Porting Ubuntu 16.04 to Toshiba AC100

WARNING: This is experimental, slipstreamed Xubuntu desktop. Many things don't work yet. I'm not responsible for any stability and functionality issues.

It is strongly recommended to use virtual machine/secondary operating system to build root filesystem.

Changes I've applied

Compared to my Ubuntu 14.04 port

• All upstream patches and changes
• U-boot and upstream Linux 3.16 kernel
• XFCE instead of GNOME Flashback

Many things are not ported yet, such as keybinding, swap partition or themes.

Known issues

• No proprietary graphics drivers - therefore no HDMI output, HW acceleration, or webcam support
• No sound yet
• Cannot turn off device (please shutdown system, then hold power button)
• Random kernel panics

How to build

1. Make sure you're running Ubuntu 16.04
2. Install debootstrap and qemu-user-static packages
3. Download this repository to your PC
4. As root, execute ./build.sh

Tip: You can use time utility to display how much time the process took (less than 1 hour in most cases), or append 2>&1 | tee log.txt to save logs. Output file is called rootfs.tgz.

Prepare device

1. Install proprietary nvflash utility (can be found here).
2. Connect AC100 to PC, press and hold Ctrl+Esc+Power.
3. Execute nvflash --bl sos-uboot-r5-2013-09-23.bin --go to boot into recovery mode

Install Ubuntu

1. Copy two files to FAT32-formatted flash memory
   • installer.sh
   • rootfs.tar.xz
2. If you don't have U-boot installed, run ./switch-to-uboot
3. Mount USB device: mount -t vfat /dev/sda1 /mnt
4. Start installer and follow instructions: sh /mnt/installer.sh
5. Reboot device, wait 1-2 minutes to see setup wizard and finish installation.
