I followed the procedure outlined by UbuntuGeek, but some of the things are little different – at least when I installed it today.
First, you’ll need to add the repository which contains the deb for Chrome.
sudo gedit /etc/apt/sources.list
Assuming you are running Karmic Koala (Ubuntu 9.10), you’ll need to add the following two lines towards the end of that file.
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main
Next, you’ll have to retrieve the PGP keys for this repository.
sudo add-apt-repository ppa:chromium-daily/ppa
Update the sources,
sudo apt-get update
And then instal Chrome
sudo apt-get install chromium-browser
After the installation is successful, you can launch the browser, and import settings from Mozilla Firefox. However, Firefox needs to be closed when the importing of options and favourites is taking place. When Chrome restarts, it will have options configured like you had them in Firefox. The are no add-ons that I could find for Chrome, though – Adblock Plus and Video Download Helper are the two plugins that would make me stick with Firefox for a while.

Sometimes when you change some of the IP settings, or are using a different wireless card on a machine that has been registered with a server, and for many other reasons, you might have encountered a warning which would’ve looked like this:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
f2:92:1d:da:81:2a:d7:16:0a:48:f0:43:20:1c:f4:b5
………………..
The simplest way to deal with this is to remove the ~/.ssh folder, however this clears out all the exchanged keys with all the ssh machines you have ever communicated with. Removing the ~/.ssh folder would mean that each time you reconnect to a SSH server that you have previously connected to, you will have to confirm that the connection is secure and all that.
There is however another simple way to change just the entry for a specific server in question. At the terminal type in -
ssh-keygen -R name_of_the_server.com
name_of_the_server.com in the above example would need to be replaced by the actual server name that you are trying to connect.

The GDM in Ubuntu changed a bit since Karmic. Now you no longer need to type in both username and password. Instead there is a list of users that shows up, similar to what we have in Windows and Mac. That way you don’t accidentally type in the password when you are supposed to be typing your user name. While this is a really nice way to login, Ubuntu added a drum sound which plays each time you arrive at the login screen – this can be when a user logs out or starts the computer. There is no simple way to disable that sound using GUI. There is however a simple command line which disables this login screen sound as lets you login silently.
If you are a sudoer, open up the terminal and type in:
sudo -u gdm gconftool-2 –set /desktop/gnome/sound/event_sounds –type bool false
The next time you logout, or restart the computer, the sound won’t be played again.

Update: The above methods doesn’t work for everyone. There have been a couple of other methods that have been known to work.
To actually disable the “login ready” sound you need to edit your /etc/gdm/custom.conf file.
sudo gedit /etc/gdm/custom.conf
Under the [greeter] section add the line:
SoundOnLogin=false
Another method that has worked for some is the removal of ubuntu-sounds package. This will remove all the event sounds as well, but your media should work just fine.
sudo apt-get remove ubuntu-sounds
These are some of the methods that have worked for several people. YMMV – unfortunately.
