Linux operating systems comes with various set of tools allowing you to manipulate the Wireless Extensions and monitor wireless networks. This is a list of tools used for wireless network monitoring tools that can be used from your laptop or desktop system to find out network speed, bit rate, signal quality/strength, and much more.
Every IT shop has a mix of Windows and Linux system. Sometime you need to authenticate your Linux desktop system against Microsoft Active Directory service. You can save time, effort and IT infrastructure by sharing authentication server. This article explains how to setup the Linux desktop computers with Active Directory using Samba and winbind.

This is a good news for all European Linux users. You can now order Dell Laptop preloaded with Ubuntu Linux 7.10.
From the Dell blog:
Starting today, customers in Germany, United Kingdom, France and now Spain can purchase Ubuntu Linux 7.10 with built-in DVD playback on the XPS 1330n (in addition to the previously-released Inspiron 530n desktop system. For U.S. customers, you’ll have to hold on a week or so.
Ubuntu 7.10 runs great on the XPS M1330. It has more power, more style. Take a look at the Dell Ubuntu website for more details.
I was just wondering why this feature wasn’t included in X from the day one. Ubuntu Xorg maintainer Bryce Harrington recently demonstrated the BulletProof-X feature that is planned for inclusion in Ubuntu 7.10:
This specification describes a new failsafe mode that will be used if X fails to start up. It will be in a reduced (VESA 800×600/256 or VGA 640×480/16) graphics environment running a single application (displayconfig-gtk) for configuring the graphics devices.
The goal of this specification is to eliminate the need for users to need to run apt-get reconfigure on the commandline. That approach is confusing and too technical for many users, so moving away from that will solve a key pain point for users.
This is useful if the user has changed monitors or graphics cards or X failed to detect your hardware. Linux based desktop system getting better and better everyday 🙂
As I said earlier you need to tweak few things to run this monitor with Intel 810 or 845 based chip-set under Ubuntu Linux.
In order to use higher resolution install updated Intel i8xx, i9xx display driver. It is provided by a package called xserver-xorg-video-intel. This package provides the driver for the Intel i8xx and i9xx family of chipsets, including i810, i815, i830, i845, i855, i865, i915, and i945 series chips.
Replace driver by running the apt-get command. Open your terminal and type command:
$ sudo apt-get install xserver-xorg-video-intel
Now run ddcprobe command to get monitor VertRefresh values and HorizSync rate:
$ sudo ddcprobe | grep monitorrange
monitorrange: 24-82, 50-75
24-82 is your HorizSync rates and the second pair is your VertRefresh (50-75) values.
Next reconfigure xserver (X.org) video and monitor using auto detect feature:
$ sudo dpkg-reconfigure xserver-xorg
Set monitor resolution 1440 x 900 and others as per your requirement. Save the changes and reboot the system.
After login you can adjust screen resolution by visiting System > Preferences > Screen Resolution > Select desired screen resolution such as 1440 x 900 and save the changes.
Update: See howto configure Viewsonic VG1930WM 19â€³ widescreen LCD for 1440Ã—900 resolution under Linux.
Iâ€™ve been thinking to post about this for a while. My old 15″ CRT monitor died three weeks ago. I decided to replace the faulty monitor with the 19â€ ViewSonic and I’m glad I did.
The monitor works with Ubuntu Linux with little tweaks in X.ORG configuration file.. It is a remarkable monitor with a decent price tag.
Iâ€™m using 1400×900 screen resolutions and Iâ€™m quite happy with this display unit. Now I can view MRTG graph, monitor routers and server on a large screen. At work place Iâ€™ve 24â€ widescreen LCD monitor.
However my desktop system is quite old. It has Intel Celeron 1.7Ghz with 512+256 MB RAM. Iâ€™m thinking to upgrade this box with AMD 64 X2 5600+, MSI Diamond motherboard with RAID 5, SATA II, 2 Gig DDR2, and 512 MB graphics card. If you know better hardware configuration please add your thoughts in comments!
