Logic that obtains current DPMS state is put inside the handler. sway_output from which the current DPMS state will be obtained is selected by the following logic: * For '-' and '--' the focused output is used; * For '*' error "Cannot apply toggle to all outputs" is reported; * For everything else all_output_by_name_or_id() is used. Fixes #5929.

# NAME
|
|
|
|
sway-output - output configuration commands for sway
|
|
|
|
# DESCRIPTION
|
|
|
|
You may combine output commands into one, like so:
|
|
|
|
output HDMI-A-1 mode 1920x1080 pos 1920 0 bg ~/wallpaper.png stretch
|
|
|
|
You can get a list of output names with *swaymsg -t get_outputs*. You may also
|
|
match any output by using the output name "\*". Additionally, "-" can be used
|
|
to match the focused output by name and "--" can be used to match the focused
|
|
output by its identifier.
|
|
|
|
Some outputs may have different names when disconnecting and reconnecting. To
|
|
identify these, the name can be substituted for a string consisting of the make,
|
|
model and serial which you can get from *swaymsg -t get_outputs*. Each value
|
|
must be separated by one space. For example:
|
|
|
|
output "Some Company ABC123 0x00000000" pos 1920 0
|
|
|
|
# COMMANDS
|
|
|
|
*output* <name> mode|resolution|res [--custom] <WIDTHxHEIGHT>[@<RATE>Hz]
|
|
Configures the specified output to use the given mode. Modes are a
|
|
combination of width and height (in pixels) and a refresh rate that your
|
|
display can be configured to use. For a list of available modes for each
|
|
output, use *swaymsg -t get_outputs*.
|
|
|
|
To set a custom mode not listed in the list of available modes, use
|
|
*--custom*. You should probably only use this if you know what you're
|
|
doing.
|
|
|
|
Examples:
|
|
|
|
output HDMI-A-1 mode 1920x1080
|
|
|
|
output HDMI-A-1 mode 1920x1080@60Hz
|
|
|
|
*output* <name> position|pos <X> <Y>
|
|
Places the specified output at the specific position in the global
|
|
coordinate space. The cursor may only be moved between immediately
|
|
adjacent outputs. If scaling is active, it has to be considered when
|
|
positioning. For example, if the scaling factor for the left output is
|
|
2, the relative position for the right output has to be divided by 2.
|
|
The reference point is the top left corner so if you want the bottoms
|
|
aligned this has to be considered as well.
|
|
|
|
Example:
|
|
|
|
output HDMI1 scale 2
|
|
|
|
output HDMI1 pos 0 1020 res 3200x1800
|
|
|
|
output eDP1 pos 1600 0 res 1920x1080
|
|
|
|
Note that the left x-pos of eDP1 is 1600 = 3200/2 and the bottom y-pos is
|
|
1020 + (1800 / 2) = 1920 = 0 + 1920
|
|
|
|
*output* <name> scale <factor>
|
|
Scales the specified output by the specified scale _factor_. An integer is
|
|
recommended, but fractional values are also supported. If a fractional
|
|
value are specified, be warned that it is not possible to faithfully
|
|
represent the contents of your windows - they will be rendered at the next
|
|
highest integer scale factor and downscaled. You may be better served by
|
|
setting an integer scale factor and adjusting the font size of your
|
|
applications to taste. HiDPI isn't supported with Xwayland clients (windows
|
|
will blur).
|
|
|
|
*output* <name> scale_filter linear|nearest|smart
|
|
Indicates how to scale application buffers that are rendered at a scale
|
|
lower than the output's configured scale, such as lo-dpi applications on
|
|
hi-dpi screens. Linear is smoother and blurrier, nearest (also known as
|
|
nearest neighbor) is sharper and blockier. Setting "smart" will apply
|
|
nearest scaling when the output has an integer scale factor, otherwise
|
|
linear. The default is "smart".
|
|
|
|
*output* <name> subpixel rgb|bgr|vrgb|vbgr|none
|
|
Manually sets the subpixel hinting for the specified output. This value is
|
|
usually auto-detected, but some displays may misreport their subpixel
|
|
geometry. Using the correct subpixel hinting allows for sharper text.
|
|
Incorrect values will result in blurrier text. When changing this via
|
|
*swaymsg*, some applications may need to be restarted to use the new value.
|
|
|
|
*output* <name> background|bg <file> <mode> [<fallback_color>]
|
|
Sets the wallpaper for the given output to the specified file, using the
|
|
given scaling mode (one of "stretch", "fill", "fit", "center", "tile"). If
|
|
the specified file cannot be accessed or if the image does not fill the entire
|
|
output, a fallback color may be provided to cover the rest of the output.
|
|
_fallback_color_ should be specified as _#RRGGBB_. Alpha is not supported.
|
|
|
|
*output* <name> background|bg <color> solid_color
|
|
Sets the background of the given output to the specified color. _color_
|
|
should be specified as _#RRGGBB_. Alpha is not supported.
|
|
|
|
*output* <name> transform <transform> [clockwise|anticlockwise]
|
|
Sets the background transform to the given value. Can be one of "90", "180",
|
|
"270" for rotation; or "flipped", "flipped-90", "flipped-180", "flipped-270"
|
|
to apply a rotation and flip, or "normal" to apply no transform. The
|
|
rotation is performed clockwise. If a single output is chosen and a
|
|
rotation direction is specified (_clockwise_ or _anticlockwise_) then the
|
|
transform is added or subtracted from the current transform (this cannot be
|
|
used directly in the configuration file).
|
|
|
|
*output* <name> disable|enable
|
|
Enables or disables the specified output (all outputs are enabled by
|
|
default).
|
|
|
|
*output* <name> toggle
|
|
Toggle the specified output.
|
|
|
|
*output* <name> dpms on|off|toggle
|
|
Enables or disables the specified output via DPMS. To turn an output off
|
|
(ie. blank the screen but keep workspaces as-is), one can set DPMS to off.
|
|
|
|
*output* <name> max_render_time off|<msec>
|
|
Controls when sway composites the output, as a positive number of
|
|
milliseconds before the next display refresh. A smaller number leads to
|
|
fresher composited frames and lower perceived input latency, but if set too
|
|
low, sway may not finish compositing in time for display refresh, leading to
|
|
delayed frames.
|
|
|
|
When set to off, sway composites immediately after display refresh,
|
|
maximizing time available for compositing.
|
|
|
|
To adjust when applications are instructed to render, see *max_render_time*
|
|
in *sway*(5).
|
|
|
|
To set this up for optimal latency:
|
|
. Launch some _full-screen_ application that renders continuously, like
|
|
*glxgears*.
|
|
. Start with *max_render_time 1*. Increment by *1* if you see frame
|
|
drops.
|
|
|
|
This setting only has an effect on Wayland and DRM backends, as support for
|
|
presentation timestamps and predicted output refresh rate is required.
|
|
|
|
*output* <name> adaptive_sync on|off
|
|
Enables or disables adaptive synchronization (often referred to as Variable
|
|
Refresh Rate, or by the vendor-specific names FreeSync/G-Sync).
|
|
|
|
Adaptive sync allows clients to submit frames a little to late without
|
|
having to wait a whole refresh period to display it on screen. Enabling
|
|
adaptive sync can improve latency, but can cause flickering on some
|
|
hardware.
