[Acer Iconia A500] Worldblender:
Premade Linux images

I finally have managed to create a premade image to make the installation process easier for other people, especially for those who don't want to go through the hassle of compiling software. Every image I make can be found at https://drive.google.com/drive/folders/1pMqaS5GaM6N9TAKlNGQZWCG8UTiRn4pK?usp=sharing.

For most images:

Kernel version: 5.15.0-rc4

Includes all compiled kernel modules from postmarketOS builds, plus nonfree firmware enabled.

The postmarketOS splash screen will appear, although the underlying OS differs based the image used.

Images available:

Ubuntu MATE 22.04 (ubuntu-mate-22.04.-desktop-armhf+acer-picasso.img.xz) (size: 2.0 GiB):

Based on 'ubuntu-mate-22.04-desktop-armhf+raspi.img.xz', available from https://ubuntu-mate.org/ports/raspberry-pi/

Underlying OS is Ubuntu 22.04, which is supported for 5 years until April 2027. However, Ubuntu MATE officially has support only until April 2025.

Kernel version: 6.6.7-r0

Requires at least an 8 GB or greater size microSD card (the image is 7.0 GiB decompressed).

The setup screen will open upon the first successful boot, where a username and password have to be set. If errors are encountered during the install, then it is also possible to chroot into this root filessytem to create an account with 'adduser' or 'useradd'. Adding this user to at least the groups 'adm' and 'sudo' is strongly recommended, to be able to perform administrative tasks. QEMU user emulation may be required to complete this, see https://wiki.debian.org/QemuUserEmulation for more information. If nothing is done after this crash happens, the system may become unusable except for the guest account.

Most extra packages for the Raspberry Pi family of computers have been removed, including the kernels.

The PPA at https://launchpad.net/~grate-driver/+archive/ubuntu/ppa is pre-configured to be accessed. Most packages from this repository, including the opentegra driver, come preinstalled. They currently are enough to get 2D acceleration working, but not for 3D acceleration.

All packages have been updated as of 12/22/2023.

Ubuntu MATE 20.04.1 (ubuntu-mate-20.04.1-desktop-armhf+acer-picasso.img.xz) (size: 1.3 GiB):

Based on 'ubuntu-mate-20.04.1-desktop-armhf+raspi.img.xz', available from https://ubuntu-mate.org/ports/raspberry-pi/

Underlying OS is Ubuntu 20.04.1, which is supported for 5 years until April 2025. However, Ubuntu MATE officially has support only until April 2023.

Requires at least an 8 GB or greater size microSD card (the image is 5.6 GiB decompressed).

The setup screen will open upon the first successful boot, where a username and password have to be set. If errors are encountered during the install, re-imaging may be required. There are several workarounds in the next point. If nothing is done after this crash happens, the system may become unusable except for the guest account.

Either: Use Ctrl+Alt+T to open a terminal for the user 'oem'. The password is set to 'ubuntu'. Do any administrative tasks as needed. | It is also possible to chroot into this root filessytem to gain root access, but QEMU user emulation may be required to do this, see https://wiki.debian.org/QemuUserEmulation for more information.

In administrative mode:

adduser [your chosen username]; usermod -aG adm,dialout,cdrom,floppy,sudo,audio,video,plugdev,users [your chosen username]

Most extra packages for the Raspberry Pi family of computers have been removed, including the kernels. The Snap Daemon (that allows installing snap files) is disabled to increase performance.

Additional programs installed: curl, links, mc, netsurf-gtk, tmux, vim

The battery icon in MATE cannot be enabled graphically, as the preferences window has been patched to permanently hide such an option (as the Raspberry Pis lack native battery support); instead run the command

gsettings set org.mate.power-manager icon-policy 'always'

to manually enable it.

The PPA at https://launchpad.net/~grate-driver/+archive/ubuntu/ppa is pre-configured to be accessed. Most packages from this repository, including the opentegra driver, come preinstalled. They currently are enough to get 2D acceleration working, but not for 3D acceleration.

Except for what has been mentioned above, any packages shipped may have to be updated once an internet connection is established.

Use any image writing program with these images. If such a program does not support XZ compression, the image needs to be extracted instead, and that has to be used.

I hope the images will proves useful to some people. Let me know if any issue pops up during usage of this image!
