Running Nvidia display drivers with X.Org 7.3

This morning, hardworking Debian developers pushed the remaining pieces of the brand new X.Org 7.3 to Debian sid (unstable) distribution. And it must be said, a well done job!

The Little Book of Semaphores, 2nd Edition

By Allen B. Downey
Second Edition Revision date July 2007

The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.

In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.

Nvidia Linux driver 1.0-9639, 1.0-7185 and Linux kernel 2.6.23

Referencing the post Nvidia Linux driver 100.14.11 and Linux kernel 2.6.23. Here I have attached the patches for the older versions of Nvidia drivers. The procedure to follow is the same as described in the above document.

Building Debian FreeRadius package with EAP/TLS/TTLS/PEAP support

Debian's FreeRadius package is built without support for EAP/TLS/TTLS/PEAP because of the licensing problems of the OpenSSL library. But, if you want to implement 802.1x network authentication with strong security, you'll need it. This is a short tutorial that explains how to build Debian (sid aka unstable) package linked to libssl and with EAP/TLS/TTLS/PEAP support compiled in.

A First Look at Oracle 11g database on Debian GNU/Linux

[img_assist|nid=379|title=|desc=|link=none|align=left|width=164|height=29]Three and half years have passed since my first attempts to install Oracle 10g on an unsupported Debian GNU/Linux distribution. Seeing that Oracle 11g is out, and exclusively for Linux at this time, I decided to download it among the first and see and share with you what it's installation looks like.

GNOME Desktop project 10 years old!

[img_assist|nid=1030|title=|desc=|link=none|align=left|width=100|height=114]Exactly 10 years ago, on 15th August 1997, Miguel de Icaza started his first announcement about GNOME Desktop project with this words:

We want to develop a free and complete set of user friendly applications and desktop tools, similar to CDE and KDE but based entirely on free software:

Renegotiate ethernet card link speed / duplex

Due to software or hardware (network switch or ethernet card) error it may be possible that you need to restart auto-negotiation on the ethernet device. Here's how to do it:

mii-tool -r eth0


ethtool -r eth0

Then check the kernel log to see what happens:

% dmesg
eth0: link down
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

Thanks for this tip goes to Vivek.

Nvidia Linux driver 100.14.11 and Linux kernel 2.6.23

Well, they're not working together. Unless you're not willing to tweak it a little bit. So, out of the box, you won't be able to test brand new Linux CFS scheduler, merged in the 2.6.23-rc1 release, if you drive your Nvidia card with the proprietary driver. I guess that's what we get for running binary drivers.

Your ATI Radeon very slow on Xorg X server 1.3?

This one has bothered me for a long time. The solution is, of course, simple. But, I still don't understand why was it necessary to force users to search so hard for this piece of information, where all the older X server releases worked OK out of the box?

If you find that after upgrading to X.Org 7.3 your display becomes very slow, and you own ATI Radeon, all you need to do is to put this line in the Device section of your xorg.conf:

Option "MigrationHeuristic" "greedy"
