Virtually 17 everyone wants that. 18 19 The program SVGATextMode can be used to utilize SVGA video cards to 20 their full potential in text mode. Download it from 21 <ftp://ibiblio.org/pub/Linux/utils/console/>. 22 23 Say Y. 24 25config MDA_CONSOLE 26 depends on !M68K && !PARISC && ISA 27 tristate "MDA text console (dual-headed)" 28 help 29 Say Y here if you have an old MDA or monochrome Hercules graphics 30 adapter in your system acting as a second head ( = video card). You 31 will then be able to use two monitors with your Linux system. Do not 32 say Y here if your MDA card is the primary card in your system; the 33 normal VGA driver will handle it. 34 35 To compile this driver as a module, choose M here: the 36 module will be called mdacon. 37 38 If unsure, say N. 39 40config SGI_NEWPORT_CONSOLE 41 tristate "SGI Newport Console support" 42 depends on SGI_IP22 && HAS_IOMEM 43 select FONT_SUPPORT 44 help 45 Say Y here if you want the console on the Newport aka XL graphics 46 card of your Indy.

Otherwise, the framebuffer console will 109 always select the first framebuffer driver that is loaded. The latter 110 is the default behavior. 111 112 You can always override the automatic selection of the primary device 113 by using the fbcon=map: boot option. 114 115 If unsure, select n. 116 117config FRAMEBUFFER_CONSOLE_ROTATION 118 bool "Framebuffer Console Rotation" 119 depends on FRAMEBUFFER_CONSOLE 120 help 121 Enable display rotation for the framebuffer console. This is done 122 in software and may be significantly slower than a normally oriented 123 display. Note that the rotation is done at the console level only 124 such that other users of the framebuffer will remain normally 125 oriented. 126 127config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER 128 bool "Framebuffer Console Deferred Takeover" 129 depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE 130 help 131 If enabled this defers the framebuffer console taking over the 132 console from the dummy console until the first text is displayed on 133 the console. This is useful in combination with the "quiet" kernel 134 commandline option to keep the framebuffer contents initially put up 135 by the firmware in place, rather then replacing the contents with a 136 black screen as soon as fbcon loads. 137 138config STI_CONSOLE 139 bool "STI text console" 140 depends on PARISC && HAS_IOMEM 141 select FONT_SUPPORT 142 select CRC32 143 default y 144 help 145 The STI console is the builtin display/keyboard on HP-PARISC 146 machines. Say Y here to build support for it into your kernel. 147 The alternative is to use your primary serial port as a console. 148 149endmenu 150 151
