xserver-xorg-video-vesa binary package in Ubuntu Focal amd64

 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.
 .
 More information about X.Org can be found at:
 <URL:https://www.X.org>
 .
 This package is built from the X.org xf86-video-vesa driver module.
