Installation
Use
F1
or
Fn+F1
to enter UEFI/BIOS setup utility. You must disable
Secure Boot
to be able to boot from the installation media.
Secure Boot
See
Secure Boot
for general setup.
Note
Replacing the Microsoft's platform keys with your own (by running
sbctl enroll-keys
) is safe and does not brick the laptop, but it is not known as of 2023-06-01 what exact impact on internal devices it causes or if there is any device firmware validation at all.
Fingerprint reader
The fingerprint reader is built-in on the button and does not require pressing the button itself.
27c6:530c
requires a proprietary driver which can be obtained here
libfprint-2-tod1-xps9300-bin
AUR
.
04f3:0c4d
works out of the box and doesn't require a proprietary driver.
27c6:55a2
is currently in the works of reverse engineering.
[1]
[2]
The fingerprint reader doesn't work well with the default
fprint
because the sensor works by touching the sensor, not swiping the finger over the reader, hence it requires
libfprint-tod-git
AUR
. It is very precise:
fprint
only saves five finger samples which are not enough for different finger placements.
Screen rotation
Install
iio-sensor-proxy
for automatic screen rotation to work.
Power and Performance management
Note
Tools like
tp_smapi
or
tpacpi-bat
do not work with this device.
To tweak CPU power and performance preferences, see
Dell XPS 13 2-in-1 (9365)#Reduce throttling
as Lenovo's and Dell's Intel CPUs use the same interfaces.
To set the Battery Conservation Mode, see
Laptop/Lenovo#Battery conservation mode
Desktop Environment specific tools can be found over the internet to set everything up with GUI.
Fan control readings do not work yet and managed by the BIOS by default.
Offline USB charging can be turned on(1) or off(0) with:
# echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/usb_charging
Platform profiles
ACPI platform profiles can be managed manually via
sysfs(5)
at
/sys/firmware/acpi/platform_profile
or automatically via
tlp
or
power-profiles-daemon
. Available profiles can be viewed with
cat /sys/firmware/acpi/platform_profile_choices
.
HuC firmware
To enable HuC firmware loading for offloading media decoding functionality, see
Intel graphics#Enable GuC / HuC firmware loading
.
Lenovo integrated pen and touchscreen (Wacom)
See
Graphics tablet
for general installation procedure.
In late userspace
libwacom
does not have a tablet definition for the
i2c:056a:5269
device ID yet
[3]
.
It is possible to add your own definition instead so other programs such as
gnome-control-center
can recognize and configure the tablet:
/usr/share/libwacom/isdv4-5269.tablet

Name=ISDv4 5269

In early userspace
Loading drivers for input devices early provides a possibility to use programs such as
unl0kr
AUR
for unlocking disks with the GUI.
Required drivers to load into
initramfs
are:
evdev hid_multitouch i2c_hid_acpi intel_lpss_pci intel-lpss uhid uinput mac_hid i2c_smbus i2c_i801 hid_multitouch i2c_hid_acpi usbhid wacom ideapad_laptop lenovo_ymc think_lmi hid_generic mousedev
Function keys
Since the release of Linux 6.5, the
ideapad-laptop
driver has been updated to support extra hotkeys found on this laptop.
