## Specifications

There are two models differentiated by processor, memory speed and capacity, storage capacity, Thunderbolt support, and wireless network hardware.

### 1195G7

- Display: 8" 1920x1200
- CPU: Intel Core i7-1195G7
- RAM: 16GB LPDDR4x 3733

- CPU: Intel Pentium Silver N6000
- RAM: 8GB LPDDR4x 2933

## Firmware

fwupd is not supported on this device. GPD provides firmware updates via Windows executables.

See https://gpd.hk/gpdpocket3firmware for the files and Windows PE for instructions on how to make a bootable Windows environment to apply the updates.

## Audio

Using `snd-intel-dspcfg` (legacy) instead of `sof-firmware` enables sound on the 1195G7 model.

    /etc/modprobe.d/gpdp3.conf

    options snd-intel-dspcfg dsp_driver=1

The N6000 model utilizes ESSX8326 sound hardware and drivers are usually provided by `sof-firmware`. Neither speakers nor headphone audio work at this time. There is an open bug report on the sof project GitHub requesting help specifically for the Pocket 3. The es8xxx series sound devices have a history of problems with Linux and there is a general lack of interest in solving them. A patch was made on the github's issue page that seems to work and need testing.

See https://github.com/thesofproject/linux/issues/3393

## Wireless

This section is being considered for removal.

Reason: This should probable be removed once linux-lts is 5.16. (Discuss in Talk:GPD Pocket 3)

As of kernel `5.16.0` and `linux-firmware, version 20220411.705f19a-1` WiFi works with no additional configuration.

## Display

The Pocket 3's display is designed for portrait devices and is rotated by 90 degrees counter-clockwise by default. This can be solved by adding the following kernel parameters:

    fbcon=rotate:1 video=DSI-1:panel_orientation=right_side_up

The first parameter (`fbcon`) will fix console rotation. The second (`video`) rotates other graphical elements including Plymouth, Wayland, and GDM to the correct, landscape orientation.

### Backlight

Control is provided by installing xorg-xbacklight. Keyboard shortcuts can be configured with xbindkeys.

### Screen Tearing

Due to the display being designed for portrait devices, the device experiences vertical screen tearing.

This can be solved by ensuring xf86-video-intel is installed and following the instructions in Intel graphics#Tearing.

### Touchscreen and Digitizer

Note: Stylus comparability is a work in progress. See Talk:GPD Pocket 3 for more information.

Install xf86-input-wacom.

The touchscreen and digitizer matrix are in portrait mode and have to be rotated 90 degrees clockwise. Furthermore, the stylus pen behaves oddly under libinput, so we can force the wacom driver and get reasonable usability. This can be corrected for all touch and pen interfaces at once with the following configuration for X:

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

    Section "InputClass"
      Identifier    "calibration"
      Driver        "wacom"
      MatchProduct  "GXTP7380"
      Option        "TransformationMatrix" "0 1 0 -1 0 1 0 0 1"
      Option        "Button2" "3"
    EndSection

See https://github.com/defencore/gpd-pocket-3-linux

### Automatic Rotation

xrandr and xinput rotation can be automated with 2in1screen.

## Webcam

The Alcor Micro Corp. webcam is a USB 2.0 device with a maximum resolution of 1600x1200 at 30fps. It does not support any 16:10 resolutions to match the screen aspect ratio.

## Fingerprint Sensor

The FocalTech FTE3600 is an SPI fingerprint reading device. It currently has no Linux driver.

See https://gitlab.freedesktop.org/libfprint/wiki/-/issues/47

## Function keys

Key | Visible?1 | Marked?2 | Effect
--- | --- | --- | ---
`Fn+Printsc` | Yes | Yes | `XF86MonBrightnessDown`
`Fn+Insert` | Yes | Yes | `XF86MonBrightnessUp`
`Fn+[` | Yes | Yes | `XF86AudioMute`
`Fn+]` | Yes | Yes | `XF86AudioLowerVolume`
`Fn+\` | Yes | Yes | `XF86AudioRaiseVolume`
`Fn+-` | Yes | Yes | `Menu`
`Fn+=` | No | Yes | Fan control3
`Fn+space` | No | Yes | Enables/disables keyboard backlight4

1. The key is visible to `xev` and similar tools
2. The physical key has a symbol on it, which describes its function
3. toggles between low and high speed, firmware controlled, not configurable
4. toggles between on and off, firmware controlled, not configurable

## Suspend

As per GPD's announcement, suspend level S3 is not currently functioning correctly. S2 suspend can be forced by adding the `mem_sleep_default=s2idle` kernel parameter.

Warning: By default the device is set to suspend when the lid is closed, the display will not recover until reboot. Video will work on an external monitor but it could be majorly inconvenient without access to one. It is recommended to disable suspend on lid closure without the S2 fix in place.

Set `HandleLidSwitch=ignore` for logind, as explained in Power management#ACPI events.

## Thunderbolt

Thunderbolt works out of the box on the 1195G7 model (not available on the N6000 model). See Thunderbolt for general information and External GPU for enhanced graphics via an external GPU enclosure.

## Additional Features

### BIOS Reset

The small hole on the rear of the device between the hinge and the module slot contains a BIOS factory reset button.

### Optional Mounting

The left and right side of the device each have a 2.5mm threaded hole by the hinge. This hole can be used as physical mount for customization.

### Optional KVM Module

Video capture functions as a standard v4l device and can be opened with software such as obs or via command line with FFmpeg.

When a USB cable is plugged from the module into another computer, the Pocket 3's keyboard, touchpad, and mouse buttons will switch to functioning as input for the connected machine without drivers or configuration.
