DESCRIPTION

       Xrandr is used to set the size, orientation and/or  reflection  of  the
       outputs for a screen. It can also set the screen size.

       If  invoked  without any option, it will dump the state of the outputs,
       showing the existing modes for each of  them,  with  a  ’+’  after  the
       preferred mode and a ’*’ after the current mode.

       There  are  a  few global options. Other options modify the last output
       that is specified in earlier parameters in the command  line.  Multiple
       outputs  may  be modified at the same time by passing multiple --output
       options followed immediately by their corresponding modifying  options.

       -help  Print out a summary of the usage and exit.

       -v, --version
              Print out the RandR version reported by the X server and exit.

       --verbose
              Causes  xrandr to be more verbose. When used with -q (or without
              other options), xrandr will display more information  about  the
              server  state. When used along with options that reconfigure the
              system,  progress  will  be   reported   while   executing   the
              configuration changes.

       -q, --query
              When  this  option  is present, or when no configuration changes
              are requested, xrandr will display  the  current  state  of  the
              system.

       --dryrun
              Performs  all  the  actions specified except that no changes are
              made.

       -d, -display name
              This option selects the X display to use. Note  this  refers  to
              the X screen abstraction, not the monitor (or output).

       --screen snum
              This option selects which screen to manipulate. Note this refers
              to the X screen abstraction, not the monitor (or output).

       --q1   Forces the usage of the RandR version 1.1 protocol,  even  if  a
              higher version is available.

       --q12  Forces  the usage of the RandR version 1.2 protocol, even if the
              display does not report it as supported or a higher  version  is
              available.

RandR version 1.3 options

       Options  for  RandR 1.3 are used as a superset of the options for RandR
       1.2.

       --current
              Return the current screen  configuration,  without  polling  for
              hardware changes.

       --noprimary
              Don’t define a primary output.

       Per-output options

       --panning
       widthxheight[+x+y[/track_widthxtrack_height+track_x+track_y[/border_left/border_top/border_right/border_bottom]]]
              This  option sets the panning parameters.  As soon as panning is
              enabled, the CRTC position can change with every  pointer  move.
              The  first  four  parameters specify the total panning area, the
              next four the pointer tracking area (which defaults to the  same
              area).  The  last four parameters specify the border and default
              to 0. A width or height set to  zero  disables  panning  on  the
              according  axis.  You typically have to set the screen size with
              --fb simultaneously.

       --transform a,b,c,d,e,f,g,h,i
              Specifies a  transformation  matrix  to  apply  on  the  output.
              Automatically  a  bilinear filter is selected.  The mathematical
              form corresponds to:
                     a b c
                     d e f
                     g h i
              The transformation matrix multiplied by a coordinate vector of a
              pixel of the output (extended to 3 values) gives the approximate
              coordinate vector of a pixel in the graphic buffer. Typically, a
              and  e  corresponds  to the scaling on the X and Y axes, c and f
              corresponds to the tranlastion on those axes, and g,  h,  and  i
              are  respectively  0,  0  and  1.  It  also  allows to express a
              rotation of an angle T with:
                     cos T  -sin T   0
                     sin T   cos T   0
                      0       0      1
              As a special argument, instead of passing a matrix, one can pass
              the  string  none,  in which case the default values are used (a
              unit matrix without filter).

              --scale xxy
                     Changes the dimensions  of  the  output  picture.  Values
                     superior  to  1  will lead to a compressed screen (screen
                     dimension bigger than the dimension of the output  mode),
                     and values below 1 leads to a zoom in on the output. This
                     option is actually a shortcut version of the  --transform
                     option.

              --primary
                     Set  the  output  as primary.  It will be sorted first in
                     Xinerama and RANDR geometry requests.

RandR version 1.2 options

       These options are only available for X server supporting RandR  version
       1.2 or newer.

       --prop, --properties
              This  option causes xrandr to display the contents of properties
              for each output. --verbose also enables --prop.

       --fb widthxheight
              Reconfigures the screen to the specified  size.  All  configured
              monitors  must  fit  within  this  size. When this option is not
              provided, xrandr computes the smallest  screen  size  that  will
              hold  the  set of configured outputs; this option provides a way
              to override that behaviour.

       --fbmm widthxheight
              Sets the reported values for the physical size  of  the  screen.
              Normally,  xrandr  resets  the  reported physical size values to
              keep the DPI constant.  This overrides that computation.

       --dpi dpi
              This also sets the reported physical size values of the  screen,
              it  uses  the  specified  DPI  value  to  compute an appropriate
              physical size using whatever pixel size will be set.

       --newmode name mode
              New modelines can be added to the  server  and  then  associated
              with  outputs.   This  option  does  the  former.  The  mode  is
              specified  using  the  ModeLine  syntax  for  xorg.conf:   hdisp
              hsyncstart  hsyncend  htotal  vdisp  vsyncstart  vsyncend vtotal
              flags. flags can be zero or  more  of  +HSync,  -HSync,  +VSync,
              -VSync,  Interlace,  DoubleScan,  CSync, +CSync, -CSync. Several
              tools permit to compute the usual modeline from a height, width,
              and refresh rate, for instance you can use cvt.

       --rmmode name
              This removes a mode from the server if it is otherwise unused.

       --addmode output name
              Add a mode to the set of valid modes for an output.

       --delmode output name
              Remove a mode from the set of valid modes for an output.

       Per-output options

       --output output
              Selects  an  output  to  reconfigure. Use either the name of the
              output or the XID.

       --auto For connected but disabled outputs, this will enable them  using
              their  preferred mode (or, something close to 96dpi if they have
              no preferred mode). For disconnected but enabled  outputs,  this
              will disable them.

       --mode mode
              This selects a mode. Use either the name or the XID for mode

       --preferred
              This   selects   the   same  mode  as  --auto,  but  it  doesn’t
              automatically enable or disable the output.

       --pos xxy
              Position the output within the screen using  pixel  coordinates.
              In  case  reflection  or rotation is applied, the translation is
              applied after the effects.

       --rate rate
              This marks a preference for refresh rates close to the specified
              value,  when multiple modes have the same name, this will select
              the one with the nearest refresh rate.

       --reflect reflection
              Reflection can be one of ’normal’ ’x’, ’y’ or ’xy’. This  causes
              the output contents to be reflected across the specified axes.

       --rotate rotation
              Rotation  can be one of ’normal’, ’left’, ’right’ or ’inverted’.
              This causes the output contents to be rotated in  the  specified
              direction. ’right’ specifies a clockwise rotation of the picture
              and ’left’ specifies a counter-clockwise rotation.

       --left-of, --right-of, --above, --below, --same-as another-output
              Use one of these options to position the output relative to  the
              position  of  another  output.  This allows convenient tiling of
              outputs within the screen.   The  position  is  always  computed
              relative  to  the new position of the other output, so it is not
              valid to say --output a --left-of b --output b --left-of a.

       --set property value
              Sets an output property. Integer properties may be specified  as
              a  valid (see --prop) decimal or hexadecimal (with a leading 0x)
              value. Atom properties may be set to any of the valid atoms (see
              --prop). String properties may be set to any value.

       --off  Disables the output.

       --crtc crtc
              Uses the specified crtc (either as an index in the list of CRTCs
              or XID).  In normal usage, this option is not required as xrandr
              tries to make sensible choices about which crtc to use with each
              output. When  that  fails  for  some  reason,  this  option  can
              override the normal selection.

       --gamma red:green:blue
              Set  the  specified floating point values as gamma correction on
              the crtc currently attached to this output. Note that you cannot
              get  two  different values for cloned outputs and that switching
              an  output  to  another  crtc  doesn’t  change  the  crtc  gamma
              corrections at all.

RandR version 1.1 options

       These  options are available for X servers supporting RandR version 1.1
       or older. They are still valid for newer  X  servers,  but  they  don’t
       interact sensibly with version 1.2 options on the same command line.

       -s, --size size-index or --size widthxheight
              This  sets the screen size, either matching by size or using the
              index into the list of available sizes.

       -r, --rate, --refresh rate
              This sets the refresh rate closest to the specified value.

       -o, --orientation rotation
              This specifies the orientation of the screen, and can be one  of
              normal, inverted, left or right.

       -x     Reflect across the X axis.

       -y     Reflect across the Y axis.

EXAMPLES

       Sets  an output called LVDS to its preferred mode, and on its right put
       an output called VGA to preferred mode  of  a  screen  which  has  been
       physically rotated clockwise:
              xrandr  --output  LVDS --auto --rotate normal --pos 0x0 --output
              VGA --auto --rotate left --right-of LVDS

       Forces to use a 1024x768 mode on an output called VGA:
              xrandr --newmode "1024x768" 63.50  1024 1072 1176 1328  768  771
              775 798 -hsync +vsync
              xrandr --addmode VGA 1024x768
              xrandr --output VGA --mode 1024x768

       Enables panning on a 1600x768 desktop while displaying 1024x768 mode on
       an output called VGA:
              xrandr --fb 1600x768  --output  VGA  --mode  1024x768  --panning
              1600x0

       Have  one  small 1280x800 LVDS screen showing a small version of a huge
       3200x2000 desktop, and have a big VGA screen display the surrounding of
       the mouse at normal size.
              xrandr --fb 3200x2000 --output LVDS --scale 2.5x2.5 --output VGA
              --pos 0x0 --panning 3200x2000+0+0/3200x2000+0+0/64/64/64/64
