12 | default y |
13 | help | |
14 | Saying Y here will allow you to use Linux in text mode through a | |
15 | display that complies with the generic VGA standard. Virtually | |
16 | everyone wants that. | |
17 | ||
18 | The program SVGATextMode can be used to utilize SVGA video cards to | |
19 | their full potential in text mode. Download it from | |
20 | <ftp://ibiblio.org/pub/Linux/utils/console/>. | |
21 | ||
22 | Say Y. | |

25 | bool "Enable Scrollback Buffer in System RAM" | |
26 | depends on VGA_CONSOLE | |
27 | default n | |
28 | help | |
29 | The scrollback buffer of the standard VGA console is located in | |
30 | the VGA RAM. The size of this RAM is fixed and is quite small. | |
31 | If you require a larger scrollback buffer, this can be placed in | |
01dd2fbf | 32 | System RAM which is dynamically allocated during initialization. |
15bdab95 AD |
33 | Placing the scrollback buffer in System RAM will slightly slow |
34 | down the console. | |
35 | ||
36 | If you want this feature, say 'Y' here and enter the amount of | |
37 | RAM to allocate for this buffer. If unsure, say 'N'. | |

45 | Enter the amount of System RAM to allocate for scrollback |
46 | buffers of VGA consoles. Each 64KB will give you approximately | |
47 | 16 80x25 screenfuls of scrollback buffer. | |

52 | default n | |
53 | help | |
1a336c93 MS |
54 | Say Y here if the scrollback history should persist by default when |
55 | switching between consoles. Otherwise, the scrollback history will be | |
56 | flushed each time the console is switched. This feature can also be | |
57 | enabled using the boot command line parameter | |
58 | 'vgacon.scrollback_persistent=1'. | |
aabd31c4 MS |
59 | |
60 | This feature might break your tool of choice to flush the scrollback | |
61 | buffer, e.g. clear(1) will work fine but Debian's clear_console(1) | |
62 | will be broken, which might cause security issues. | |
63 | You can use the escape sequence \e[3J instead if this feature is | |
64 | activated. | |
65 | ||
66 | Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each | |
67 | created tty device. | |
68 | So if you use a RAM-constrained system, say N here. | |

1da177e4 LT |
73 | ---help--- |
74 | Say Y here if you have an old MDA or monochrome Hercules graphics | |
75 | adapter in your system acting as a second head ( = video card). You | |
76 | will then be able to use two monitors with your Linux system. Do not | |
77 | say Y here if your MDA card is the primary card in your system; the | |
78 | normal VGA driver will handle it. | |
79 | ||
80 | To compile this driver as a module, choose M here: the | |
81 | module will be called mdacon. | |

132 | If this option is selected, the framebuffer console will | |

157 | If enabled this defers the framebuffer console taking over the | |
158 | console from the dummy console until the first text is displayed on | |
159 | the console. This is useful in combination with the "quiet" kernel | |
160 | commandline option to keep the framebuffer contents initially put up | |
161 | by the firmware in place, rather then replacing the contents with a | |
162 | black screen as soon as fbcon loads. | |
