Quick installation of ubuntu on the toshiba AC100 netbook

This is pretty quick since we don't push android out, repartition etc. The goal is just to have an ubuntu system fast.

The first thing to do is to start the netbook, and hook it to your main computer with a USB cable. A notification will appear in the upper left part of the screen, where you'll be able to enable the file sharing.

Once file sharing is enabled, the main computer's "dmesg|tail" will show it detected a /dev/sdX (it was /dev/sdc in my case... YMMV). This is the partition we will put ubuntu on. First thing : "mkfs.ext3 /dev/sdX" -- this will format the partition, just complaining that we didn't do several partitions. Second thing, mount that disk, something like "mount /dev/sdX /mnt/disk" could do the trick. Third thing, grab Ubuntu5.tar.lzma from http://kotelett.no/ac100/phh/, then just "tar xavf Ubuntu5.tar.lzma -C /mnt/disk".

At that point there is an ubuntu system on the device, but it's not bootable as-is. This is where we need nvidia : go to http://tegradeveloper.nvidia.com/tegra/downloads, and get the linux for tegra support pack ; this is an .run file which you'll just need to decompress (by running it). Once you have it, "cd linux4tegra/nvflash" and get boot.img from http://husson.hd.free.fr/boot.img. You now have all you need on the main computer. Let's turn to the device : shut it down. Really down, not sleeping. Then power it on while holding ctrl+esc down -- the screen stays blank, but it's normal. The device is in flash mode, where the following command should be run on your main computer :
LD_LIBRARY_PATH=. ./nvflash --wait --bl ../prebuilt/fastboot.stock.bin --download 5  /path/to/boot.img --go
This command should end by telling you all went well. Shut the device down.

Now hold the home key down while you power the device on : it will print a text saying quite few things ; the gist of it is that pressing the 1 key will boot ubuntu. Yes, you'll have to do that everytime you don't want android. You can have ubuntu by default by using '6' instead of '5' in the previous command, but it will break android.

You should soon get in front of the typical ubuntu setup assistant, which will ask you your name, where you live etc. As final setup, you could :
- edit /etc/X11/xorg.conf, so your alt+gr key gets recognized properly ;
- fetch the lid-switch-daemon from http://mt4.es/ac100/lid-switch/, install it in /usr/sbin, and edit /etc/rc.local so it is launched with "-d -s" -- it will put the box to sleep when you close the lid ;
- while you're editing /etc/rc.local, replace /button by /usr/sbin/button.

This should make a honest ubuntu system.
