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 19″ widescreen LCD for 1440×900 resolution under Linux.

I’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 19” 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.

I’m using 1400×900 screen resolutions and I’m quite happy with this display unit. Now I can view MRTG graph, monitor routers and server on a large screen. At work place I’ve 24” widescreen LCD monitor.

However my desktop system is quite old. It has Intel Celeron 1.7Ghz with 512+256 MB RAM. I’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!

Howto: Performance Benchmarks a Webserver

You can benchmark Apache, IIS and other web server with apache benchmarking tool called ab. Recently I was asked to performance benchmarks for different web servers.

It is true that benchmarking a web server is not an easy task. From how to benchmark a web server:

First, benchmarking a web server is not an easy thing. To benchmark a web server the time it will take to give a page is not important: you don’t care if a user can have his page in 0.1 ms or in 0.05 ms as nobody can have such delays on the Internet.

What is important is the average time it will take when you have a maximum number of users on your site simultaneously. Another important thing is how much more time it will take when there are 2 times more users: a server that take 2 times more for 2 times more users is better than another that take 4 times more for the same amount of users.”

Here are few tips to carry out procedure along with an example:
