.SH DESCRIPTION
|
|
.I 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.
|
|
.IP \-help
|
|
Print out a summary of the usage and exit.
|
|
.IP "\-v, \-\-version"
|
|
Print out the RandR version reported by the X server and exit.
|
|
.IP \-\-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.
|
|
.IP "\-q, \-\-query"
|
|
When this option is present, or when no configuration changes are requested,
|
|
xrandr will display the current state of the system.
|
|
.IP "\-\-dryrun"
|
|
Performs all the actions specified except that no changes are made.
|
|
.IP "\-\-nograb"
|
|
Apply the modifications without grabbing the screen. It avoids to block other
|
|
applications during the update but it might also cause some applications that
|
|
detect screen resize to receive old values.
|
|
.IP "\-d, \-display \fIname\fP"
|
|
This option selects the X display to use. Note this refers to the X
|
|
screen abstraction, not the monitor (or output).
|
|
.IP "\-\-screen \fIsnum\fP"
|
|
This option selects which screen to manipulate. Note this refers to the X
|
|
screen abstraction, not the monitor (or output).
|
|
.IP \-\-q1
|
|
Forces the usage of the RandR version 1.1 protocol, even if a higher version
|
|
is available.
|
|
.IP \-\-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.
|
|
.PP
|
|
.SH "RandR version 1.3 options"
|
|
.PP
|
|
Options for RandR 1.3 are used as a superset of the options for RandR 1.2.
|
|
.PP
|
|
.IP \-\-current
|
|
Return the current screen configuration, without polling for hardware changes.
|
|
.IP \-\-noprimary
|
|
Don't define a primary output.
|
|
.PP
|
|
.B "Per-output options"
|
|
.IP "\-\-panning \fIwidth\fPx\fIheight\fP[+\fIx\fP+\fIy\fP[/\fItrack_width\fPx\fItrack_height\fP+\fItrack_x\fP+\fItrack_y\fP[/\fIborder_left\fP/\fIborder_top\fP/\fIborder_right\fP/\fIborder_bottom\fP]]]"
|
|
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 \fI--fb\fP simultaneously.
|
|
.IP "\-\-transform \fIa\fP,\fIb\fP,\fIc\fP,\fId\fP,\fIe\fP,\fIf\fP,\fIg\fP,\fIh\fP,\fIi\fP"
|
|
Specifies a transformation matrix to apply on the output. Automatically a bilinear filter is selected.
|
|
The mathematical form corresponds to:
|
|

.RE
|
|
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, \fIa\fP and
|
|
\fIe\fP corresponds to the scaling on the X and Y axes, \fIc\fP and \fIf\fP
|
|
corresponds to the tranlastion on those axes, and \fIg\fP, \fIh\fP, and \fIi\fP
|
|
are respectively 0, 0 and 1. It also allows to express a rotation of an angle T
|
|
with:
|
|
.RS
|
|
cos T -sin T 0
|
|
.br
|
|
sin T cos T 0
|
|

|
|

|
|
.RE
|
|
As a special argument, instead of
|
|
passing a matrix, one can pass the string \fInone\fP, in which case the default
|
|
values are used (a unit matrix without filter).
|
|
.RE
|
|
.IP "\-\-scale \fIx\fPx\fIy\fP"
|
|
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 \fI\-\-transform\fP option.
|
|
.IP \-\-primary
|
|
Set the output as primary.
|
|
It will be sorted first in Xinerama and RANDR geometry requests.
|
|
.PP
|
|
.SH "RandR version 1.2 options"
|
|
These options are only available for X server supporting RandR version 1.2
|
|
or newer.
|
|
.IP "\-\-prop, \-\-properties"
|
|
This option causes xrandr to display the contents of properties for each
|
|
output. \-\-verbose also enables \-\-prop.
|
|
.IP "\-\-fb \fIwidth\fPx\fIheight\fP"
|
|
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.
|
|
.IP "\-\-fbmm \fIwidth\fPx\fIheight\fP"
|
|
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.
|
|
.IP "\-\-dpi \fIdpi\fP"
|
|
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.
|
|
.IP "\-\-newmode \fIname\fP \fImode\fP"
|
|
New modelines can be added to the server and then associated with outputs.
|
|
This option does the former. The \fImode\fP is specified using the ModeLine
|
|
syntax for xorg.conf: hdisp hsyncstart hsyncend htotal vdisp vsyncstart
|
|
vsyncend vtotal \fIflags\fP. \fIflags\fP 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 \fBcvt\fR.
|
|
.IP "\-\-rmmode \fIname\fP"
|
|
This removes a mode from the server if it is otherwise unused.
|
|
.IP "\-\-addmode \fIoutput\fP \fIname\fP"
|
|
Add a mode to the set of valid modes for an output.
|
|
.IP "\-\-delmode \fIoutput\fP \fIname\fP"
|
|
Remove a mode from the set of valid modes for an output.
|
|
.PP
|
|
.B "Per-output options"
|
|
.IP "\-\-output \fIoutput\fP"
|
|
Selects an output to reconfigure. Use either the name of the output or the
|
|
XID.
|
|
.IP \-\-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.
|
|
.IP "\-\-mode \fImode\fP"
|
|
This selects a mode. Use either the name or the XID for \fImode\fP
|
|
.IP "\-\-preferred"
|
|
This selects the same mode as \-\-auto, but it doesn't automatically enable or
|
|
disable the output.
|
|
.IP "\-\-pos \fIx\fPx\fIy\fP"
|
|
Position the output within the screen using pixel coordinates. In case reflection
|
|
or rotation is applied, the translation is applied after the effects.
|
|
.IP "\-\-rate \fIrate\fP"
|
|
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.
|
|
.IP "\-\-reflect \fIreflection\fP"
|
|
Reflection can be one of 'normal' 'x', 'y' or 'xy'. This causes the output
|
|
contents to be reflected across the specified axes.
|
|
.IP "\-\-rotate \fIrotation\fP"
|
|
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.
|
|
.IP "\-\-left\-of, \-\-right\-of, \-\-above, \-\-below, \-\-same-as \fIanother-output\fP"
|
|
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.
|
|
.IP "\-\-set \fIproperty\fP \fIvalue\fP"
|
|
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.
|
|
.IP "\-\-off"
|
|
Disables the output.
|
|
.IP "\-\-crtc \fIcrtc\fP"
|
|
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.
|
|
.IP "\-\-gamma \fIred\fP:\fIgreen\fP:\fIblue\fP"
|
|
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.
|
|
.PP
|
|
.SH "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.
|
|
.IP "\-s, \-\-size \fIsize-index\fP or \-\-size \fIwidth\fPx\fIheight\fP"
|
|
This sets the screen size, either matching by size or using the index into
|
|
the list of available sizes.
|
|
.IP "\-r, \-\-rate, \-\-refresh \fIrate\fP"
|
|
This sets the refresh rate closest to the specified value.
|
|
.IP "\-o, \-\-orientation \fIrotation\fP"
|
|
This specifies the orientation of the screen,
|
|
and can be one of normal, inverted, left or right.
|
|
.IP \-x
|
|
Reflect across the X axis.
|
|
.IP \-y
|
|
Reflect across the Y axis.
|
|
