Talk:Ubuntu Lucid on OLPC XO
It works!! Just following the instructions, more or less, gave me a running system.
A few details:
There need to be a few more "sudo" commands. I am not sure if it is needed for depmod, but it is certainly needed for the following "ln".
depmod 2.6.31_xo1-xxxxxxx
ln -s /lib/firmware/libertas/usb8388_v9.bin /lib/firmware/usb8388.bin
I used qemu, using the USB device as HDA, and with additional memory -- when I tried to install everything using 256MB of RAM, the install would always crash. Here are my two qemu commands, the first one for booting from the cdrom (to be done initially), the second for booting from the hard disk. Pay attention to the stuff in parentheses -- you really do need to check which device your usb drive is on (I did it with
ls -l /dev/disk/by-id/
you may have other methods), and the tftp option was needed to load the develop.sig, which I had on a different device:
sudo qemu -hda /dev/sdc (check) -cdrom ubuntu-10.04-beta2-desktop-i386.iso -m 512 -boot d -net nic -net user sudo qemu -hda /dev/sdc (check) -m 512 -boot c -net nic -net user(,tftp=/home/user/olpc)
to use these, remove the "(check)" (only after checking! :-), and, if you need to transfer files from the host, remove the parentheses around the tftp option, e.g. -net user,tftp=/home/foo/xyz, where the path indicates the root of the tree accessible with the tftp command. Once you have booted ubuntu, you also need to
sudo apt-get install tftp
for this to work.
Finally, make sure your device really does have a label OLPCRoot. I don't think that is emphasized enough in the instructions.
With these considerations, the install actually went very smoothly. I am just afraid my 256MB OLPC may be too small for ubuntu lucid. Also, the wireless network doesn't seem to connect automatically (yet).
I hope this helps others!
