Tip 44: Mouse problems

The mouse is a very important part of a computer. In X, you can't do much without it. Even in console some applications will allow you to use it. You must first configure it.

Like every other device, the mouse has a device file in the /dev directory. Depending on your mouse type, it will be either /dev/psaux for a PS/2 mouse, or /dev/cua0 for a serial mouse on COM1.

To make it easy to use in the future, you should link the right device file to /dev/mouse: ln -s /dev/cua0 /dev/mouse

Then, when you configure X Window or any other program that requires a mouse, you can specify /dev/mouse.
