## 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

    diff --git a/drivers/acpi/resource.c b/drivers/acpi/resource.c
    index 510cdec375c4..c2d494784425 100644

     	for (i = 0; i < ARRAY_SIZE(skip_override_table); i++) {
     		const struct irq_override_cmp *entry = &skip_override_table[i];

DSDT changes:

    kbd_dsdt.diff

    ---
    >                     IRQ (Level, ActiveLow, Exclusive, )

#### 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.

DSDT changes:

    imu_dsdt.diff

## 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`.

## 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.
