## 5. Configuring X for Your Hardware

The `/etc/X11/XF86Config` file tells the X server what kind of monitor, video card and mouse you have. You must create it to tell the server what specific hardware you have.

You'll need info on your hardware:

- Your mouse type, baud rate and its /dev entry.
- The video card's chipset (e.g. ET4000, S3, etc).
- Your monitor's sync frequencies.

The recommended way to generate an `XF86Config` file is to use the `xf86cfg` utility. The xf86config text utility is still there for the (few) cases where xf86cfg can't be used. Also, there is a sample file installed as `/usr/X11R6/lib/X11/XF86Config.eg`, which can be used as a starting point.

For details about the `XF86Config` file format, refer to the XF86Config(5) manual page.

Once you've set up a XF86Config file, you can fine tune the video modes with the `xvidtune` utility.

### 5.1. About mouse configuration

XFree86 4.8.0 has support for the mouse driver included in the new wscons console driver introduced by OpenBSD-2.9. Specify ```wsmouse`'' as the protocol and ```/dev/wsmouse0`'' as the device in `/etc/X11/XF86Config` if you're using OpenBSD-2.9 or later with a PS/2 or USB mouse.

See README.mouse for general instruction on mouse configuration in XFree86.
