Larswm Debian desktop.
The Larswm window manager deserves to be given a try if you want a fast and flexible window manager to use on a netbook or low specced desktop machine. This window manager is very fast and usable for any user that wants to use a desktop that is free from bloat. Using a fully featured Linux desktop like KDE or Gnome on a netbook is defeating the purpose; even though my ASUS eePC can run Gnome Shell ok; the Larswm window manager is faster and more usable and you can have a thin bar at the bottom of the screen that contains the name of the application you are running; the workspace navigator; the system information and the clock. That is a very usable and informative bar and provides all of the information you need to use the desktop properly. This below is my .larswmrc I am using on my netbook.

And this is my .xinitrc file that will get this desktop working.
xterm & larsclock & larsmenu & exec larswm
There is a nice ~/.larswmrc file here if you want to try another example: .
How to create an alias to shorten a command. This example is shortening the clear command to cls.
alias cls='clear'

I am a computer enthusiast that has always been interested in maintaining and upgrading computer hardware. I was born on a farm and lived there for 13 years before moving into town. I was always interested in technology and my father always gave me good encouragement for developing my knowledge and interest in tinkering with computers. He was using a computer on the farm but that was in the very late 80`s and late 90`s. Seeing what a computer could do always fascinated me and then I knew that is what I wanted to do. The first time I used Linux was Red Hat 6.2 installed off a single CDROM and I was amazed that you did not need to install any more drivers on my old Intel Celeron machine to be able to enjoy a nice 24BPP desktop and use the GIMP to edit photos and enjoy playing the old Linux games like Xbill. Then a while later I tried Mandrake Linux 9.2 and I was hooked. It came with so much software and was very easy to use as well. Then Mandrake Linux 10 and on through FreeBSD, Debian 3.0, Debian 3.1 Suse Linux 9.2, Suse 10 and onto the Ubuntu distributions although I am using Fedora Core 15 and the Gnome 3 desktop at the moment.
