This driver for the X.Org X server (see xserver-xorg for a further description) uses the standard VESA interface provided on all video cards, but runs unaccelerated. This driver is not recommended for use unless you have a problem with the normal driver for your card, because it will perform very badly.

This package is built from the X.org xf86-video-vesa driver module.
