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