sry if it is late. i got no mail for this threat anymore.

/lib/modules has subdirectories. each of them contains parts of specific kernel. any kernel that as parts of it compiled as separate modules you need one such directory or that parts of the kernel are missing.
so if changed the kernel you will need the modules for the kernel.

/lib/firmware is different. it contains parts that depend on the devices. well, for you use the device via drivers it is also closely connected with the kernel. but in most cases you won't have to change the firmware if you change a kernel and vice versa.

so if it is one of the two that causes you the trouble, it is rather the first.

Re: [WIP] Ubuntu 9.10 on the N900

i want to install ubuntu on my n900 but i dont want to install it on my memory card cus its only 1gb capacity so if anyone knows a way to install to the phone memory with multiboot too just post .. tnks in advance. :)

It's just easy... Just change EXT_CARD into INT_CARD on the item file of multiboot(Well that's what I did on bootmenu)...

Harder part is to partition your EMMC.. Don't ask me for a tutorial I'm bad at doing it. Just search this forum there's a bunch of tutorials on repartitioning EMMC with gparted or fdisk.

Re: [WIP] Ubuntu 9.10 on the N900

Has this been abandoned?

thats actualy straight forward. only boot into a different disk first. the easiest way(least effort) is to boot into a ramdisk. and do what you want to your disk from there.

(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

I TRIED ALL THIS, but unfortunately, it seems that there is no Kernel to boot the Ubuntu. Pls kindly specify how to flash the kernel. I entered into R&D mode, but nothing happened.

Re: [WIP] Ubuntu 9.10 on the N900

i repeat.
1. watchdogsupport is the key to get rid of r&dor leave it on
2. ubuntu uses a different "arch" than debian and for that matter maemo. (to simplify even more: it speaks a different languague, ) so you need a kernel that has support for this. maemo kernel hasn't. powerkernel has. but it fails.
3. mousesupport is actually touchscreensupport and it is the tsc2005 driver you need. as it is part of the kernel you need one for the particular kernel you use and nothing else.
4. i said it before: it makes no sense to use a maemo kernel. a linux( != maemo) kernel works best(something recent). so go and grab a 2.6.37 linux kernel put everything you need in and you are mostly good.
5. if you want to keep your maemo kernel your best bet is the powerkernel. otherwise you do not want to flash a linux kernel for maemo needs a maemo kernel and won't run with a linux kernel. (powerkernel is something inbetween)so you either kexec into linux from maemo or have a meamo kernel to boot maemo and a linux kernel to boot linux.

Maybe it is because you have to handle watchdog. It's just an idea because that is a big problem if you try to run debian on the n900.
If "no-ext-wd" means "no external watchdog" than I'm right and you can go here under "Configure Base System" and look if you can use this solution for handling watchdog. ;)

Re: [WIP] Ubuntu 9.10 on the N900

Is it possible to use the usb keyboards etc on Ubuntu running on the nokia n900

As Ubuntu and Maemo are both linux platforms ??

Re: [WIP] Ubuntu 9.10 on the N900

hello,

i got 9.10 running on my n900(stock pr1.3),but i can't get wlan to work. It's not installed at all. The other problem is what i'm having, i can't shut it down, unless i take the battery out. can someone help me please? I followed these instructions.

Did you get 10.10 to work with keyboard and mouse support btw?
