+
+.SH NAME
+vidcontrol - a utility for manipulating the syscons video driver.
+.SH SYNOPSIS
+.na
+.B vidcontrol
+.RB [options]
+.SH DESCRIPTION
+The
+.B vidcontrol
+command is used to set various options for the syscons video driver,
+such as video mode, colors, cursor, scrnmaps, font,
+screensaver type and timeout.
+
+A new video mode is selected by specifying its name as an argument to
+.B vidcontrol
+eg. "
+.B vidcontrol 80x25 
+". 
+
+The modes currently supported: 80x25 and 80x50 text.
+
+The colors used when displaying text can be changed by specifying the 
+foreground color (eg. "
+.B vidcontrol white
+"), or both a foreground & background
+color (eg. "
+.B vidcontrol yellow blue
+").
+
+To see the supported colors on a given platform use "
+.B vidcontrol show
+".
+
+.SH OPTIONS
+.TP
+The following command line options are supported.
+.TP
+.BI "\-r\ " foreground\ background
+Change reverse mode colors to
+.B foreground 
+and 
+.B background 
+.
+.TP
+.BI "\-b\ " color 
+Set border color to 
+.B color 
+(only supported on VGA hardware):
+.TP
+.BI "\-c\ " start.end
+Change the cursor apperance. The cursor is changed to a shape that starts
+on scanline 
+.B start
+and ends on scanline 
+.B end
+.
+.TP
+.BI "\-l\ " scrmap
+Install screen output map file from
+.I scrmap
+.TP
+.BI "\-L\ " 
+Install default screen output map.
+.TP
+.BI "\-f\ " size\ file
+Load font
+.I file
+for
+.I size
+(currently, only 8x8, 8x14 or 8x16).
+The fontfile can be either uuencoded or in raw binary format.
+.TP
+.BI "\-t\ " N|off
+Sets the screensaver timeout to
+.I N
+seconds, or turns it
+.I off
+.TP
+.BI "\-s\ " NAME|help
+Sets the screensaver appearance to
+.I NAME .
+Use \-s help to print a list of the available screen savers.
+.PP
