Setting the right monitor size
Many
people
have
trouble
configuring
their
monitors
to
the
right
size
after
the
installation.
The
file
/lib/vgadb
contains
definitions
for
the
most
common
display
sizes
and
some
peculiar
hardware
that
Bell
Labs
or
other
9fans
have
used.
Once
you've
found
the
desirable
size,
set
monitor=
to
that
name
in
plan9.ini(8).
If
you
can't
find
an
appropriate
monitor
entry,
you
can
add
your
own
using
the
instructions
in
Adding
a
monitor
to
vgadb.
If
your
plan9.ini
file
isn't
located
in
/n/9fat/plan9.ini,
type
9fat:
For example, this entry is being typed on a T30 laptop with 1400x1050 display. The plan9.ini on this machine has the following entry:
monitor=t23
You can also change the resolution afterwards with aux/vga. Have a look at vga(8) for all details. In short:
aux/vga -m vesa -l 1280x1024x16
or
aux/vga -m vga -l
to reset the display to a known state.
Here's here is a list of some possible names for your display, for a complete list see /lib/vgadb:
