| 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. |

| config VGACON_SOFT_SCROLLBACK |
| bool "Enable Scrollback Buffer in System RAM" |
| depends on VGA_CONSOLE |
| default n |
| help |
| The scrollback buffer of the standard VGA console is located in |
| the VGA RAM. The size of this RAM is fixed and is quite small. |
| If you require a larger scrollback buffer, this can be placed in |
| System RAM which is dynamically allocated during initialization. |
| Placing the scrollback buffer in System RAM will slightly slow |
| down the console. |
| |
| If you want this feature, say 'Y' here and enter the amount of |
| RAM to allocate for this buffer. If unsure, say 'N'. |
| |
| config VGACON_SOFT_SCROLLBACK_SIZE |
| int "Scrollback Buffer Size (in KB)" |
| depends on VGACON_SOFT_SCROLLBACK |
| range 1 1024 |
| default "64" |
| help |
| Enter the amount of System RAM to allocate for scrollback |
| buffers of VGA consoles. Each 64KB will give you approximately |
| 16 80x25 screenfuls of scrollback buffer. |
| |
| config VGACON_SOFT_SCROLLBACK_PERSISTENT_ENABLE_BY_DEFAULT |
| bool "Persistent Scrollback History for each console by default" |
| depends on VGACON_SOFT_SCROLLBACK |
| default n |
| help |
| Say Y here if the scrollback history should persist by default when |
| switching between consoles. Otherwise, the scrollback history will be |
| flushed each time the console is switched. This feature can also be |
| enabled using the boot command line parameter |
| 'vgacon.scrollback_persistent=1'. |
| |
| This feature might break your tool of choice to flush the scrollback |
| buffer, e.g. clear(1) will work fine but Debian's clear_console(1) |
| will be broken, which might cause security issues. |
| You can use the escape sequence \e[3J instead if this feature is |
| activated. |
| |
| Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each |
| created tty device. |
| So if you use a RAM-constrained system, say N here. |
| |
| config MDA_CONSOLE |
| depends on !M68K && !PARISC && ISA |
| 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. |

| help |
| On PA-RISC, the default value is 160, which should fit a 1280x1024 |
| monitor. |
| Select 80 if you use a 640x480 resolution by default. |
| |
| config DUMMY_CONSOLE_ROWS |

| 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 STI_CONSOLE |
| bool "STI text console" |

| select FONT_SUPPORT |
| default y |
| 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. |
