  14        help
  15          Saying Y here will allow you to use Linux in text mode through a
  16          display that complies with the generic VGA standard. Virtually
  17          everyone wants that.
  18
  19          The program SVGATextMode can be used to utilize SVGA video cards to
  20          their full potential in text mode. Download it from
  21          <ftp://ibiblio.org/pub/Linux/utils/console/>.
  22
  23          Say Y.

  28        help
  29          Say Y here if you have an old MDA or monochrome Hercules graphics
  30          adapter in your system acting as a second head ( = video card). You
  31          will then be able to use two monitors with your Linux system. Do not
  32          say Y here if your MDA card is the primary card in your system; the
  33          normal VGA driver will handle it.
  34
  35          To compile this driver as a module, choose M here: the
  36          module will be called mdacon.
  37
  38          If unsure, say N.

  45          Say Y here if you want the console on the Newport aka XL graphics
  46          card of your Indy.  Most people say Y here.

  58          On PA-RISC, the default value is 160, which should fit a 1280x1024
  59          monitor.
  60          Select 80 if you use a 640x480 resolution by default.

  84       default n
  85        help
  86         If this option is selected, the framebuffer console will
  87         automatically select the primary display device (if the architecture
  88         supports this feature).  Otherwise, the framebuffer console will
  89         always select the first framebuffer driver that is loaded. The latter
  90         is the default behavior.
  91
  92         You can always override the automatic selection of the primary device
  93         by using the fbcon=map: boot option.
  94
  95         If unsure, select n.

 100       help
 101         Enable display rotation for the framebuffer console.  This is done
 102         in software and may be significantly slower than a normally oriented
 103         display.  Note that the rotation is done at the console level only
 104         such that other users of the framebuffer will remain normally
 105         oriented.
 106
 107config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER

 110        help
 111          If enabled this defers the framebuffer console taking over the
 112          console from the dummy console until the first text is displayed on
 113          the console. This is useful in combination with the "quiet" kernel
 114          commandline option to keep the framebuffer contents initially put up
 115          by the firmware in place, rather then replacing the contents with a
 116          black screen as soon as fbcon loads.

 125          The STI console is the builtin display/keyboard on HP-PARISC
 126          machines.  Say Y here to build support for it into your kernel.
 127          The alternative is to use your primary serial port as a console.
