At the moment no BIOS update is required to run Ubuntu respin iso. You can run any BIOS you want and you probably won't notice big differences. Different BIOS have however different features enabled. Check BIOS section here
Click here for the Docker building section
To respin an existing Ubuntu ISO, you will need to use a Linux machine with squashfs-tools and xorriso installed (e.g. sudo apt install -y squashfs-tools xorriso) and a working internet connection and at least 10GB of free storage space.
The first step is to clone this repo:
git clone https://github.com/stockmind/gpd-pocket-ubuntu-respin/
cd gpd-pocket-ubuntu-respin/
Install all the required packages:
sudo apt install -y git wget genisoimage bc squashfs-tools xorriso
Install all the required packages:
sudo pacman -S git wget cdrkit bc libisoburn squashfs-tools dosfstools
Download your favourite distribution ISO and copy it in this repository cloned folder.
- Running
./build.shin the terminal will download the most recent kernel automatically.
Kernel suggested is the one with patches from Hans De Goede. You can find his repository here: Hans De Goede Kernel Repository
sudo apt-get install build-essential git libncurses5-dev libssl-dev libelf-dev
git clone https://github.com/jwrdegoede/linux-sunxi.git
If you have already donwloaded the repository, you can update it with latest commits issuing:
git fetch origin
git reset --hard origin/master
Then proceed with building:
cd linux-sunxi/
sed -i "s|CONFIG_INTEL_ATOMISP=y|CONFIG_INTEL_ATOMISP=n|" .config # Fix audio crackling
make clean
make -j `getconf _NPROCESSORS_ONLN` deb-pkg LOCALVERSION=-custom
You can find the generated kernel .deb files in the parent folder where linux-sunxi repository have been cloned.
Compress all the .deb files generated into a zip named "gpd-pocket-kernel-files.zip" and put it in the root folder of this repository.
Run ./build.sh script as specified for your desired distro. If you built your own kernel, the build script wiill extract the kernels you zipped and install during respin.
- Build Xorg ISO (Ubuntu Unity, Linux Mint, XFCE, KDE) running this:
./build.sh <iso filename>
- Build Gnome based ISO (Ubuntu Gnome, Kali Linux, Gnome based distro) running this:
./build.sh <iso filename> gnome
- Build Xorg ISO (Ubuntu Unity, Linux Mint, XFCE, KDE) running this:
PATH=/usr/sbin:/sbin:/bin:$PATH ./build.sh <iso filename>
- Build Gnome based ISO (Ubuntu Gnome, Kali Linux, Elementary OS, Gnome based distro) running this:
PATH=/usr/sbin:/sbin:/bin:$PATH ./build.sh <iso filename> gnome
Gnome desktop environment and derivate (Pantheon of Elementary OS) use a different name convention for monitors. The default Xorg configuration won't work and a custom configuration must be used to get everything to work. That's the reason of the "gnome" argument for update and build script.
I sugget Etcher to write ISO on usb flash drives. It's fast, reliable and multi-platform.
Boot system using one time boot menu: Press during GPD logo Fn + F7 keys.
Don't boot your USB from a USB Type C adapter or USB Type C drive as it wouldn't work until USB Type C data is supported by kernel.
These commands should be run after the first boot. There is an update script that will do it automatically, or you can run the necessary commands manually.
You can run my update script to update your installation and grub options, and to setup everything after an install or after a Desktop Environment change.
sudo apt-get install -y git
git clone https://github.com/stockmind/gpd-pocket-ubuntu-respin.git
cd gpd-pocket-ubuntu-respin/
chmod +x update.sh
- Unity, KDE, XFCE as Desktop Environment:
sudo ./update.sh
- GNOME, Pantheon (Elementary OS) as Desktop Environment:
sudo ./update.sh gnome

Update kernel to latest version issuing the following command:
sudo ./update-kernel.sh
A kernel update is always recommended.
Here is an already respinned Ubuntu ISO for GPD Pocket

Latest versions are available here: http://www.gpd.hk/news.asp?id=1519&selectclassid=002002
Second version - Chinese Mirror - My mirror
First version (Working iso, GPD one uploaded on indiegogo was corrupt)
-
Customary BIOS: Original BIOS shipped with first batch of production.
-
2017/06/28 BIOS for Ubuntu: BIOS released for Ubuntu beta firmware.
Changelog: 1 - All settings are enabled so you can customize all the option of the BIOS. 2 - Should have the fan working on boot -
2017/07/05 BIOS: Second BIOS officially released, on this BIOS fan will turn on while charging when device is powered off.
Changelog (Google translate): 1 - boot on the fan ( Probably to support GPD official Ubuntu firmware that doesn't seems to handle fan directly ) 2 - improve the DPTF temperature, before the limit for the CPU temperature higher than 85 degrees or the battery temperature is higher than 58 degrees will CPU down. -
Changelog (Google translate) 1 - This BIOS has changed the boot logic. In the previous BIOS device will boot only with a charge of 10 to 17%, now you only need at least some charge to boot.
- Download the latest BIOS
- Install the flashing utility
sudo apt install flashrom
- Use
cdto enter the directory where you downloaded the BIOS - Backup the current BIOS
sudo flashrom -p internal -r backup.bin
- Flash the new BIOS
sudo flashrom -p internal -w Rom_8MB_Tablet.bin
- Reboot Your Computer
Notes: You may need to restore BIOS setting to their default in order to get everything running smoothly.
To get charging working correctly a different Power Delivery 2.0 charger may be required, based on kernel used, otherwise charging will be slow and will just keep device charge stable when in use. i.e. it will not drain battery as it may happen on old or generic kernels, but won't charge device more than when connected to power.
Follow some data recorded with several chargers and systems regarding the charge delivered and perceived by the system:
| Charger | System | Volts (Avg.) | Ampere (Avg.) |
|---|---|---|---|
| Stock GPD charger | 4.12-rc2+ kernel (GPD official firmware) | 4.70v | 2.5a |
| Aukey charger | 4.12-rc2+ kernel (GPD official firmware) | 4.70v | 2.5a |
| Stock GPD charger | 4.12-rc7 kernel (HansDeGoede kernel) | 4.89v | 0.5a * |
| Aukey charger | 4.12-rc7 kernel (HansDeGoede kernel) | 4.89v | 2a |
| Stock GPD charger | 4.13-rc3 kernel (HansDeGoede kernel) | 11.8v | 1.5a |
| Aukey charger | 4.13-rc3 kernel (HansDeGoede kernel) | 9.20v | 0.5a ** |
| Stock GPD charger | 4.13-rc5 kernel (HansDeGoede kernel) | 11.8v | 1.3a |
| Aukey charger | 4.13-rc5 kernel (HansDeGoede kernel) | 9.0v | 1.4a |
| Stock GPD charger | Windows 10 | 11.70v | 1.7a |
| Aukey charger | Windows 10 | 8.90v | 2a |
* Charging will not drain battery but won't charge device more than when connected to power
** Charging will be slow
Any kernel after 4.13-rc5 (From Hans de Goede repository) should be fine for full-speed charging! Mainline kernel 4.14 or later should be fine.
Ampere delivered may vary depending on the remaining battery charge.
The tests have been performed using this Jokitech USB-C Power Meter Tester Multimeter

Google Chrome: Works out of the box with multitouch gestures. No configuration needed.
-
Firefox: Bundled builds of Firefox in Ubuntu and derivates doesn't support touch gestures by default. You need a build with cairo-gtk3 enabled, you can check it in "about:buildconfig", if it's missing touch will probably won't work in your build. You can get a build with that module enabled on Firefox official site or here. Install it and add
MOZ_USE_XINPUT2=1in /etc/environment (if not already present) or run Firefox with
env MOZ_USE_XINPUT2=1 firefoxIf it still doesn't work after a reboot try to add this boolean key in "about:config": browser.tabs.remote.force-enable and set it to true.
-
Touchegg: This enable some multitouch gesture on touchscreen and you can use it like a touchpad. It works only with non-libinput backend. Works good on XFCE. Won't work with GNOME, Elementary OS. Issue Possible fix for GNOME, Elementary OS You can install it by issuing "sudo apt-get install touchegg" and use, or try the gpdpocket-touchegg-config package by nexus511
-
Libinput-gestures: This enable multitouch gestures. Works on GNOME, Unity, Elementary OS and Desktop Environment that use libinput as default. It supports Xorg and partially Wayland.
You can monitor frequencies of cpu issuing:
cat /sys/bus/cpu/devices/cpu*/cpufreq/scaling_cur_freq
You can respin iso and build kernels on a Docker environment easily. This build system will likely work on any x86 Docker supported platform. Tested and working on Linux and MacOS, builds on Windows not tested yet.
You just need to build the Docker image, or download it from Docker Hub, and follow the steps below.
docker pull stockmind/gpd-pocket-ubuntu-respin
Clone repository and run the following script to build the docker image
./docker-build-image.sh
Once the image is ready you can choose from the following steps:
To respin an ISO you need to place desired ISO in origin/ folder of this repository then run:
a. Distro based on Unity, KDE, XFCE as Desktop Environment:
./docker-respin.sh <iso-file-name-without-path>
b. Distro based on GNOME, Pantheon (Elementary OS) as Desktop Environment:
./docker-respin.sh <iso-file-name-without-path> gnome
Example:
./docker-respin.sh ubuntu-17.04-desktop-amd64.iso
Or:
./docker-respin.sh ubuntu-GNOME-17.04-desktop-amd64.iso gnome
Let it run, it will take from 10 to 30 minutes based on your internet connection and system speed.
Once done you will find output ISO in destination/ folder of this repository named as gpdpocket-<build-date>-<iso-file-name>.iso.
To build latest kernel you just need to run the following script:
./docker-build-kernel.sh
Let it run, it will take a while.
When it's done you can find the kernel zipped in destination/ folder of this repository.
If you made a mistake and want to stop the running containers in background for respinning or building you can use the stop script:
./docker-stop.sh
Press the power button to let the desktop load and look at issues below.
Brightness management is currently broken on a Live environment. You must install system on your drive to get it working.
Some sort of Unity daemon or watcher seems to read bad values from battery or charge and put system on sleep when charger is plugged in. This seems to happen also on boot of Live USB. Press any key or power button to wake. It only happens on Unity as far as i know.
Try to burn the image on a smaller usb device or try another image.
I sugget Etcher to write ISO on usb flash drives. It's fast, reliable and multi-platform.
Check that the correct sound output device is selected in System Settings. It should be "Speakers: chtrt5645" for device speakers and "Headphones: chtrt5645" for the audio jack output.
Check your system displays settings and move your displays until they are not overlapping each others.
Disable DPTF in BIOS (Unlocked BIOS might be required), that's what freezes the system before it reaches the hardcoded factory limit of 90 degree.
Audio jack may get disconnected on some headsets when volume is set over 70-80%. Windows does't have this problem with official GPD audio drivers. Windows have the same problem only when you using unofficial audio drivers (only one accept way is update audio driver over device manager). This doesn't seems to happen on tiny headphones. When this happen audio start to have a crackling noise again. To fix this you should restart pulseaudio and audio player.
To restart pulseaudio issue the following command
pulseaudio --kill && pulseaudio --start
or
pulseaudio -k
Video of the problem by Petr Matula @petrmatula (enable subtitles!)
Chrome doens't seems to behave great with the i915 intel driver, a workaround for the glitches or flickering while scrolling pages or seeing video is to set "GPU Rasterization" to "Force-Enabled for all layers". Quick link: chrome://flags/#enable-gpu-rasterization
The scaling ratio is set to 2 to be able to read on the screen but it sure takes of a lot of space out of the FullHD screen.
Things will be more aliased and have better edge but take more space on screen.
To restore to native pixel resolution you have to edit the scale configuration:
sudo nano /etc/X11/Xsession.d/90-scale
You have to edit all the values to their default:
gsettings set com.ubuntu.user-interface scale-factor "{'DSI-1': 8, 'DSI1': 8}" // Unity
gsettings set org.gnome.desktop.interface scaling-factor 1 // Gnome 3
gsettings set org.gnome.desktop.interface text-scaling-factor 1 // Gnome 3
gsettings set org.cinnamon.desktop.interface scaling-factor 1 // Cinnamon
gsettings set org.cinnamon.desktop.interface text-scaling-factor 1 // Cinnamon
This will affect all the different desktop environments. This might require a log-out, log-in, or reboot to take effect. Restarting the display manager service will also work. This way you can still read fine (if you have good 👀 ) and have all your pixels back.
Sometimes it may happen that rotation of touch or display is wrong due to several factor, particularly on GNOME or derived Desktop Environments. You can fix this simply selecting with mouse the GPD Screen Rotation icon on the tray bar ( 
) and clicking on the desired rotation on menu.
Ex. If your display is rotated in landscape correctly but touchscreen is not aligned, you can select "Rotate landscape" to fix this. The opposite is also valid. The script will do it's best to compensate the alignment problems that may happen.
You can try to use the "Reset touchscreen" option from the GPD Screen Rotation icon on your tray bar ( ). It will ask for your password. Wait for 5 seconds than retry to use touchscreen. If problem persist try to put system in sleep for a bit or reboot your device.
In some system it may happen that tray icon won't show at boot. Try to run in a terminal
gpdscreen-indicator
If it works add "gpdscreen-indicator" command to your system "Startup Application" utility to run it at boot.
To report a problem clone the repo, run "problem-reporting.sh" script and attach the output to your github issue. This will help debugging.
sudo ./problem-reporting.sh
