.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

|
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 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.
