|* get kernel in the archives|
- look into flash-kernel package
<persia> It's the pile of scripts that hook into kernel postinst and put the kernel somewhere useful to boot. <persia> Interesting bits are ./flash-kernel and ./debian/flash-kernel-installer.postinst
- get meego integration package in the archives
- cleanup seeds (introduce new seed kubuntu-minimal and change dependencies to kubuntu-minimal: minimal, kubuntu-common: desktop-common kubuntu-minimal, kubuntu-mobile: kubuntu-minimal)
- pimp default settings
- get gles working with plasma-mobile (requires pvr drivers, see below)
Installing Kubuntu on n900
- Maemo5 pr1.3 installed
- MicroSD 8GB, at least, class 6 or better.
Download latest kubuntu-mobile image http://cdimage.ubuntu.com/kubuntu-mobile/daily-preinstalled/current/
- Create three partitions in the sd card
- 1. an ext3 partition using the most part of the disc
- 2. a swap partition
- 3. a small VFAT partition, so Maemo will not complain
- zcat the kubuntu-mobile image to the ext3 partition
zcat maverick-preinstalled-mobile-armel+omap.img.gz > /dev/sdc1
- fsck.ext3 the first partition (the one with the image on it)
- mount the first microsd partition where you want
- Enter it as chroot (you'll need to install qemu-arm-static and copy it from /usr/sbin to the partition)
Set a nameserver (e.g. echo "nameserver 18.104.22.168" >> /etc/resolv.conf)
Install the kubuntu mobile integration package from http://people.ubuntu.com/~apachelogger/mobile/n900-integration/
- Add a new user to the system and ensure the user is member of the admin and sudo groups
You should install openssh-server very much
- Ideally run sudo sync before unplugging to prevent issues
- The system is now ready to do an initial boot...
Enable the maemo.org extras-devel repository in n900, see http://wiki.maemo.org/Extras-devel
- Install the 'uboot-pr13' package with apt-get install or from 'System' section
- Verify it's installed by restarting your N900. A penguin should show up at startup and U-boot will be mentioned, let it time out and boot into Maemo.
- Place a uImage on the 3rd partition, when uboot times out it will look there for the uImage and if found look for the OS on partition 1 (i.e. exactly our setup).
- To boot to maemo execute 'run noloboot' in the uboot prompt
- To create a new uImage you will need the target kernel's vmlinuz file (usually to be found in /boot)
apt-get install uboot-mkimage mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Ubuntu" -d ./vmlinuz-* ./uImage
- Please note that you will have to use a full qualified file name for vmlinuz if you have more than one in the PWD
This method is based on the Meego instructions from http://meego.com/devices/handset/installing-meego-nokia-n900 and starts the Meego kernel.
- Get the Meego vmlinuz and raw.bz2 files
- bunzip the raw.bz2
- inspect it using sudo fdisk -l -u $FILENAME
- depending on the image you should see a couple of paritions, eventually you will need to try them
- to mount you need to specify the offset of the partition, which is calculated by multiplying the start point of the partition (as per fdisk) with 512. e.g. if it starts at 1, the offset will be 1*512=512
sudo mount -o loop,offset=512 -t auto meego-handset-armv7l-n900-1.1-mmcblk0p.raw /mnt/
- cp /mnt/boot/* /where/you/mounted/boot/
- cp /mnt/lib/modules/22.214.171.124-10.3-n900 /where/you/mounted/lib/modules/
- Additionally you want to replace your usb networking init with nokia-usb-networking from meego, as theirs is actually working
- Turn off device (and unplug USB)
- sudo flasher-3.5 -l -k meego-handset-armv7l-n900-*-vmlinuz-*-n900 -b
- plug in USB, device should autostart and kernel should be transfered
kubuntu mobile starts
for usb control you should make sure that the interface is up on mobile (modprobe g_nokia && ifconfig usb0 192.168.2.16 up) and follow http://wiki.meego.com/ARM/N900/Tips_and_Tricks/N900_USB_Networking mind that there is instructions are silly and that you need to make sure your udev does not contain cdc_ether but cdc_eem, after that you should be able to connect to the n900 (given that your own usb0 is also up, which should be handled by nm)
- It is recommended to edit the /etc/network/interfaces file on the mobile system to autoset usb0
auto usb0 iface usb0 inet static address 192.168.2.16 netmask 255.255.255.0 gateway 192.168.2.14 up route del default up route add default gw 192.168.2.14
- Note: using .16 is key, otherwise you will get SSH key clashes with maemo
- Since we are using .16 you will need to ensure the iptables route on your host machine also includes .16 (the meego setup only routes .15)
- rm /usr/bin/nepomuk*; rm /usr/bin/akonadi*
- Remove everything from /usr/share/autostart other than plasma-mobile
- Switch widget style from Oxygen to Plastique
- Switch off desktop effects
- Deactivate man-db updates:
debconf-set-selections <<EOF man-db man-db/auto-update boolean false EOF
- See packages the script below removes...
Meego uses btrfs, and since we are using a SD card it makes sense that you convert your ext3 to btrfs.
- fsck your ext3 partition
- sudo apt-get install btrfs-utils
- btrfs-convert $DEVICEID
- Once you are confident that everything went well you can remove the ext backup ext2_saved/image

For your convenience here is a script. Note that you need to change the 2 first consts to match your mount path and your git checkout path. The script will copy the most essential bits into your chroot, install ssh, shoot some pointless packages in the head, set rendering to raster, deactivate some fat autostart apps and leave you with creating a user named user (i.e. you just need to set the pw).

This script mounts your mobile install with dev, proc and sys mounted (necessary to upgrade via chroot). Just call it with the partition device as argument (e.g. ./script.sh /dev/sdc1)

Install packages from https://wiki.ubuntu.com/ARM/OMAP/Graphics then you can try the demo binaries as described on the same page. Note that Qt and probably also KDELibs and Plasma Mobile need rebuilding for GLES support.
