DESCRIPTION

16       vga  is  an Xorg driver for generic VGA video cards.  It can drive most
17       VGA-compatible video cards, but only makes use of  the  basic  standard
18       VGA  core that is common to these cards.  The driver supports depths 1,
19       4 and 8.  All relevant  visual  types  are  supported  at  each  depth.
20       Multi-head  configurations are supported in combination with some other
21       drivers, but only when the vga driver is driving the primary head.
22

SUPPORTED HARDWARE

24       The vga driver supports most VGA-compatible  video  cards.   There  are
25       some known exceptions, and those should be listed here.
26

CONFIGURATION DETAILS

28       Please  refer to xorg.conf(5x) for general configuration details.  This
29       section only covers configuration details specific to this driver.
30
31       The driver auto-detects the presence of VGA-compatible  hardware.   The
32       ChipSet  name  may  optionally be specified in the config file "Device"
33       section, and will override the auto-detection:
34
35           "generic"
36
37       The driver will only use 64k of video memory for depth 1  and  depth  8
38       operation,  and  256k of video memory for depth 4 (this is the standard
39       VGA limit).
40
41       When operating at depth 8, only a single built-in 320x200 video mode is
42       available.   At  other  depths there is more flexibility regarding mode
43       choice.
44
45       The following driver Options are supported:
46
47       Option "ShadowFB" "boolean"
48              Enable or disable use of the shadow framebuffer layer.  Default:
49              off.
50
51              This  option is recommended for performance reasons when running
52              at depths 1 and 4, especially when using modern PCI-based  hard‐
53              ware.   It  is  required when using those depths in a multi-head
54              configuration where one or more of the other screens is  operat‐
55              ing at a different depth.
