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. config SGI_NEWPORT_CONSOLE tristate "SGI Newport Console support" depends on SGI_IP22 select FONT_SUPPORT help Say Y here if you want the console on the Newport aka XL graphics card of your Indy. Most people say Y here. config DUMMY_CONSOLE bool depends on VGA_CONSOLE!=y || SGI_NEWPORT_CONSOLE!=y default y config DUMMY_CONSOLE_COLUMNS int "Initial number of console screen columns" depends on DUMMY_CONSOLE && !ARM default 160 if PARISC default 80 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 int "Initial number of console screen rows" depends on DUMMY_CONSOLE && !ARM default 64 if PARISC default 25 help On PA-RISC, the default value is 64, which should fit a 1280x1024 monitor. Select 25 if you use a 640x480 resolution by default. config FRAMEBUFFER_CONSOLE bool "Framebuffer Console support" depends on FB && !UML select VT_HW_CONSOLE_BINDING select CRC32 select FONT_SUPPORT help Low-level framebuffer-based console driver. 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" depends on PARISC 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. endmenu |
