16 Saying Y here will allow you to use Linux in text mode through a
17 display that complies with the generic VGA standard. Virtually
20 The program SVGATextMode can be used to utilize SVGA video cards to
21 their full potential in text mode. Download it from

28 tristate "MDA text console (dual-headed)"
30 Say Y here if you have an old MDA or monochrome Hercules graphics
31 adapter in your system acting as a second head ( = video card). You
32 will then be able to use two monitors with your Linux system. Do not
33 say Y here if your MDA card is the primary card in your system; the
34 normal VGA driver will handle it.
36 To compile this driver as a module, choose M here: the
37 module will be called mdacon.
41 config SGI_NEWPORT_CONSOLE
42 tristate "SGI Newport Console support"
43 depends on SGI_IP22 && HAS_IOMEM
46 Say Y here if you want the console on the Newport aka XL graphics
47 card of your Indy. Most people say Y here.
53 config DUMMY_CONSOLE_COLUMNS
54 int "Initial number of console screen columns"
55 depends on DUMMY_CONSOLE && !ARM
59 On PA-RISC, the default value is 160, which should fit a 1280x1024
61 Select 80 if you use a 640x480 resolution by default.
63 config DUMMY_CONSOLE_ROWS
64 int "Initial number of console screen rows"
65 depends on DUMMY_CONSOLE && !ARM
69 On PA-RISC, the default value is 64, which should fit a 1280x1024
71 Select 25 if you use a 640x480 resolution by default.

74 bool "Framebuffer Console support"
75 depends on FB_CORE && !UML
76 select VT_HW_CONSOLE_BINDING
80 Low-level framebuffer-based console driver.
82 config FRAMEBUFFER_CONSOLE_LEGACY_ACCELERATION
83 bool "Enable legacy fbcon hardware acceleration code"
84 depends on FRAMEBUFFER_CONSOLE
88 This option enables the fbcon (framebuffer text-based) hardware
89 acceleration for graphics drivers which were written for the fbdev
92 On modern machines, on mainstream machines (like x86-64) or when
93 using a modern Linux distribution those fbdev drivers usually aren't used.
94 So enabling this option wouldn't have any effect, which is why you want
95 to disable this option on such newer machines.
97 If you compile this kernel for older machines which still require the
98 fbdev drivers, you may want to say Y.
102 config FRAMEBUFFER_CONSOLE_DETECT_PRIMARY
103 bool "Map the console to the primary display device"
104 depends on FRAMEBUFFER_CONSOLE
107 If this option is selected, the framebuffer console will
108 automatically select the primary display device (if the architecture
109 supports this feature). Otherwise, the framebuffer console will
110 always select the first framebuffer driver that is loaded. The latter
111 is the default behavior.
113 You can always override the automatic selection of the primary device
114 by using the fbcon=map: boot option.
118 config FRAMEBUFFER_CONSOLE_ROTATION
119 bool "Framebuffer Console Rotation"
120 depends on FRAMEBUFFER_CONSOLE
122 Enable display rotation for the framebuffer console. This is done
123 in software and may be significantly slower than a normally oriented
124 display. Note that the rotation is done at the console level only
125 such that other users of the framebuffer will remain normally
128 config FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER
129 bool "Framebuffer Console Deferred Takeover"
130 depends on FB=y && FRAMEBUFFER_CONSOLE && DUMMY_CONSOLE
132 If enabled this defers the framebuffer console taking over the
133 console from the dummy console until the first text is displayed on
134 the console. This is useful in combination with the "quiet" kernel
135 commandline option to keep the framebuffer contents initially put up
136 by the firmware in place, rather then replacing the contents with a
137 black screen as soon as fbcon loads.
140 bool "STI text console"
141 depends on PARISC && HAS_IOMEM
147 The STI console is the builtin display/keyboard on HP-PARISC
148 machines. Say Y here to build support for it into your kernel.
149 The alternative is to use your primary serial port as a console.
