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

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

  71. depends on FRAMEBUFFER_CONSOLE
  72. default y if PARISC
  73. default n
  74. help
  75. This option enables the fbcon (framebuffer text-based) hardware
  76. acceleration for graphics drivers which were written for the fbdev
  77. graphics interface.
  78. On modern machines, on mainstream machines (like x86-64) or when
  79. using a modern Linux distribution those fbdev drivers usually aren't used.
  80. So enabling this option wouldn't have any effect, which is why you want
  81. to disable this option on such newer machines.
  82. If you compile this kernel for older machines which still require the
  83. fbdev drivers, you may want to say Y.
  84. If unsure, select n.
  85. config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
  86. bool "Map the console to the primary display device"
  87. depends on FRAMEBUFFER_CONSOLE
  88. default n
  89. help
  90. If this option is selected, the framebuffer console will
  91. automatically select the primary display device (if the architecture
  92. supports this feature). Otherwise, the framebuffer console will
  93. always select the first framebuffer driver that is loaded. The latter
  94. is the default behavior.
  95. You can always override the automatic selection of the primary device
  96. by using the fbcon=map: boot option.
  97. If unsure, select n.
  98. config FRAMEBUFFER_CONSOLE_ROTATION
  99. bool "Framebuffer Console Rotation"
  100. depends on FRAMEBUFFER_CONSOLE
  101. help
  102. Enable display rotation for the framebuffer console. This is done
  103. in software and may be significantly slower than a normally oriented
  104. display. Note that the rotation is done at the console level only
  105. such that other users of the framebuffer will remain normally
  106. oriented.

  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.

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