Problem with Keyring asking for Password after booting up.
I fined mine by editing the WIFI and checked the box that says Available to all users and it stopped asking me for the Keyring password.

Converting your existing .vmdk Virtual Disc Image To a .vdi File

NOTE: If you are converting a disk-image which contains a Windows installation, first follow the steps at http://www.virtualbox.org/wiki/Migrate_Windows

Now we need to convert your existing VMWare disc image into a format readable by VirtualBox. Don't worry, you won't lose any data but, just in case, you can always create a backup copy of your VirtualDisk before we start!

NOTE: If you have multiple vmdk-files like "vm.vmdk, vm-flat.vmdk, vm-0001.vmdk", you have to reorganize your .vmdk-files with: vmware-vdiskmanager -r vm.vmdk -t 0 hardrive-name.vmdk

* First of all, download qemu, you can do it using Synaptic or simply opening a Console and executing:

* sudo apt-get install qemu
o Now open a terminal and go into the folder where you’ve got your .vmdk virtual disc image and type this:

qemu-img convert harddrive-name.vmdk raw-file.bin

Naturally, you’ll have to change harddrive-name with the name of your .vmdk file and raw-file with the name of the new converted file you want to create. After a few minutes, the conversion will be completed. Now we’ve got a raw hard disk image and we want to transform it into a .vdi file

VBoxManage convertdd old-file.bin new-file.vdi

Also note that it will need to be applied for some upgrades:

Upgrade Alsa (1.0.23) on Ubuntu Lucid Lynx 10.04
May 2nd, 2010 by alpho2k | Print Upgrade Alsa (1.0.23) on Ubuntu Lucid Lynx 10.04
alsa Ubuntu Lucid Lynx 10.04 is coming by default with the version 1.0.21 of Alsa so I decided to upgrade to the last version wich is 1.0.23.

What is Alsa (Advanced Linux Sound Architecture) ?

According to Wikipedia, Alsa is a Linux kernel component intended to replace the original Open Sound System (OSS) for providing device drivers for sound cards. Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware, and graceful handling of multiple sound devices in a system, goals which it has largely met.

Installation :

To do this, we must begin by determining our version of alsa as follows :

cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21.

To avoid problems during the upgrade of Alsa-utils, we need to stop it with the following command :

sudo /sbin/alsa-utils stop
We must then install the necessary tools to compile along with the kernel headers :

sudo apt-get -y install build-essential ncurses-dev gettext xmlto libasound2-dev
sudo apt-get -y install linux-headers-`uname -r` libncursesw5-dev

Then, we go in our personal folder and download alsa-driver, alsa-lib and alsa-utils :

cd ~
rm -rf ~/alsa* ~/.pulse*
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.23.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.23.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.23.tar.bz2

After that, we create a new folder for the compilation and installation of the 3 files. Then, we move the 3 tar files that we just downloaded in this folder :

sudo rm -rf /usr/src/alsa
sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo cp ~/alsa* .

Unpack the 3 tar files :

sudo tar xjf alsa-driver*
sudo tar xjf alsa-lib*
sudo tar xjf alsa-utils*

We compile and install alsa-driver :

cd alsa-driver*
sudo ./configure
sudo make
sudo make install

We compile and install alsa-lib :

cd ../alsa-lib*
sudo ./configure
sudo make
sudo make install

We compile and install alsa-utils :

cd ../alsa-utils*
sudo ./configure
sudo make
sudo make install

Then, we remove the 3 tar files in our personal folder that are not anymore necessary :

rm -f ~/alsa-driver*
rm -f ~/alsa-lib*
rm -f ~/alsa-utils*

Then, just restart your computer and your alsa version should be 1.0.23!

You can verify that you have now indeed have this version of alsa :

cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on May 2 2010 for kernel 2.6.32-21-generic (SMP).

Just to be sure everything is well configured, execute this command :

sudo alsaconf

and reboot again!
