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

| tristate "MDA text console (dual-headed)" |
| help |
| Say Y here if you have an old MDA or monochrome Hercules graphics |
| adapter in your system acting as a second head ( = video card). You |
| will then be able to use two monitors with your Linux system. Do not |
| say Y here if your MDA card is the primary card in your system; the |
| normal VGA driver will handle it. |
| |
| To compile this driver as a module, choose M here: the |
| module will be called mdacon. |
| |
| If unsure, say N. |

| card of your Indy. Most people say Y here. |

| config FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION |
| bool "Enable legacy fbcon hardware acceleration code" |
| depends on FRAMEBUFFER_CONSOLE |
| default y if PARISC |
| default n |
| help |
| This option enables the fbcon (framebuffer text-based) hardware |
| acceleration for graphics drivers which were written for the fbdev |
| graphics interface. |
| |
| On modern machines, on mainstream machines (like x86-64) or when |
| using a modern Linux distribution those fbdev drivers usually aren't used. |
| So enabling this option wouldn't have any effect, which is why you want |
| to disable this option on such newer machines. |
| |
| If you compile this kernel for older machines which still require the |
| fbdev drivers, you may want to say Y. |
| |
| If unsure, select n. |
| |
| config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY |
| bool "Map the console to the primary display device" |
| depends on FRAMEBUFFER_CONSOLE |
| default n |
| help |
| If this option is selected, the framebuffer console will |
| automatically select the primary display device (if the architecture |
| supports this feature). Otherwise, the framebuffer console will |
| always select the first framebuffer driver that is loaded. The latter |
| is the default behavior. |
| |
| You can always override the automatic selection of the primary device |
| by using the fbcon=map: boot option. |
| |
| If unsure, select n. |
| |
| config FRAMEBUFFER_CONSOLE_ROTATION |
| bool "Framebuffer Console Rotation" |
| depends on FRAMEBUFFER_CONSOLE |
| help |
| Enable display rotation for the framebuffer console. This is done |
| in software and may be significantly slower than a normally oriented |
| display. Note that the rotation is done at the console level only |
| such that other users of the framebuffer will remain normally |
| oriented. |
| |
| config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER |
| bool "Framebuffer Console Deferred Takeover" |
| depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE |
| help |
| If enabled this defers the framebuffer console taking over the |
| console from the dummy console until the first text is displayed on |
| the console. This is useful in combination with the "quiet" kernel |
| commandline option to keep the framebuffer contents initially put up |
| by the firmware in place, rather then replacing the contents with a |
| black screen as soon as fbcon loads. |

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