Ubuntu-N8x0 2.2 - released - Page 15 - maemo.org

I have tried ubuntu... and it works nice... but three questions:

what's with that damn FN key? AFAIR it was working under Deblet, after logon (not on gdm screen)

How to get compiz working? It's launching, but I can see only windows created after compiz is running (the rest is "white")

Is there any progress with sound? Where's the problem with it?

Why every moment that I type

$ umount

it answers me with: "umount: cannot umount /media/mmc2: operation not permited"

Ok. I thoungh it was the permission, so, I entered as root.

So it returns with : "umount: cannot umount /media/mmc2: device or resource busy"

Does it means that I have to format it? If yes, witch filesystem should i use?

I'm a linux noob and beginner, so, take it easy,

Cheers

This is an updated version of the previous port of ubuntu that includes major base system changes. This version takes full advantage of the new sys-env package system witch will make installing ubuntu on the tablets 90% easier by automating the install prosess through apt. (Similar to Deblet's nit-env system)

Disclaimer:
I am not responsible for what you do to your tablet. Dispite the fact that this insallation method is faster/safer than the previous port, following theas instructions incorrectly could lead to a non-functional system leading to a reflash.

What's new:

*Bootstraping the base system is no longer needed (optional)
*Better/faster installation method with sys-env
*Slightly faster boot time
*Base rootstrap image is only 75mb in size (compressed)
*Automated installation/configuration prosess through apt

What works:

*Dsme
*Screen diming
*Hal
*Xserver-xorg
*Simple compiz visual effects (libgl-mesa-sw-x11)
*Compositing
*Power management
*keymapping
*Usbnet emergency talend
*Powersave
*Right click
*Wierless
*Bluetooth

What needs work:
*Sound
*Usplash (as a replacement for omap-fb-splash)

This installation prosess requires the following to be installed on your system:

*gnutar
*wget
*easyroot / rootsh / becomeroot
*e2fsprogs (installed by default in Diablo)

Installation:

Step 1 ~ partitioning your memory card

Assuming that you want to partition your internal memory card (mine is mmcblk0), as root run the following in a terminal; this will create a 312mb FAT32 partition, a 200mb swap partition, and the rest as LINUX83. (note: you might need to reboot after doing this)

Code:

umount /dev/mmcblk0p1
sfdisk -uM /dev/mmcblk0
,312,C
,200,S
,,L
,,

Step 2 ~ Formatting your partitions

As root, run the following, this will format your first partition in vfat, yoou second partition in swap, and your last partition in an ext3 format for your rootfs.

Code:

umount /dev/mmcblk0p1
mkdosfs /dev/mmcblk0p1
mkswap /dev/mmcblk0p2
mkfs.ext3 /dev/mmcblk0p3

Step 3 ~ Installing the base system

First, we need to create our target directory and mount our partition to extract the base system. You can run the following as root to do so. (note: ignore any errors that may come up - they're harmless)

Code:

mkdir -p /mnt/jaunty

insmod /mnt/initfs/lib/modules/`uname -r`/mbcache.ko
insmod /mnt/initfs/lib/modules/`uname -r`/ext2.ko
insmod /mnt/initfs/lib/modules/`uname -r`/jbd.ko
insmod /mnt/initfs/lib/modules/`uname -r`/ext3.ko

mount /dev/mmcblk0p3 /mnt/jaunty -o noatime

Next, we will cd into our target directory, wget -c the rootstrap image and, extract the base system. Run the following as root:

Code:

cd /mnt/jaunty

wget -c http://files.getdropbox.com/u/1183030/ubuntu_9.04_n8x0-2.2_rootfs.tgz

tar -zvxf ubuntu_9.04_n8x0-2.2_rootfs.tgz

rm -f ./ubuntu_9.04_n8x0-2.2_rootfs.tgz

Then, we need to mount any nessasary directorys, chroot into the extracted rootfs and, set a root password:

Code:

mount /proc /mnt/jaunty/proc
mount /sys /mnt/jaunty/sys
mount /dev /mnt/jaunty/dev
mount /dev/pts /mnt/jaunty/dev/pts
mount /tmp /mnt/jaunty/tmp

chroot /mnt/jaunty

passwd root

Last we need to install sys-env-* to finish the installation of the system, there are currently two options:

*sys-env-base - a verry minimal bootable preconfigured system with usbnet emergency talend, raw console on framebuffer, and ubuntu-rescue-menu, dsme, hal, and wireless

*sys-env-x - (installed on sys-env-base) a system with full blown X11 (xserver-xorg) and support for gnome, kde, e17, xfce4 and, lxde

(comming soon)-

*sys-env-ubuntu - a full-blown ubuntu-desktop gnome system with right-click support, software-rendered OpenGL, Gimp, FireFox3, Xarchiver, Adobe-Flashplayer 9, Compiz, Abiword, wifi-radar and, screen diminig.

*sys-env-kubuntu - a full blown kubuntu kde system with similar features that sys-env-ubuntu provides - with the exception of right-click support - sorry

*sys-env-xubuntu - a full-blown xubuntu XFCE4 desktop with similar features provided by sys-env-ubuntu but with the advantage of being lighter-weight

*sys-env-lxubuntu - a full-blown lxubuntu LXDE desktop with similar features provided by xubuntu but with the advantage of also being a light-weight environment.

*sys-env-e17 - a full-blown enlightenment e17 environment that's light weight and user-friendly on mobile devices.

Assuming you've chosen sys-env-x, run the following while chrooted in ubuntu. (note: this may take quite a while, so go grab some coffie

)

Code:

su root
export LC_ALL=C

apt-get install sys-env-x

apt-get clean

And you're done!!

To unmount the system run the following while still in the chroot:

Code:

umount /proc
umount /tmp
umount /dev/pts
umount /sys
exit
exit
fuser -m /mnt/jaunty -k
umount /mnt/jaunty/dev
umount /mnt/jaunty

Tweeking & costomising

This section is entirely optional and may verry depending on your installation setup.

Installing ubuntu-desktop:

Code:

apt-get install ubuntu-desktop tablet-gdm-autologin

Installing kubuntu-desktop:

Code:

apt-get install kubuntu-desktop tablet-kdm-autologin

Installing xubuntu-desktop:

Code:

apt-get install xubuntu-desktop tablet-gdm-autologin

Re-configuring /etc/fstab to your system setup. (note: this is based off of the partition setup provided at the top of this page)

Code:

rootfs  /       rootfs  defaults,errors=remount-ro,noatime,nodiratime   0	1
proc    /proc   proc    defaults        0       0
/dev/mtdblock4  /mnt/rootfs     jffs2 defaults  0       0
/dev/mmcblk0p2  swap  swap	defaults	0	0
/dev/mmcblk0p1 /media/mmc2	vfat defaults	0	0

For the umount issue, i would recommend rebooting the device or running the following to kill whatever process that may be using it:

Code:

fuser -m /media/mmc2 -k

As for the format process, use steps 1 and 2 under the installation section.

However, you may not be very successful with the ubuntu-n8x0 installation process as there are a _lot_ of broken/outdated packages. So you may have more success with this guide. Just make sure you read this post for new repository links while editing /etc/apt/sources.list in ubuntu during the install process.

Sorry, but, after i type the fuser comand ($ fuser -m /media/mmc2 -k)
it returns with the same problem. Should I reflash my tablet?

Thanks

Rebooting the device doesn't resolve the issue?

but, at the command prompt in the chroot, how do I start ubuntu?

i tried with gdm and startx but nothing happens
if I do a "ps -fea | grep 'gdm' " I get:
