You can also use the menu-driven
|
||
.Xr vidfont 1
|
||
command to load the font of your choice.
|
||
.Pp
|
||
Note that older video cards, such as MDA and CGA, do not support
|

software font.

.Ss Video Mode Support
|
||
Note that not all modes listed above may be supported by the video
|
||
hardware.
|
||
You can verify which mode is supported by the video hardware, using the
|
||
.Fl i Cm mode
|
||
option.
|
||
.Pp
|
||
The VESA BIOS support must be linked to the kernel
|
||
or loaded as a KLD module if you wish to use VESA video modes
|
||
or 132 column modes
|
||
.Pq see Xr vga 4 .
|
||
.Pp
|
||
Video modes other than 25 and 30 line modes may require specific size of font.
|
||
Use
|
||
.Fl f
|
||
option above to load a font file to the kernel.
|
||
If the required size of font has not been loaded to the kernel,
|
||
.Nm
|
||
will fail if the user attempts to set a new video mode.

|
||
.Pp
|
||
It is better to always load all three sizes (8x8, 8x14 and 8x16)
|
||
of the same font.
|
||
.Pp
|
||
You may set variables in
|
||
.Pa /etc/rc.conf
|
||
or
|
||
.Pa /etc/rc.conf.local
|
||
so that desired font files will be automatically loaded
|
||
when the system starts up.
|
||
See below.
|
||
.Pp
|
||
If you want to use the raster text mode
|
||
.Ar VESA_800x600 ,
|
||
you need to recomile your kernel with the
|
||
.Em SC_PIXEL_MODE
|
||
option. See
|
||
.Xr syscons 4
|
||
for more details on this kernel option.
|
||
.Sh VIDEO OUTPUT CONFIGURATION
|
||
.Ss Boot Time Configuration
|
||
You may set the following variables in
|
||
.Pa /etc/rc.conf
|
||
or
|
||
.Pa /etc/rc.conf.local
|
||
in order to configure the video output at boot time.
|
||
.Pp
|
||
.Bl -tag -width foo_bar_var -compact
|
||
.It Ar blanktime
|
||
Sets the timeout value for the
|
||
.Fl t
|
||
option.
|
||
.It Ar font8x16 , font8x14 , font8x8
|
||
Specifies font files for the
|
||
.Fl f
|
||
option.
|
||
.It Ar scrnmap
|
||
Specifies a screen output map file for the
|
||
.Fl l
|
||
option.
|
||
.El
|
||
.Pp
|
||
See
|
||
.Xr rc.conf 5
|
||
for more details.
|
||
.Ss Driver Configuration
|
||
The video card driver may let you change default configuration
|
||
options, such as the default font, so that you do not need to set up
|
||
the options at boot time.
|
||
See video card driver manuals,
|
||
.Pq e.g. Xr vga 4
|
||
for details.
|
||
.Sh FILES
|
||
.Bl -tag -width /usr/share/syscons/scrnmaps/foo-bar -compact
|
||
.It Pa /usr/share/syscons/fonts/*
|
||
font files.
|
||
.It Pa /usr/share/syscons/scrnmaps/*
|
||
screen output map files.
|
||
.El
|
||
.Sh EXAMPLE
|
||
If you want to load
|
||
.Pa /usr/share/syscons/fonts/iso-8x16.fnt
|
||
to the kernel, run
|
||
.Nm
|
||
as:
|
||
.Pp
|
||
.Dl vidcontrol -f 8x16 /usr/share/syscons/fonts/iso-8x16.fnt
|
||
.Pp
|
||
So long as the font file is in
|
||
.Pa /usr/share/syscons/fonts ,
|
||
you may abbreviate the file name as
|
||
.Pa iso-8x16 :
|
||
.Pp
|
||
.Dl vidcontrol -f 8x16 iso-8x16
|
||
.Pp
|
||
Likewise, you can also abbreviate the screen output map file name for
|
||
the
|
||
.Fl l
|
||
option if the file is found in
|
||
.Pa /usr/share/syscons/scrnmaps .
|
||
.Pp
|
||
.Dl vidcontrol -l iso-8859-1_to_cp437
|
||
.Pp
|
||
The above command will load
|
||
.Pa /usr/share/syscons/scrnmaps/iso-8859-1_to_cp437.scm .
