Free ubuntu tweak review 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 Multimedia Center is a complete Linux-based operating system, freely available with community and professional support. Ubuntu Multimedia Center is developed by Zach Thibeau but I want you to participate too!

WARNING! Users in countries that dont allow use of mp3 playback or DVD playback are advised to remain using the regular release of Ubuntu.

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.

i815 linux tweak project is i815-family chipset tweaker and optimizer for improve performance. Remember that some settings can crash your system.

USE AT YOUR OWN RISK

Installation:

From root user tpye "./install.sh".
If success, module will compile and plased into modules directory.

Usage:

modprobe i815tweak

Without any parameters nothing changes. In /proc/i815info you can see actual chipset settings.

Or see "dmesg" for error info..

For list all module parameters check "modinfo i815tweak".

cas=[2,3]
CAS# Latency (CL)

ras2cas=[2,3]
SDRAM RAS# to CAS# Delay (SRCD)

ras=[2,3]
SDRAM RAS# Precharge (SRP)

refX=[0-7]
SDRAM Mode Select (SMS). These bits select the operational mode of the MCH DRAM interface. The special modes are intended for initialization at power up.

0 = DRAM in Self-Refresh Mode, Refresh Disabled
1 = Normal Operation, 100 MHz System memory – Refresh interval 15.6 uSec
133 MHz System memory – Refresh interval 11.7 uSec
2 = Normal Operation, 100 MHz System memory – Refresh interval 7.8
133 MHz System memory – Refresh interval 5.85 uSec
3 = Normal Operation, 100 MHz System memory – Refresh interval 1.28 uSec
133 MHz System memory – Refresh interval 0.96 uSec
4 = NOP Command Enable. In this mode all processor cycles to SDRAM result in a NOP Command on the SDRAM interface.
5 = All Banks Precharge Enable. In this mode all processor cycles to SDRAM result in an All Banks Precharge Command on the SDRAM interface.
6 = Mode Register Set Enable. In this mode all processor cycles to SDRAM result in a mode register set command on the SDRAM interface.
7 = CBR Enable. In this mode all processor cycles to SDRAM result in a CBR cycle on the SDRAM interface.

dct57=[0, 1]
DRAM Cycle Time (DCT). This bit controls the number of SCLKs for an access cycle.
0 = Tras = 7 SCLKs and Trc = 9 SCLKs.
1 = Tras = 5 SCLKs and Trc = 7 SCLKs (Default)

bnr=[0,1]
Block New Request Lookahead

agp=[0,1]
AGP4X Override

sba=[0,1]
Sideband Address Enable (SBA)
1 = Enable. The sideband addressing mechanism is enabled.
0 = Disable

fw=[0,1]
Fast Writes Enable (FW). This bit must always be programmed to 0. The chipset will behave
unpredictably if this bit is programmed with 1.

cpc=[0,1]
Command per cycle

sm=[0,1]
SM Always Bypass

hacqs=[0,1]
Host Aperture Cycle Queue Slot
0 = Default value. No dedicated queue
1 = A dedicated queue slot is reserved

clt=[0,1]
CPU Latency Timer
0 = Deferrable processor cycle will be Deferred immediately after receiving another ADS#
1 = Deferrable processor cycle will only be Deferred after in has been held in a “Snoop Stall” for 31
clocks and another ADS# has arrived (default).

dpcp=[0,1]
DRAM Page Closing Policy (DPCP)
0 = Precharge All during the service of any “Page Miss” access.
1 = Precharge All during the service of any “Page Miss” access.

magwe=[0,1]
Memory Arbiter Grant Window Enable (MAGWE).
0 = Disabled. Enforce fixed priority.
1 = 24 clocks limiting host, 24 clocks guaranteed to low priority graphics stream.

EXAMPLE:

modprobe i815tweak cas=2 ras2cas=2 ras=2 bnr=1 dct57=1

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.
