The amplifiers for the extra speakers are turned off by default and there is no available documentation on how to turn them on; more details on bugzilla.kernel.org#205755. There exists an unreleased patched firmware (from Lenovo) that turns the speakers on, see comment 59, now only available on a mirror. Latest official update (AUCN61WW) still present this issue, even though they were release after the beta version.
Thermals
Thermal shutdowns are a problem unless you install pstate-frequencyAUR or thermald.
pstate-frequency
pstate-frequencyAUR allows the user to define Turbo Boost behavior and maximum clock frequencies. The user should activate pstate-frequency.service
and pstate-frequency-sleep.service
for the setting to persist after suspend or reboot. Configuration files are located in /etc/pstate-frequency.d/
.
Changing the line PLAN_CPU_MAX=100
to PLAN_CPU_MAX=70
in /etc/pstate-frequency.d/02-balanced.plan
will throttle the maximum clock speed from 3.90 GHz to 2.70 GHz on AC. Moreover, the default plan of pstate-frequency will throttle the CPU to 30 % (around 1.2 GHz; see /etc/pstate-frequency.d/01-powersave.plan
) on battery power, removing the issue of thermal shutdowns.
thermald
A few changes are necessary for thermald to work as intended:
Add the following thermald config:
/etc/thermald/thermal-conf.xml
<?xml version="1.0"?> <!-- BEGIN --> <ThermalConfiguration> <Platform> <Name> Auto generated </Name> <ProductName>81Q9</ProductName> <Preference>QUIET</Preference> <ThermalZones> <ThermalZone> <Type>auto_zone_0</Type> <TripPoints> <TripPoint> <SensorType>SEN2</SensorType> <Temperature>80000</Temperature> <Type>Passive</Type> <CoolingDevice> <Type>B0D4</Type> <SamplingPeriod>8</SamplingPeriod> <TargetState>2147483647</TargetState> </CoolingDevice> </TripPoint> <TripPoint> <SensorType>x86_pkg_temp</SensorType> <Temperature>80000</Temperature> <Type>Passive</Type> <CoolingDevice> <Type>Processor</Type> <SamplingPeriod>1</SamplingPeriod> </CoolingDevice> </TripPoint> </TripPoints> </ThermalZone> </ThermalZones> </Platform> </ThermalConfiguration> <!-- END -->
You might wish to tweak the target temperature (i.e. 64000) if you are OK with your machine running a bit hotter.
Edit thermald.service
and remove --adaptive
and add --ignore-default-control
to the ExecStart
line:
ExecStart=/usr/bin/thermald --systemd --dbus-enable --ignore-default-control
Manual fan control does not work at all.
Power management
Battery Conservation Mode (charge to max 50%) can be set with:
# echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode
where VPC2004\:00
could vary depending on the model.
If shutdown is not working and the system hangs on "reboot: Shutting down", try adding intel_iommu=off
to your Kernel parameters.
Thunderbolt
Thunderbolt controller's PCIe address space is marked as "reserved" by the BIOS (handled by the e820
kernel subsystem). By default, Linux before version 6 ignores these addresses, thus making some devices (e.g. Thunderbolt docks) unable to operate correctly, and may even cause crash due to PCIe controller hanging, which in turn disconnects the NVMe SSD. A patch in the kernel has been merged, and dock are now working on mainline Linux 6.
Tablet Mode
By default, the kernel cannot detect when the device is folded keyboard-down (360 tablet mode), yoga-usage-mode-dkms-gitAUR adds a driver. If the desktop environment supports it (eg. KDE, Gnome, Sway) then the touchpad and keyboard will be disabled when the device is folded by default, and may offer more touch-friendly functionality.
