vga - Generic VGA video driver
vga is an Xorg driver for generic VGA video cards. It can drive most
VGA-compatible video cards, but only makes use of the basic standard
VGA core that is common to these cards. The driver supports depths 1,
4 and 8. All relevant visual types are supported at each depth.
Multi-head configurations are supported in combination with some other
drivers, but only when the vga driver is driving the primary head.
The vga driver supports most VGA-compatible video cards. There are
some known exceptions, and those should be listed here.
Please refer to xorg.conf(5) for general configuration details. This
section only covers configuration details specific to this driver.
The driver auto-detects the presence of VGA-compatible hardware. The
ChipSet name may optionally be specified in the config file "Device"
section, and will override the auto-detection:
The driver will only use 64k of video memory for depth 1 and depth 8
operation, and 256k of video memory for depth 4 (this is the standard
When operating at depth 8, only a single built-in 320x200 video mode is
available. At other depths there is more flexibility regarding mode
The following driver Options are supported:
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer. Default:
This option is recommended for performance reasons when running
at depths 1 and 4, especially when using modern PCI-based hard‐
ware. It is required when using those depths in a multi-head
configuration where one or more of the other screens is operat‐
ing at a different depth.
