15 Saying Y here will allow you to use Linux in text mode through a
16 display that complies with the generic VGA standard. Virtually
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/>.

27 tristate "MDA text console (dual-headed)"
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.
35 To compile this driver as a module, choose M here: the
36 module will be called mdacon.
40 config SGI_NEWPORT_CONSOLE
41 tristate "SGI Newport Console support"
42 depends on SGI_IP22 && HAS_IOMEM
45 Say Y here if you want the console on the Newport aka XL graphics
46 card of your Indy. Most people say Y here.
52 config DUMMY_CONSOLE_COLUMNS
53 int "Initial number of console screen columns"
54 depends on DUMMY_CONSOLE && !ARM
58 On PA-RISC, the default value is 160, which should fit a 1280x1024
60 Select 80 if you use a 640x480 resolution by default.
62 config DUMMY_CONSOLE_ROWS
63 int "Initial number of console screen rows"
64 depends on DUMMY_CONSOLE && !ARM
68 On PA-RISC, the default value is 64, which should fit a 1280x1024
70 Select 25 if you use a 640x480 resolution by default.
72 config FRAMEBUFFER_CONSOLE
73 bool "Framebuffer Console support"
75 select VT_HW_CONSOLE_BINDING
79 Low-level framebuffer-based console driver.
81 config FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION
82 bool "Enable legacy fbcon hardware acceleration code"
83 depends on FRAMEBUFFER_CONSOLE
87 This option enables the fbcon (framebuffer text-based) hardware
88 acceleration for graphics drivers which were written for the fbdev
91 On modern machines, on mainstream machines (like x86-64) or when
92 using a modern Linux distribution those fbdev drivers usually aren't used.
93 So enabling this option wouldn't have any effect, which is why you want
94 to disable this option on such newer machines.
96 If you compile this kernel for older machines which still require the
97 fbdev drivers, you may want to say Y.
101 config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
102 bool "Map the console to the primary display device"
103 depends on FRAMEBUFFER_CONSOLE
106 If this option is selected, the framebuffer console will
107 automatically select the primary display device (if the architecture
108 supports this feature). Otherwise, the framebuffer console will
109 always select the first framebuffer driver that is loaded. The latter
110 is the default behavior.
112 You can always override the automatic selection of the primary device
113 by using the fbcon=map: boot option.
117 config FRAMEBUFFER_CONSOLE_ROTATION
118 bool "Framebuffer Console Rotation"
119 depends on FRAMEBUFFER_CONSOLE
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
127 config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER
128 bool "Framebuffer Console Deferred Takeover"
129 depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE
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.
139 bool "STI text console"
140 depends on PARISC && HAS_IOMEM
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.
