Console size and scrollback buffer.
Hello List,
[On FreeBSD 7.1-BETA2, i386.]
1) How can I change the number of rowsxcols of the console? I'd like
to use the maximum rows/cols available for the 1440x900 screen.
2) How can these settings be made default (takes effect at boot)?
IOW, what is the equivalent of the vga=0x365 Linux kernel option?
3) How I can set the scrollback buffer size (if that's the name) of
the console -- the equivalent of Shift+{PgUp,PgDn} on Linux?
I played around with vidcontrol but was not quite successful.
Thanks in advance.
-James.

You can use vidcontrol to do that.

At boot? Never tried this, but I think there are some kernel
settings that are relevant for this; they'll be documented in
the NOTES files for the kernel.

In FreeBSD, use the Scroll Lock key (that's why it's there); the
length of the scrollback buffer can be controlled by vidcontrol, too.
Refer to man vidcontrol and its EXAMPLES section.

Make sure the requested videomode is available, vidcontrol -i mode
will tell you.

try adding this in /etc/rc.conf
vidcontrol -h 200
# -h = Set the size of the history scrollback buffer in number of lines.

Re: Console size and scrollback buffer.
i think it can be done somehow, but isn't the best to run X on your card
with 1440x900 resolution and run one (or several) xterms full screen.
that's what i do with fvwm2 window manager and slightly modified config.
no window frames, no titlebars, buttons etc, 100% screen for program, not
only xterm

In order to use graphical VESA modes you need a custom kernel that
includes these options:
options VESA
options SC_PIXEL_MODE
You will only be able to use a 1440x900 resolution if your video hardware
advertises that as a standard VESA mode. Once you are running a kernel
with the above options you can use vidcontrol to list the available
options:
vidcontrol -i mode
When you see a mode you like you can switch to it using vidcontrol again.
For example:
vidcontrol MODE_XX -f 8x8 cp437-8x8.fnt
Replace XX with the number of the mode you'd like to use. Adjust the
arguments to -f to suit your needs. Other sizes are 8x14 and 8x16. You
should choose a font to match the specified size and the character set
you're using. See the manpage for vidcontrol for greater detail.
With a standard kernel you can use text modes like 80x50 or even 80x60
to get more rows than the standard 80x25. e.g:
vidcontrol -f 8x8 cp437-8x8.fnt VGA_80x60
2) How can these settings be made default (takes effect at boot)?
IOW, what is the equivalent of the vga=0x365 Linux kernel option?
Use the allscreens_flags option in rc.conf. For the text example above
you'd want:
allscreens_flags=-f 8x8 cp437-8x8.fnt VGA_80x60
Similarly for graphics modes, just include everything you'd include on the
command line to vidcontrol.
3) How I can set the scrollback buffer size (if that's the name) of
the console -- the equivalent of Shift+{PgUp,PgDn} on Linux?
I usually do this via the SC_HISTORY_SIZE kernel option. Scroll-lock can
be used to browse the history in any console virtual terminal.
See the sc(4) manpage for details on this option and the SC_PIXEL_MODE
option mentioned above.
