Video mode database:

-db <file>

set an alternative video mode database file (default is /etc/fb.modes), see also fb.modes(5)

Display geometry:

-xres <value>

set visible horizontal resolution (in pixels)

-yres <value>

set visible vertical resolution (in pixels)

-vxres <value>

set virtual horizontal resolution (in pixels)

-vyres <value>

set virtual vertical resolution (in pixels)

-depth <value>

set display depth (in bits per pixel)

--geometry, -g ...

set all geometry parameters at once in the order <xres> <yres> <vxres> <vyres> <depth>, e.g. -g 640 400 640 400 4

-match      

make the physical resolution match the virtual resolution

Display timings:

-pixclock <value>

set the length of one pixel (in picoseconds). Note that the frame buffer device may only support some pixel lengths

-left <value>

set left margin (in pixels)

-right <value>

set right margin (in pixels)

-upper <value>

set upper margin (in pixel lines)

-lower <value>

set lower margin (in pixel lines)

-hslen <value>

set horizontal sync length (in pixels)

-vslen <value>

set vertical sync length (in pixel lines)

--timings, -t ...

set all timing parameters at once in the order <pixclock> <left> <right> <upper> <lower> <hslen> <vslen>, e.g. -g 35242 64 96 35 12 112 2

Display flags:

-hsync {low|high}

set the horizontal sync polarity

-vsync {low|high}

set the vertical sync polarity

-csync {low|high}

set the composite sync polarity

-extsync {false|true}

enable or disable external resync. If enabled the sync timings are not generated by the frame buffer device and must be provided externally instead. Note that this option may not be supported by every frame buffer device

-bcast {false|true}

enable or disable broadcast modes. If enabled the frame buffer generates the exact timings for several broadcast modes (e.g. PAL or NTSC). Note that this option may not be supported by every frame buffer device

-laced {false|true}

enable or disable interlace. If enabled the display will be split in two frames, each frame contains only even and odd lines respectively. These two frames will be displayed alternating, this way twice the lines can be displayed and the vertical frequency for the monitor stays the same, but the visible vertical frequency gets halved

-double {false|true}

enable or disable doublescan. If enabled every line will be displayed twice and this way the horizontal frequency can easily be doubled, so that the same resolution can be displayed on different monitors, even if the horizontal frequency specification differs. Note that this option may not be supported by every frame buffer device

Display positioning:

-move {left|right|up|down}

move the visible part of the display in the specified direction

-step <value>

set step size for display positioning (in pixels or pixel lines), if -step is not given display will be moved 8 pixels horizontally or 2 pixel lines vertically

EXAMPLE

fbset -fb /dev/fb0 vga

export FRAMEBUFFER=/dev/fb0
