Virtually 18 everyone wants that. 19 20 The program SVGATextMode can be used to utilize SVGA video cards to 21 their full potential in text mode. Download it from 22 <ftp://ibiblio.org/pub/Linux/utils/console/>. 23 24 Say Y. 25 26config MDA_CONSOLE 27 depends on !M68K && !PARISC && ISA 28 tristate "MDA text console (dual-headed)" 29 help 30 Say Y here if you have an old MDA or monochrome Hercules graphics 31 adapter in your system acting as a second head ( = video card). You 32 will then be able to use two monitors with your Linux system. Do not 33 say Y here if your MDA card is the primary card in your system; the 34 normal VGA driver will handle it. 35 36 To compile this driver as a module, choose M here: the 37 module will be called mdacon. 38 39 If unsure, say N. 40 41config SGI_NEWPORT_CONSOLE 42 tristate "SGI Newport Console support" 43 depends on SGI_IP22 && HAS_IOMEM 44 select FONT_SUPPORT 45 help 46 Say Y here if you want the console on the Newport aka XL graphics 47 card of your Indy.

Otherwise, the framebuffer console will 111 always select the first framebuffer driver that is loaded. The latter 112 is the default behavior. 113 114 You can always override the automatic selection of the primary device 115 by using the fbcon=map: boot option. 116 117 If unsure, select n. 118 119config FRAMEBUFFER_CONSOLE_ROTATION 120 bool "Framebuffer Console Rotation" 121 depends on FRAMEBUFFER_CONSOLE 122 help 123 Enable display rotation for the framebuffer console. This is done 124 in software and may be significantly slower than a normally oriented 125 display. Note that the rotation is done at the console level only 126 such that other users of the framebuffer will remain normally 127 oriented. 128 129config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER 130 bool "Framebuffer Console Deferred Takeover" 131 depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE 132 help 133 If enabled this defers the framebuffer console taking over the 134 console from the dummy console until the first text is displayed on 135 the console. This is useful in combination with the "quiet" kernel 136 commandline option to keep the framebuffer contents initially put up 137 by the firmware in place, rather then replacing the contents with a 138 black screen as soon as fbcon loads. 139 140config STI_CONSOLE 141 bool "STI text console" 142 depends on PARISC && HAS_IOMEM 143 select FONT_SUPPORT 144 select CRC32 145 select STI_CORE 146 default y 147 help 148 The STI console is the builtin display/keyboard on HP-PARISC 149 machines. Say Y here to build support for it into your kernel. 150 The alternative is to use your primary serial port as a console. 151 152endmenu 153 154
