(First of all, thanks to xnt14 for allowing me to host the file and giving me a subdomain - I've moved my files to http://mohammadag.xceleo.org/public/ so you can find everything from me there, again, thanks)

Mouse working! See this Note: as I said above, the mouse pointer is broken, this does NOT seem to be a calibration but a kernel module one, or a broken X/xorg configuration file, the pointer works fine in Fedora 12 and Mer, so I'm assuming this is a cannonical modified X problem, need assistance on this as Ubuntu is be very unusable with a broken pointer.
How unusable is unusable? The pointer is flipped, so up is down, the top part of the screen moves the pointer to the bottom side, and the far ends of the screen cannot be tapped without pressure on the bottom side of the screen, again, I need help from someone who knows C to fix this.

Quick instructions, I'm not really into sfdisk so the instructions are based on gparted, if anyone feels the instructions could be better then please feel free to post what you want

1. Connect the N900 to a PC running linux (Live CDs/Virtual machines will suffice).
2. Use gparted to partition the N900's MicroSD card, the image is 2.3GBs uncompressed, so you'll need at least 2.5GBs to run Ubuntu (3GBs if you want extra space for /home or apps).
3. Unpack the tar.bz2 into the root of the partition, an easy way to do this would be to use file-roller, the defualt archive manager in Ubuntu.
4. Disconnect the N900 from your PC.
5. Open terminal, type ls /dev/mmcblk1* to see the partitions on your MicroSD.
Assuming your partition is /dev/mmcblk1p2..

Code:

mkdir -p /mnt/ubuntu && mount /dev/mmcblk1p2 /mnt/ubuntu

Code:

cp -r /lib/modules/* /mnt/ubuntu/lib/modules/
cp /lib/firmware/* /mnt/ubuntu/lib/firmware/
chroot /mnt/ubuntu /bin/bash
useradd -m <replace with your username here> (e.g useradd -m mohammad)
# fill in details as you wish.
visudo
# Edit the file and add your username to sudoers using visudo
# Example (replace my username with yours)
# # User privilege specification
# root	ALL=(ALL) ALL
# mohammad    ALL=(ALL) ALL

Code:

cp /usr/share/applications/gnome-terminal.desktop /home/mohammad/Desktop/

Code:

exit

6. Install bootmenu-n900 and add a bootmenu entry in /etc/bootmenu.d

Code:

vi /etc/bootmenu.d/ubuntu.ext.item
# Press I to enter input mode.
# Replace partition numbers with the ones on your device.

Code:

ITEM_NAME="Ubuntu 9.10 Karmic (external SD, partition 2)"
ITEM_ID="ubuntu"
ITEM_DEVICE="${EXT_CARD}p2"
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,rw"

Shutdown the N900, hold the U key to go into flashing mode then

Code:

flasher-3.5 --enable-rd-mode --set-rd-flags=no-omap-wd,no-lifeguard-reset,no-ext-wd

The need for R&D mode will be fixed soon, I didn't save how I did last time so I'll need to figure it out again.

Reboot, and pick Ubuntu in the bootmenu and gnome desktop should start.

Edit: oh and to get BT working (thanks giannoug)

Code:

echo "00:11:22:33:44:55" > /sys/devices/platform/hci_h4p/bdaddr; modprobe -r hci_h4p; modprobe hci_h4p
