There is a 14 weeks old snapshot of gnome-shell in the karmic repositories.
You can try it by simoky installing the gnome-shell packaged vis asynaptic or with the command:
sudo apt-get install gnome-shell
But If you want an updated version, you can do the following:

1-Install the unofficial gnome-shell ppa repository: ppa:vperetokin/unofficial-gnome-shell
You can do that with the command:
sudo add-apt-repository ppa:vperetokin/unofficial-gnome-shell

2-Update your sources, and then your packages either via synaptic or with the commands:
sudo apt-get update
sudo apt-get upgrade

3-Install gnome-shell package:
sudo apt-get install gnome-shell

OK, it’s installed, now in orden to use it:

1-Compiz (Desktop Efects) should be disabled firts, so dissabke it from the Menu:
System>Preferences>Appearances
Then go to the Visual Efects tab and select None.

2-You can now start it at any time with the command:
gnome-shell replace &

OK, now is beginig to be possible to sync your music from Ubuntu to your iPhone, thanks to the work of marcan and many others.

Disclaimer: This is very Alfa software, I didn’t invented any of the things I’m writing about, I just adpated the marcan instructions in the way they worked for me, to my personal systems, wich I’m sure many are using: Ubuntu Karmic Koala 9.10 and iPhone 3G with OS 3.1.2, by the way you need to have some music synced by iTunes before you can start.
Don’t cry if your iPhone melts:

1- update your system, either via synaptic or with

sudo apt-get update

sudo apt-get upgrade

2- Add the PPA repository with the needed packages :

deb http://ppa.launchpad.net/jonabeck/ppa/ubuntu karmic main

Either adding it as root to your /etc/apt/sources.list file

Or with the GUI “Software sources”

Then add the key for the repo with this command:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com F0876AC9

And update again with:

sudo apt-get update

3- Install the packages required for compilation, and the already packaged libraries:

sudo apt-get install git-core cmake autoconf libtool libglib2.0-dev intltool gtk-doc-tools libsqlite3-dev libxml2-dev  libiphone-dev libplist1 libusb-1.0-0 libusb-1.0-0-dev libusbmux0 libusbmux-dev ifuse libiphone0 libplist0 libplist-dev

4-Get the libgpod code and compile it:

$ git clone git://gtkpod.git.sourceforge.net/gitroot/gtkpod/libgpod
$ cd libgpod
$ CFLAGS=”-g -O0″ sh autogen.sh –prefix=/usr
$ make
$ sudo make install

5-Create a folder to mount it, and mount it:

sudo mkdir /media/ipod

**connect your iPhone**

sudo ifuse /media/ipod

6-Create the needed directory and files:

cd /media/ipod/iTunes_Control
mkdir Device

Find your UUID with

lsusb -v | grep -i iSerial

grab your UUID wich is the 40 characters long text
and run the following command replaceing with yours:

ipod-read-sysinfo-extended /media/ipod

This has generated a needed file into the Device folder.

7-Thats it. Now you can open the gtkpod application and sync your iPhone.

Notes:
In order tu unmount your iphone first dissconect it via gtkpod and the you can use

sudo umount /media/ipod

And to mount it again just

sudo ifuse /media/ipod

There is a way to sync your files in the iphone, and also shering not only with ubuntu, but also with Windows or Mac.

It’s a free service called dropbox that offers 2Gb of space for your files.

1-Click here to go the dropbox website and create a free account.

2-Click on the Install link to Download dropbox and install it on your PC, there are versions avilable for Ubuntu, Fedora, and Sources (there are also Windows and Mac versions).

3-On Your iPhone go to the Apple Store and search for dropbox and install it.

4-Now You have a Dropbox folder in your PC, and a Dropbox app in your iphone. Any file that you copy to your Dropbox folder will appear on your iphone, and viceversa.

Have fun!

This is just another real case showing that Linux has become way much easier than Windows:

My daughter has a netbook with Windows XP, I have a Laptop with Ubuntu 9.10

We have a printer HP Deskjet 460 that we used today to print a drawing that my girl was making.

-In Windows XP, we plugged the printer, it detected some device asked for autodetection, I say yes, it did not found anything suitable…It asked to try via Windows Update, it found nothing, we choosed to specify model… It’s not listed…. we choosed similar models.. did’n worked…

My girl was irritated, so I said, OK let’s make a PDF email it to me and let’s try in Ubuntu:

-In Ubuntu I plugged the printer, it was deteced, installed, and we printed the drawing, just like that!

Ubuntu netbook remix includes maximus, which is an application that maximizes all the new windows and removes the decoration, this is is very good to make it easier to work with small screens, and even to save space in regular screens, the last is my case…

Well but sometimes maximus might annoy you because it maximizes all windows, even the ones that where designed to be small.

There is no maximus icon or preferences at first sight, but you can find it under the hood, via the gconf-editor:

So open the gconf-editor with the command:

gconf-editor

open /apps/maximus

You will see some options, that can help you to select applications that you don’t want to get maximized, you can keep decoration, and you can stop automatic maximization…play with that.

(Acrobat Reader is no longer in the medibuntu repository)

If you have upgraded to Ubuntu 9.10 (karmic kola) and want to install Acrobat Reader (acroread) you have to enable the canonical partners repository:

Go to the GNOME Menu : System > Administration > Software Sources

Select tab Other Sources

Mark: deb http://archive.canonical.com/ubuntu karmic partner

Reload your sources, either graphically or with:

sudo apt-get update

And then as usual simply install acroread via synaptic or with the command:

sudo apt-get install acroread

As a Linux fan, every time a new version of my current favorite distro -ubuntu- comes out (every six months) I download the ISO image burn it into a CD an perform a clean install. So I got a bunch of CDs, that I don’t really need after installation.

But not any more. This is what’s needed to do it from a USB flash drive and stop the CDs to pollute:

1. Download you ISO.
2. Install UNetbootin:
   

   sudo apt-get install unetbooting

3. Start it from Applications>System Tools>UNetbootin
4. Select your ISO file, and click on Accept.
5. One the USB is ready, boot from it and install Linux as yoiu would do it from the CD.

Notes:

1-UNetbootin Runs also from Windows

2-UNetbootin can download the ISO for you, but of course if it’s too know it migh not appear in the list…

Since Citrix XenServer is Linux, you just have to access by standard linux method: ssh
simpy initiate a ssh session with root account:

ssh root@yourserver.ip

and you are inside.

You will see a welcome text with the instructions:

Type “xsconsole” for access to the management console.

And once you type xsconsole you will get this:

I want to try a machine I got as a vmware image, so I went to install  the Free (as in beer) VMware player, this ois what it takes:

• There is no deb package so we must make sure we have the linux headers and build essentials:
  sudo apt-get install build-essential linux-headers-`uname -r`
• Go get the latest player version at : http://www.vmware.com/download/player/ make sure you download th .bundle version
• Execute it with root permissions with:
  gksudo bash VMware-Player-2.5.3-185404.i386.bundle

  Of course, change the file version in name as what you have (tab is your friend)

• A graphical installer will start, just click on install.
• And when completed just click close.
• That’s it it should be now in the GNOME Menu under Applications > System Tools > VMware Player

Usually,  you want to use your phone as a modem to provide internet access to your laptop, but there are somecases were you want the opposite, e.g. I’m in a foreing country, with no wifi internet, just wired access, how do I get my iPhone into the internet via WiFi and avoiding the muche expensive data roamig bucks? This is what I did:

I’m Using Ubuntu Linux and an iPhone.

-Connect the laptop to the wired internet.

-Click on the NetworkManager Applet

-Select “Create New Wireless Network…”

-Give a Name (e.g. MyOwnWiFi)

-If you want give a security option (e.g. WEP) and provide a password.

-Connect the iPhone to the new Wirless Network (no changes required, this shuld work in standard DHCP mode)

Ready to go.
