|The best tweak-er, ever!...|
It has a configuration editor of its own called Gconf which is one of the best ways to customize or change a lot of settings the desktop does not allow by default. But, until you're are a bit familiar with it or even after getting familiar, yet, there are few tweaks that are hard to perform because of the lack of a professional looking GUI.
Anyway, if you want to change Ubuntu completely by using a single, easy to use free utility, then I highly recommend the Ubuntu Tweak!. It comes with a simple yet elegant looking GUI and lets you do things like...
*. View full details of your currently installed hardware.
*. Change few settings of Nautilus (including extensions, etc) that are hidden by default.
*. Install few popular applications with ease.
*. Clean package manager database.
*. Show/hide computer, home or trash icons on desktop.
*. Change metacity window manager behavior (title bar size, transparency, mouse hoover effects, etc).
*. Compiz window manager customizations.
*. Customize Gnomes start-up applications.
*. Third party app installing (Skype, Opera, etc).
*. Log-in sound settings.
*. Change default folder locations/paths (for Home, music, videos, etc).
*. Panel and notification settings... are few to mention.
So if you have installed Ubuntu 10.10 and want to install Ubuntu tweak using PPA, then open your terminal and issue the below command,
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak
