.Os
.Sh NAME
.Nm videomode
.Nd initial graphics resolution
.Sh SYNOPSIS
.Nm /etc/videomode
.Sh DESCRIPTION
The
.Nm videomode
file is read on boot by
.Xr init 8
and is used as the initial graphics resolution on the primary monitor. The
resolution provided by the bootloader remains in effect if the file is missing.
The resolution is usable only if the graphics card has a driver and the
resolution is supported.
.Sh FORMAT
.Ar width Ns x Ns Ar height Ns x Ns Ar bits-per-pixel
.Pp
The file specifies a graphics resolution as a single line with three numeric
fields separated by x characters and no whitespace whatsoever. The first field
is used as the
.Ar width
in pixels, the second field is used as the
.Ar height
in pixels, and the third field is used as the
.Ar bits-per-pixel .
.Sh FILES

.Sh BUGS
This scheme only supports a single monitor. The kernel console doesn't handle
resolution changes gracefully, the console will be cleared and the console
cursor might be out of the screen upon resolution shrink. Early boot messages
will be unavailable.
