Virtually 14 everyone wants that. 15 16 The program SVGATextMode can be used to utilize SVGA video cards to 17 their full potential in text mode. Download it from 18 <ftp://ibiblio.org/pub/Linux/utils/console/>. 19 20 Say Y. 21 22config VGACON_SOFT_SCROLLBACK 23 bool "Enable Scrollback Buffer in System RAM" 24 depends on VGA_CONSOLE 25 default n 26 help 27 The scrollback buffer of the standard VGA console is located in 28 the VGA RAM. The size of this RAM is fixed and is quite small. 29 If you require a larger scrollback buffer, this can be placed in 30 System RAM which is dynamically allocated during intialization. 31 Placing the scrollback buffer in System RAM will slightly slow 32 down the console. 33 34 If you want this feature, say 'Y' here and enter the amount of 35 RAM to allocate for this buffer. If unsure, say 'N'. 36 37config VGACON_SOFT_SCROLLBACK_SIZE 38 int "Scrollback Buffer Size (in KB)" 39 depends on VGACON_SOFT_SCROLLBACK 40 default "64" 41 help 42 Enter the amount of System RAM to allocate for the scrollback 43 buffer.

If 51 you want to take advantage of some high-resolution text mode your 52 card's BIOS offers, but the traditional Linux utilities like 53 SVGATextMode don't, you can say Y here and set the mode using the 54 "vga=" option from your boot loader (lilo or loadlin) or set 55 "vga=ask" which brings up a video mode menu on kernel startup. (Try 56 "man bootparam" or see the documentation of your boot loader about 57 how to pass options to the kernel.) 58 59 Read the file <file:Documentation/svga.txt> for more information 60 about the Video mode selection support.

You 68 will then be able to use two monitors with your Linux system. Do not 69 say Y here if your MDA card is the primary card in your system; the 70 normal VGA driver will handle it. 71 72 To compile this driver as a module, choose M here: the 73 module will be called mdacon. 74 75 If unsure, say N. 76 77config SGI_NEWPORT_CONSOLE 78 tristate "SGI Newport Console support" 79 depends on SGI_IP22 80 help 81 Say Y here if you want the console on the Newport aka XL graphics 82 card of your Indy.

This is done 126 in software and may be significantly slower than a normally oriented 127 display. Note that the rotation is done at the console level only 128 such that other users of the framebuffer will remain normally 129 oriented. 130 131config STI_CONSOLE 132 tristate "STI text console" 133 depends on PARISC 134 default y 135 help 136 The STI console is the builtin display/keyboard on HP-PARISC 137 machines.
