Op flags Ar flags 57.Sh DESCRIPTION 58The 59.Nm 60driver provides multiple virtual terminals. 61It resembles the SCO color console driver. 62.Pp 63The 64.Nm 65driver is implemented on top of the keyboard driver 66.Pq Xr atkbd 4 67and the video card driver 68.Pq Xr vga 4 69and so requires both of them to be configured in the system. 70.Pp 71There can be only one 72.Nm 73device defined in the system. 74.Ss Virtual Terminals 75The 76.Nm 77driver provides multiple virtual terminals which appear as if they were 78separate terminals. 79One virtual terminal is considered current and exclusively 80occupies the screen and the keyboard; the other virtual terminals 81are placed in the background. 82.Pp 83In order to use virtual terminals, they must be individually 84marked ``on'' in 85.Pa /etc/ttys 86so that 87.Xr getty 8 88will recognize them to be active and run 89.Xr login 1 90to let the user log in to the system. 91By default, only the first eight virtual terminals are activated in 92.Pa /etc/ttys . 93.Pp 94You press the 95.Dv Alt 96key and a switch key to switch between 97virtual terminals. 98The following table summarizes the correspondence between the switch 99key and the virtual terminal. 100.Bd -literal -offset indent 101Alt-F1 ttyv0 Alt-F7 ttyv6 Shift-Alt-F1 ttyv10 102Alt-F2 ttyv1 Alt-F8 ttyv7 Shift-Alt-F2 ttyv11 103Alt-F3 ttyv2 Alt-F9 ttyv8 Shift-Alt-F3 ttyv12

key (usually the 110.Dv PrintScreen 111key on the AT Enhanced keyboard) to cycle available virtual terminals. 112.Pp 113The default number of available virtual terminals is 16. 114This can be changed with the kernel configuration option 115.Dv MAXCONS 116(see below). 117.Pp 118Note that the X server usually requires a virtual terminal for display 119purposes, so at least one terminal must be left unused by 120.Xr getty 8 121so that it can be used by the X server. 122.Ss Key Definitions and Function Key Strings 123The 124.Nm 125driver, in conjunction with the keyboard driver, allows the user 126to change key definitions and function key strings. 127The 128.Xr kbdcontrol 1 129command will load a key definition file (known as ``keymap'' file), 130dump the current keymap, and assign a string to a function key. 131See 132.Xr keyboard 4 133and 134.Xr kbdmap 5 135for the keymap file. 136.Pp 137You may want to set the 138.Ar keymap 139variable in 140.Pa /etc/rc.conf.local 141to the desired keymap file so that it will be automatically loaded 142when the system starts up. 143.Ss Software Font 144For most modern video cards, e.g. VGA, the 145.Nm 146driver and the video card driver allow the user to change 147the font used on the screen. 148The 149.Xr vidcontrol 1 150command can be used to load a font file from 151.Pa /usr/share/syscons/fonts . 152.Pp 153The font comes in various sizes: 8x8, 8x14 and 8x16. 154The 8x16 font is typically used for the VGA card in the 15580-column-by-25-line mode. 156Other video modes may require different font sizes. 157It is better to always load all three sizes of the same font. 158.Pp 159You may set 160.Ar font8x8 , 161.Ar font8x14 162and 163.Ar font8x16 164variables in 165.Pa /etc/rc.conf 166to the desired font files so that they will be automatically loaded 167when the system starts up. 168.Pp 169Optionally you can specify a particular font file as the default. 170See the 171.Dv SC_DFLT_FONT 172option below. 173.Ss Screen Map 174If your video card does not support software fonts, you may still be able 175to achieve a similar effect by re-mapping the font built into your video card. 176Use 177.Xr vidcontrol 1 178to load a screen map file which defines the mapping between character codes. 179.Ss Mouse Support and Copy-and-Paste 180You can use your mouse to copy text on the screen and paste it as if 181it was typed by hand. 182You must be running the mouse daemon 183.Xr moused 8 184and enable the mouse cursor in the virtual terminal via 185.Xr vidcontrol 1 . 186.Pp 187Pressing mouse button 1 (usually the left button) will start selection. 188Releasing button 1 will end the selection process. 189The selected text will be marked by inverting foreground and 190background colors. 191You can press button 3 (usually the right button) to extend 192the selected region. 193The selected text is placed in the copy buffer and can be pasted 194at the cursor position by pressing button 2 (usually the 195middle button) as many times as you like. 196.Pp 197If your mouse has only two buttons, you may want to use the 198.Dv SC_TWOBUTTON_MOUSE 199option below to make the right button to paste the text. 200Alternatively you can make the mouse daemon 201emulate the middle button. 202See the man page for 203.Xr moused 8 204for more details. 205.Ss Back Scrolling 206The 207.Nm 208driver allows the user to browse the output which has ``scrolled off'' 209the top of the screen. 210.Pp 211Press the ``slock'' key (usually 212.Dv ScrllLock 213/ 214.Dv Scroll Lock 215or 216.Dv Pause 217on many keyboards) and the terminal is 218in the ``scrollback'' mode. 219It is indicated by the 220.Dv Scroll Lock 221LED. 222Use the arrow keys, the 223.Dv Page Up/Down 224keys and the 225.Dv Home/End 226keys to scroll buffered terminal output. 227Press the ``slock'' key again to get back to the normal terminal mode. 228.Pp 229The size of the scrollback buffer can be set by the 230.Dv SC_HISTORY_SIZE 231option described below. 232.Ss Screen Saver 233The 234.Nm 235driver can be made to put up the screen saver if the current 236virtual terminal is idle, that is, the user is not typing 237on the keyboard nor moving the mouse. 238See 239.Xr splash 4 240and 241.Xr vidcontrol 1 242for more details. 243.Sh DRIVER CONFIGURATION 244.Ss Kernel Configuration Options 245The following kernel configuration options control the 246.Nm 247driver. 248.Bl -tag -width MOUSE 249.It Dv MAXCONS=N 250This option sets the number of virtual terminals to 251.Fa N . 252The default value is 16. 253.It Dv SC_ALT_MOUSE_IMAGE 254This option selects the alternative way of displaying the mouse cursor 255in the virtual terminal. 256It may be expensive for some video cards to draw the arrow-shaped 257cursor, and you may want to try this option. 258However, the appearance of the alternative mouse cursor may not be 259very appealing. 260Note that if you use the 261.Dv SC_NO_FONT_LOADING 262option then you must also use this option if you wish to be able to use 263the mouse. 264.It Dv SC_DISABLE_DDBKEY 265This option disables the ``debug'' key combination (by default, it is 266.Dv Alt-Esc , 267or 268.Dv Ctl-PrintScreen ) . 269It will prevent users from 270entering the kernel debugger (DDB) by pressing the key combination. 271DDB will still be invoked when the kernel panics or hits a break point 272if it is included in the kernel. 273.It Dv SC_DISABLE_REBOOT 274This option disables the ``reboot'' key (by default, it is 275.Dv Ctl-Alt-Del ) , 276so that the casual user may not accidentally reboot the system. 277.It Dv SC_HISTORY_SIZE=N 278Sets the size of back scroll buffer to 279.Fa N 280lines. 281The default value is 100. 282.It Dv SC_MOUSE_CHAR=C 283Unless the 284.Dv SC_ALT_MOUSE_IMAGE 285option above is specified, the 286.Nm 287driver reserves four consecutive character codes in order to display the 288mouse cursor in the virtual terminals in some systems. 289This option specifies the first character code to 290.Fa C 291to be used for this purpose. 292The default value is 0xd0. 293A good candidate is 0x03. 294.It Dv SC_PIXEL_MODE 295Adds support for pixel (raster) mode console. 296This mode is useful on some laptop computers, but less so on 297most other systems, and it adds substantial amount of code to 298.Nm . 299If this option is NOT defined, you can reduce the kernel size a lot. 300See the 301.Dv VESA800X600 302flag below. 303.It Dv SC_TWOBUTTON_MOUSE 304If you have a two button mouse, you may want to add this option 305to use the right button of the mouse to paste text. 306See 307.Sx Mouse Support and Copy-and-Paste 308above. 309.It Dv SC_NORM_ATTR=_attribute_ 310.It Dv SC_NORM_REV_ATTR=_attribute_ 311.It Dv SC_KERNEL_CONS_ATTR=_attribute_ 312.It Dv SC_KERNEL_CONS_REV_ATTR=_attribute_ 313These options will set the default colors. 314Available colors are defined in 315.In machine/pc/display.h . 316See 317.Sx EXAMPLES 318below. 319.It Dv SC_DFLT_FONT 320This option will specify the default font. 321Available fonts are: iso, iso2, koi8-r, koi8-u, cp437, cp850, cp865, 322cp866 and cp866u. 32316-line, 14-line and 8-line font data will be compiled in. 324Without this option, the 325.Nm 326driver will use whatever font is already loaded in the video card, 327unless you explicitly load a software font at startup. 328See 329.Sx EXAMPLES 330below. 331.El 332.Pp 333The following options will remove some features from the 334.Nm 335driver and save kernel memory. 336.Bl -tag -width MOUSE 337.It Dv SC_NO_CUTPASTE 338This option disables ``copy and paste'' operation in virtual 339terminals. 340.It Dv SC_NO_FONT_LOADING 341The 342.Nm 343driver can load software fonts on some video cards. 344This option removes this feature. 345Note that if you still wish to use 346the mouse with this option then you must also use the 347.Dv SC_ALT_MOUSE_IMAGE 348option. 349.It Dv SC_NO_HISTORY 350This option disables back-scrolling in virtual terminals. 351.\".It Dv SC_NO_PALETTE_LOADING 352.It Dv SC_NO_SYSMOUSE 353This option removes mouse support in the 354.Nm 355driver. 356The mouse daemon 357.Xr moused 8 358will fail if this option is defined. 359This option implies the 360.Dv SC_NO_CUTPASTE 361option too. 362.El 363.Ss Driver Flags 364The following driver flags can be used to control the 365.Nm 366driver. 367They can be set either in the kernel configuration file 368(see 369.Xr config 8 ) , 370or else in the User Configuration Menu at boot 371time 372(see 373.Xr boot 8 ) . 374.Bl -tag -width bit_0 375.\".It bit 0 (VISUAL_BELL) 376.\"Uses the ``visual'' bell. 377.\"The screen will blink instead of generating audible sound. 378.\".It bit 1,2 (CURSOR_TYPE) 379.\"This option specifies the cursor appearance. 380.\"Possible values are: 381.\".Bl -tag -width TYPE -compact 382.\".It Dv 0 383.\"normal block cursor 384.\".It Dv 2 385.\"blinking block cursor 386.\".It Dv 4 387.\"underline cursor 388.\".It Dv 6 389.\"blinking underline (aka destructive) cursor 390.\".El 391.\".It bit 6 (QUIET_BELL) 392.\"This option suppresses the bell, whether audible or visual, 393.\"if it is rung in a background virtual terminal. 394.It 0x0080 (VESA800X600) 395This option puts the video card in the VESA 800x600 pixel, 16 color 396mode. 397It may be useful for laptop computers for which the 800x600 mode 398is otherwise unsupported by the X server. 399Note that in order for this flag to work, the kernel must be 400compiled with the 401.Dv SC_PIXEL_MODE 402option explained above. 403.\"Note also that the ``copy-and-paste'' function is not currently supported 404.\"in this mode and the mouse pointer will not be displayed. 405.It 0x0100 (AUTODETECT_KBD) 406This option instructs the 407.Nm 408driver to periodically scan 409for a keyboard device if it is not currently attached to one. 410Otherwise, the driver only probes for a keyboard once during bootup. 411.El 412.Sh IOCTLS 413The following 414.Xr ioctl 2 415commands are defined for the 416.Nm 417driver in 418.In sys/consio.h . 419.Pp 420.Bl -tag -width CONS -compact 421.It Dv KDGETMODE Ar int *mode 422.It Dv KDSETMODE Ar int *mode 423Get or set the mode of the
