Supported video hardware

To avoid problems, it is important to verify XFree86 compatibility with your hardware prior to installation. At the very least, you should be aware of these items:

Your X.Org version

As with any software, improvements in X.Org are made over time, particularly in support for hardware devices.

X.Org video drivers are written for graphics chipsets, not the video cards on which they’re installed.

Monitor type

X.Org can be configured to handle just about any monitor, particularly the newer and very flexible multisync monitors sold today, which can handle preset configurations provided in the X.Org Foundation configuration utilities.
