Fixes

GPD Win Max 2020/2021

Touchscreen

If you are using Xorg, create the file: /etc/X11/xorg.conf.d/99-touchscreen.conf to rotate the touchscreen.

/etc/X11/xorg.conf.d/99-touchscreen.conf

Section "InputClass"
  Identifier    "calibration"
  MatchProduct  "Goodix Capacitive TouchScreen"
  Option        "TransformationMatrix"   "0 1 0 -1 0 1 0 0 1"
EndSection

Mute Key

The mute key does not send a release code. To fix it, create a new udev hwdb file under /etc/udev/hwdb.d/, and configure the key to trigger an automatic release event.

/etc/udev/hwdb.d/90-gpd-rules.hwdb

evdev:atkbd:dmi:bvn*:bvr*:bd*:svnGPD:pnG1619-01:pvr*
 KEYBOARD_KEY_a0=!mute

GPD Win Max 2021

Screen rotation

This device uses a portrait screen.

If you are using Xorg, create /etc/X11/xorg.conf.d/30-monitor.conf to rotate the screen:

Note: The Identifier may be different depending on your display driver of choice (either DSI-1 ^{(modesetting)} or DSI1 ^{(xf86-video-intel)})

/etc/X11/xorg.conf.d/30-monitor.conf

Section "Monitor"
	
  Identifier "DSI-1"
	
  Option     "Rotate" "right"
	
EndSection

To rotate the virtual console, add fbcon=rotate:1 to the Kernel parameters.

GPD Win Max 2

Keyboard

BIOS < 1.04 and kernel > 5.18.9: the keyboard IRQ, as specified in the BIOS, is incompatible with a change made in kernel 5.18.10 targeting AMD 6000 APUs.

Consequently, the keyboard will not work without either patching the kernel or applying a DSDT override.

Kernel patch:

kbd_irq.patch

IMU (Accelerometer + Gyro)

The IMU (Bosch BMI160) is incorrectly identified in the BIOS. A DKMS patch may be applied.

Alternatively, a DSDT override may be generated with the correct part number. The aformentioned keyboard fix and following IMU fix may be combined into a single DSDT override.

GPD Win Max 2 (2023)

Sleep/ Si0X

With the old BIOS, The GPD Win Max 2 2023 edition might have problems with sleep: It might wake up (instantaneously or after some time). It is now working on https://gitlab.freedesktop.org/drm/amd/-/issues/3073.

It's now fixed in the .38 BIOS.

IMU (Accelerometer + Gyro)

With the old BIOS, the IMU (Bosch BMI260) is incorrectly identified in the BIOS. It's named BMI0160:00 in ACPI table. It's now corrected in the .40 BIOS.

The package bmi260-dkms^AUR installs the correct kernel driver bmi260_i2c and the sensor works with that. (For low level testing, use /usr/lib/iio-sensor-proxy -v from package iio-sensor-proxy.)
Kernel modules bmi160_spi, bmi160_i2c and bmi160_core can be blacklisted to stop false autoload if not needed for some external device.

Known issues

GPD Win Max 2021 (Intel)

Deep sleep

Deep sleep is not working and there is no fix.

GPD Win Max 2

Fingerprint reader

The fingerprint reader (ChipSailing CS9711 @ USB 5.4) is, as of yet, unsupported.

USB autosuspend

On BIOS version v1.04, the USB controller may fail to enumerate devices that are newly plugged in after boot. This is due to a bug with USB suspend support and can be worked around by disabling autosuspend with the kernel parameter usbcore.autosuspend=-1.

GPD Win Max 2 (2023)

Fingerprint reader

The fingerprint reader (ChipSailing CS9711 @ USB 5.4) is, as of yet, unsupported.

Notes

GPD Win Max (2020) kernel requirement

The 2020 variant uses a different location for EDID that is not supported by Linux kernels prior to 5.18.

Linux kernel 5.18 or above is required for the screen to work.

BIOS updates

fwupd is not supported.

GPD provides BIOS updates via Windows executables in the following locations:

GPD Win Max: https://gpd.hk/gpdwinmaxfirmware
GPD Win Max 2021: https://gpd.hk/gpdwinmax2021firmwaredriver
GPD Win Max 2: https://gpd.hk/gpdwinmax2firmwareanddriver

See Windows PE for instructions on how to make a bootable Windows environment to apply the updates.
