Welcome to the LinuxFocus March 2001 issue

I hope you enjoy reading LinuxFocus. With every issue I am getting feedback from many readers who like the magazine and see the unique benefits that a free multilingual magazine for Linux has. An information source not only available in English. It helps to spread Linux and the idea behind it around the globe.
LinuxFocus has many readers. I genuinely like readers like you, interested to explore new things about Linux or just passing by to read an article. Yes, LinuxFocus is there for you as a reference and you can consult it at no extra cost.

Many readers feel that they would like to contribute back. Well, it's easy. Promote LinuxFocus and its idea. No, you don't need to paint a big poster. Tell a friend about it or engage in LinuxFocus. Translate an article to your mother tongue. To do that just get in touch with the editor of the respective language section. There are even a number of articles waiting to be translated to English.

The LinuxFocus Tip

1. Edit your ~/.xinitrc file. If you do not have one in your home directory then you might be using the system wide file
   /usr/X11R6/lib/X11/xinit/xinitrc
   Copy it to your home directory as .xinitrc and edit it then.
2. Add the line

   xset -b
   

   at the beginning of the file
3. After the next start of X-windows your computer will not beep anymore.
