Free ubuntu tweaker software for linux

UbuntuTrinux seeks to integrate elements (and code, where appropriate) of Trinux with the Debian/Ubuntu mkinitramfs infrastructure to allow easy development and packaging Ubuntu binary (and ultimately package and repository) compatible ramdisk distributions using recent 2.6.x kernels. As before, the most common use is network security monitoring and analysis.

Trinux: A Linux Security Toolkit was a ramdisk-based Linux distribution that was under active development from 1998-2003.

Ubuntu Center is a web based interface for accessing all kinds of information thats being stored on your computer running Ubuntu Breezy, XUbuntu, Kubuntu or even nUbuntu box.
Ubuntu Center accomplishes all of this by integrating PHP software licensed under the GPL license in one giant package suitable for use on a Ubuntu computer. This release adds tons of new features and bug fixes and is suitable for everyday use.
Enhancements:
- A Web-based installer was implemented and an admin area was added.

Kubuntu is an Ubuntu-derived distribution. The Kubuntu CDs are made up of Ubuntus base plus KDE. You can get exactly the same effect by installing Ubuntu and adding the KDE packages from the Ubuntu archives.

Kubuntu is the result of several months effort to get KDE 3.4 into Ubuntus main repository and create the first major derived Ubuntu distribution. Kubuntu is not a fork of Ubuntu but an official project of it, sharing the same package archive and infrastructure. It is possible to convert an Ubuntu system to Kubuntu or vice versa.

Xubuntu community projects aim is to provide a nice Ubuntu desktop experience (even on older hardware) by using Xfce4 as the desktop environment and GTK+ 2 applications wherever possible.

Xfce4 has been supported in Ubuntus universe by the MOTUXfce team since Hoary and Breezy. For Dapper we want to go one step further and make Xubuntu a sibling of Ubuntu, Kubuntu, and Edubuntu by having install and live CD images generated for it.

As Ubuntu has a delay of six weeks with a new release date of the first of June, Xubuntu should be released at the same time and should use the latest stable Xfce 4.X code (hopefully 4.4 will be released by then).

Edubuntu is a version of the Ubuntu operating system suitable for classroom use. As an educator youll be able to set up a computer lab, or establish an online learning environment, in an hour or less -- then administer that environment without having to become a fully-fledged Linux geek.

Edubuntu is currently under development by the same development team that produces the wildly popular Ubuntu system. Edubuntu a customized version of Ubuntu.

Principal design goals of Edubuntu are centralized management of configuration, users, and processes, together with facilities for working collaboratively in a classroom setting. Equally important is the gathering together of the best available free software and digital materials for education.

Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM. It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting. We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.
WARNING: The author asserts that this procedure works for him, but cannot guarantee that this procedure works for anyone else. Although this procedure is meant to be 100% safe, it is feasible that there may be mistakes, or a chance of misunderstanding the instructions in a manner that causes loss of data. Please make a backup and do not attempt on mission critical systems. Read through this article thoroughly, and do not attempt if you do not comprehend or feel comfortable about any of the instructions!
CAUTION: I hope this is intuitively obvious, but Ill humor you and state it bluntly: Changes you make under the live session are NOT saved and WILL BE LOST when you reboot or shut down. Dont save anything important to the "home directory" and expect it to still be around! If you want to save data permanently, mount a permanent medium (such as your hard drive), plug in a thumbdrive, or use some network functionality built into Ubuntu to save your data to a non-volatile destination.
There are many cases where one would like to boot Ubuntu to RAM:
- Performance: The desktop performance is dramatically improved. A 400MB squashed filesystem in RAM, that holds 1200MB of data, is read back on a 1.6GHz Core Duo in about 3 seconds, including decompression time.
- Power, Noise, Durability: Although modern hard disks dont use much power compared to other system components, this may still be important for some. In laptops, hard disks are often the noisiest components, so this setup can reduce system noise. With the hard disk spun down, a laptop can potentially withstand greater shocks without damage.
- Abrupt poweroff: Since the hard disk is only momentarily used in read-only mode during boot, then never touched again, there are few or no negative consequences of an abrupt poweroff. If a system is used where power is inconsistent, or the system is regularly used in a context where fast shutoffs are required, this is very handy.
- Privacy: Anything you do in this session are lost when you reboot or power off. This is great for kiosks or other systems where permanent modification are not desired. (Note that by default the livecd user has full sudo access, so potentially a malicious user can still make permanent changes by mounting the hard drive and following this HOWTO)
