Nvidia Releases A Performance And Debug Tool For Linux

NVIDIA has, more often than not, been extremely helpful when it comes to making sure it is supportive of the desktop market. Today’s post just goes to reaffirm this, I think.

NVPerfKit is a comprehensive suite of performance tools to help debug and profile OpenGL and Direct3D applications. It gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved.

NVPerfKit 2.1 now includes support for 64-bit Windows platforms, as well as 32-bit and 64-bit Linux platforms. Other improvements include an updated installer, Release 90 driver support, enhancements to NVPerfHUD, and more.

The performance counters are available directly in your OpenGL and DirectX applications and in tools such as Intel VTune and Graphic Remedy’s gDEBugger via the Windows Management Instrumentation (WMI) Performance Data Helper (PDH) interface. A plug-in supporting Microsoft PIX for Windows is also provided, giving you low-latency access to NVPerfKit performance counters directly from the driver… [Source: LinuxLookup]


HOWTO Access A Superfast Linux Desktop From Anywhere Using FreeNX

I think this is great! Discover just how to access your desktop from just about anywhere!

FreeNX allows superfast and secure access to your Linux box from anywhere in the world. This HOWTO is a step-by-step guide for configuring the nxserver, generating custom encrypted keys, and using a combination of Live-CD and USB thumbdrive to create a portable nxclient for remote access.

0 – Start

FreeNX is the GPL-ed free software version of the NXserver technology developed by NoMachine. NX squeezes the fat and chatter out of Xsessions, making possible the use of Linux GUI desktops and applications in remote locations with extreme response over limited bandwidth. Using KDE over FreeNX with a DSL connection is a “like I was right there” experience… little to no lag at all! Even a modem connection gives up a usable computing experience.
This HOWTO uses Kanotix Linux, a Live-CD distribution that can be run entirely from CD or installed to a hard drive….. Source: biohackery.com

Animate the Desktop with Xgl and Compiz

t’s cooler than anything Microsoft has by far, but is it really part of a better computing experience?

To get working well, it is essential to harness the 3-D rendering capabilities of your graphics card and setup the plug-ins with the composite window manager, This excerpt is from Chapter 3: Using SUSE Linux on Your Desktop, from the book By Chris Brown PhD, published by O’Reilly Media.

Section 12: Animate the Desktop with Xgl and Compiz

Given the rapid pace of software development in the Linux world, it is inevitable that some topics that are bleeding-edge as this book goes into production will be mainstream technology by the time you get to read it. One such is the Xgl X server and the compositing window manager compiz. Together with a modern graphics card, these components (which are shipped with SUSE Linux 10.1) offer some stunning visual desktop effects comparable (dare I say this?) to the best that the Mac has to offer. These effects include transparent windows, fade-in/fade-out of windows and menus, animated window minimization, and the ability to put four desktops onto four faces of a cube and spin the cube (in 3-D) to switch desktops. The overall result is to give the desktop a more fluid, organic feel…. Source: Linux Journal

A glimpse into 3D desktops…

3D vs 3D desktop environments. Below is a great explanation of the offering of both flavors; Red Hat and Novell.

I’ve been talking about them, complaining about what you CAN’T do, about the troubles with 3D cards… Personally I’m getting a bit lost with all this. So, I’ve decided to compile all the information I could find out about those pesky 3D desktops.

Comments required.
A “what is” guide to 3D desktops
Essentially developed by Novell for SuSE and the first “elegant” 3D desktop, it came out with Compiz, a window manager that can replace Gnome’s (and now KDE’s and others) window manager. Allowing desktop rotations, window transparencies and deformations, it is nice-looking, fluid and can run on hardware more than five years old.
In short, if your existing X configuration supports somewhat advanced 3D acceleration and DRI, you can run XGL: it will start your normal X, ask it to draw a single, full-screen OpenGL window in which a simple new X server runs… Source: Free Software Mag

Windows Linux DualBoot Tutorial

For all of you who are still trying to wrap your minds around dual booting with Windows and Linux, here is a tutorial to help light your way. While it may not actually do the dirty work for ya, it might save you a few hours of frustration.

This tutorial was written to help set up a dual boot on a SATA drive but it will also work for PATA so continue forward and I will let you know if you need to skip something. In order to have a fully functional dual boot system it is preferred that Windows be loaded first. After that you can load Linux and easily dump the boot configuration on Windows NTLDR file (comparable to Linux boot file).

At least one of the following scenarios exist and that is why you are here reading this tutorial; Source: Howtoforge

Why doesn’t Linux need defragmenting?

Linux has always been better than Windows is many ways.. one of them being that Linux doesn’t need to be defragged.

Read this excellent article to know why.
