Allow fbcon to select the primary display adapter using the fb_is_primary_device() arch-specific helper. If a a primary adapter is detected, fbcon will unbind the old adapter from the VT layer, then rebind using the new adapter. This requires that bind_/unbind_con_driver() be made public. Because this feature may produce unexpected behavior (from the user's POV), this must be explicitly enabled in Kconfig.

Saying Y here will allow you to use Linux in text mode through a

display that complies with the generic VGA standard. Virtually

everyone wants that.
|

The program SVGATextMode can be used to utilize SVGA video cards to
|

their full potential in text mode. Download it from

<ftp://ibiblio.org/pub/Linux/utils/console/>.

help
|

The scrollback buffer of the standard VGA console is located in
|
|
the VGA RAM. The size of this RAM is fixed and is quite small.
|
|
If you require a larger scrollback buffer, this can be placed in
|
|
System RAM which is dynamically allocated during intialization.
|
|
Placing the scrollback buffer in System RAM will slightly slow
|
|
down the console.
|
|
|

If you want this feature, say 'Y' here and enter the amount of
|
|
RAM to allocate for this buffer. If unsure, say 'N'.

This enables support for text mode selection on kernel startup. If

you want to take advantage of some high-resolution text mode your

card's BIOS offers, but the traditional Linux utilities like
|
|
SVGATextMode don't, you can say Y here and set the mode using the
|
|
"vga=" option from your boot loader (lilo or loadlin) or set
|
|
"vga=ask" which brings up a video mode menu on kernel startup. (Try
|

"man bootparam" or see the documentation of your boot loader about
|

how to pass options to the kernel.)
