Virtually18 everyone wants that.19 20 The program SVGATextMode can be used to utilize SVGA video cards to21 their full potential in text mode.

You32 will then be able to use two monitors with your Linux system. Do not33 say Y here if your MDA card is the primary card in your system; the34 normal VGA driver will handle it.35 36 To compile this driver as a module, choose M here: the37 module will be called mdacon.38 39 If unsure, say N.40 41config SGI_NEWPORT_CONSOLE42 tristate "SGI Newport Console support"43 depends on SGI_IP22 && HAS_IOMEM44 select FONT_SUPPORT45 help46 Say Y here if you want the console on the Newport aka XL graphics47 card of your Indy.

Otherwise, the framebuffer console will112 always select the first framebuffer driver that is loaded. The latter113 is the default behavior.114 115 You can always override the automatic selection of the primary device116 by using the fbcon=map: boot option.117 118 If unsure, select n.119 120config FRAMEBUFFER_CONSOLE_ROTATION121 bool "Framebuffer Console Rotation"122 depends on FRAMEBUFFER_CONSOLE123 help124 Enable display rotation for the framebuffer console. This is done125 in software and may be significantly slower than a normally oriented126 display. Note that the rotation is done at the console level only127 such that other users of the framebuffer will remain normally128 oriented.129 130config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER131 bool "Framebuffer Console Deferred Takeover"132 depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE133 help134 If enabled this defers the framebuffer console taking over the135 console from the dummy console until the first text is displayed on136 the console. This is useful in combination with the "quiet" kernel137 commandline option to keep the framebuffer contents initially put up138 by the firmware in place, rather then replacing the contents with a139 black screen as soon as fbcon loads.140 141config STI_CONSOLE142 bool "STI text console"143 depends on PARISC && HAS_IOMEM144 select FONT_SUPPORT145 select CRC32146 select STI_CORE147 default y148 help149 The STI console is the builtin display/keyboard on HP-PARISC150 machines.
