[](https://spdx.org/licenses/MIT.html)
wdisplays is a graphical application for configuring displays in Wayland
compositors. It borrows some code from [kanshi]. It should work in any
compositor that implements the wlr-output-management-unstable-v1 protocol,
including [sway]. The goal of this project is to allow precise adjustment of
display settings in kiosks, digital signage, and other elaborate multi-monitor
setups.

# Building
Build requirements are:
- meson
- GTK+3
- epoxy
- wayland-client
```sh
meson build
ninja -C build
sudo ninja -C build install
```
Binaries are not available. Only building from source is supported, and only
if you're using wlroots compiled from master.
# Usage
Displays can be moved around the virtual screen space by clicking and dragging
them in the preview on the left panel. By default, they will snap to one
another. Hold Shift while dragging to disable snapping. You can click and drag
with the middle mouse button to pan. Zoom in and out either with the buttons on
the top left, or by holding Ctrl and scrolling the mouse wheel. Fine tune your
adjustments in the right panel, then click apply.
There are some options available by clicking the menu button on the top left:
- Automatically Apply Changes: Makes it so you don't have to hit apply. Disable
this for making minor adjustments, but be careful, you may end up with an
unusable setup.
- Show Screen Contents: Shows a live preview of the screens in the left panel.
Turn off to reduce energy usage.
- Overlay Screen Names: Shows big names in the corner of all screens for easy
identification. Disable if they get in the way.
# FAQ (Fervently Anticpiated Quandaries)
### What is this?
It's intended to be the Wayland equivalent of an xrandr GUI, like [ARandR].
### Help, I get errors and/or crashes!
Make sure your wlroots is at version 0.7.0 or later.
### I'm using Sway, why aren't my display settings saved when I log out?
Sway, like i3, doesn't save any settings unless you put them in the config
file. See man `sway-output`. If you want to have multiple configurations
depending on the monitors connected, you'll need to use an external program
like [kanshi].

Clients can use this interface to assign the surface_layer role to
wl_surfaces. Such surfaces are assigned to a "layer" of the output and
rendered with a defined z-depth respective to each other. They may also be
anchored to the edges and corners of a screen and specify input handling
semantics. This interface should be suitable for the implementation of
many desktop shell components, and a broad number of other applications
that interact with the desktop.
Create a layer surface for an existing surface. This assigns the role of
layer_surface, or raises a protocol error if another role is already
assigned.
Creating a layer surface from a wl_surface which has a buffer attached
or committed is a client error, and any attempts by a client to attach
or manipulate a buffer prior to the first layer_surface.configure call
must also be treated as errors.
You may pass NULL for output to allow the compositor to decide which
output to use. Generally this will be the one that the user most
recently interacted with.
Clients can specify a namespace that defines the purpose of the layer
surface.
These values indicate which layers a surface can be rendered in. They
are ordered by z depth, bottom-most first. Traditional shell surfaces
will typically be rendered between the bottom and top layers.
Fullscreen shell surfaces are typically rendered at the top layer.
Multiple surfaces can share a single layer, and ordering within a
single layer is undefined.
An interface that may be implemented by a wl_surface, for surfaces that
are designed to be rendered as a layer of a stacked desktop-like
environment.
Layer surface state (size, anchor, exclusive zone, margin, interactivity)
is double-buffered, and will be applied at the time wl_surface.commit of
the corresponding wl_surface is called.
Sets the size of the surface in surface-local coordinates. The
compositor will display the surface centered with respect to its
anchors.
If you pass 0 for either value, the compositor will assign it and
inform you of the assignment in the configure event. You must set your
anchor to opposite edges in the dimensions you omit; not doing so is a
protocol error. Both values are 0 by default.
Size is double-buffered, see wl_surface.commit.
Requests that the compositor anchor the surface to the specified edges
and corners. If two orthoginal edges are specified (e.g. 'top' and
'left'), then the anchor point will be the intersection of the edges
(e.g. the top left corner of the output); otherwise the anchor point
will be centered on that edge, or in the center if none is specified.
Anchor is double-buffered, see wl_surface.commit.
Requests that the compositor avoids occluding an area of the surface
with other surfaces. The compositor's use of this information is
implementation-dependent - do not assume that this region will not
actually be occluded.
A positive value is only meaningful if the surface is anchored to an
edge, rather than a corner. The zone is the number of surface-local
coordinates from the edge that are considered exclusive.
Surfaces that do not wish to have an exclusive zone may instead specify
how they should interact with surfaces that do. If set to zero, the
surface indicates that it would like to be moved to avoid occluding
surfaces with a positive excluzive zone. If set to -1, the surface
indicates that it would not like to be moved to accommodate for other
surfaces, and the compositor should extend it all the way to the edges
it is anchored to.
For example, a panel might set its exclusive zone to 10, so that
maximized shell surfaces are not shown on top of it. A notification
might set its exclusive zone to 0, so that it is moved to avoid
occluding the panel, but shell surfaces are shown underneath it. A
wallpaper or lock screen might set their exclusive zone to -1, so that
they stretch below or over the panel.
The default value is 0.
Exclusive zone is double-buffered, see wl_surface.commit.
Requests that the surface be placed some distance away from the anchor
point on the output, in surface-local coordinates. Setting this value
for edges you are not anchored to has no effect.
The exclusive zone includes the margin.
Margin is double-buffered, see wl_surface.commit.
Set to 1 to request that the seat send keyboard events to this layer
surface. For layers below the shell surface layer, the seat will use
normal focus semantics. For layers above the shell surface layers, the
seat will always give exclusive keyboard focus to the top-most layer
which has keyboard interactivity set to true.
Layer surfaces receive pointer, touch, and tablet events normally. If
you do not want to receive them, set the input region on your surface
to an empty region.
Events is double-buffered, see wl_surface.commit.
This assigns an xdg_popup's parent to this layer_surface. This popup
should have been created via xdg_surface::get_popup with the parent set
to NULL, and this request must be invoked before committing the popup's
initial state.
See the documentation of xdg_popup for more details about what an
xdg_popup is and how it is used.
When a configure event is received, if a client commits the
surface in response to the configure event, then the client
must make an ack_configure request sometime before the commit
request, passing along the serial of the configure event.
If the client receives multiple configure events before it
can respond to one, it only has to ack the last configure event.
A client is not required to commit immediately after sending
an ack_configure request - it may even ack_configure several times
before its next surface commit.
A client may send multiple ack_configure requests before committing, but
only the last request sent before a commit indicates which configure
event the client really is responding to.
This request destroys the layer surface.
The configure event asks the client to resize its surface.
Clients should arrange their surface for the new states, and then send
an ack_configure request with the serial sent in this configure event at
some point before committing the new surface.
The client is free to dismiss all but the last configure event it
received.
The width and height arguments specify the size of the window in
surface-local coordinates.
The size is a hint, in the sense that the client is free to ignore it if
it doesn't resize, pick a smaller size (to satisfy aspect ratio or
resize in steps of NxM pixels). If the client picks a smaller size and
is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the
surface will be centered on this axis.
If the width or height arguments are zero, it means the client should
decide its own window dimension.
The closed event is sent by the compositor when the surface will no
longer be shown. The output may have been destroyed or the user may
have asked for it to be removed. Further changes to the surface will be
ignored. The client should destroy the resource after receiving this
event, and create a new surface if they so choose.

This protocol exposes interfaces to obtain and modify output device
configuration.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible changes
may be added together with the corresponding interface version bump.
Backward incompatible changes are done by bumping the version number in
the protocol and interface names and resetting the interface version.
Once the protocol is to be declared stable, the 'z' prefix and the
version number in the protocol and interface names are removed and the
interface version number is reset.
This interface is a manager that allows reading and writing the current
output device configuration.
Output devices that display pixels (e.g. a physical monitor or a virtual
output in a window) are represented as heads. Heads cannot be created nor
destroyed by the client, but they can be enabled or disabled and their
properties can be changed. Each head may have one or more available modes.
Whenever a head appears (e.g. a monitor is plugged in), it will be
advertised via the head event. Immediately after the output manager is
bound, all current heads are advertised.
Whenever a head's properties change, the relevant wlr_output_head events
will be sent. Not all head properties will be sent: only properties that
have changed need to.
Whenever a head disappears (e.g. a monitor is unplugged), a
wlr_output_head.finished event will be sent.
After one or more heads appear, change or disappear, the done event will
be sent. It carries a serial which can be used in a create_configuration
request to update heads properties.
The information obtained from this protocol should only be used for output
configuration purposes. This protocol is not designed to be a generic
output property advertisement protocol for regular clients. Instead,
protocols such as xdg-output should be used.
This event introduces a new head. This happens whenever a new head
appears (e.g. a monitor is plugged in) or after the output manager is
bound.
This event is sent after all information has been sent after binding to
the output manager object and after any subsequent changes. This applies
to child head and mode objects as well. In other words, this event is
sent whenever a head or mode is created or destroyed and whenever one of
their properties has been changed. Not all state is re-sent each time
the current configuration changes: only the actual changes are sent.
This allows changes to the output configuration to be seen as atomic,
even if they happen via multiple events.
A serial is sent to be used in a future create_configuration request.
Create a new output configuration object. This allows to update head
properties.
Indicates the client no longer wishes to receive events for output
configuration changes. However the compositor may emit further events,
until the finished event is emitted.
The client must not send any more requests after this one.
This event indicates that the compositor is done sending manager events.
The compositor will destroy the object immediately after sending this
event, so it will become invalid and the client should release any
resources associated with it.
A head is an output device. The difference between a wl_output object and
a head is that heads are advertised even if they are turned off. A head
object only advertises properties and cannot be used directly to change
them.
A head has some read-only properties: modes, name, description and
physical_size. These cannot be changed by clients.
Other properties can be updated via a wlr_output_configuration object.
Properties sent via this interface are applied atomically via the
wlr_output_manager.done event. No guarantees are made regarding the order
in which properties are sent.
This event describes the head name.
The naming convention is compositor defined, but limited to alphanumeric
characters and dashes (-). Each name is unique among all wlr_output_head
objects, but if a wlr_output_head object is destroyed the same name may
be reused later. The names will also remain consistent across sessions
with the same hardware and software configuration.
Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do
not assume that the name is a reflection of an underlying DRM
connector, X11 connection, etc.
If the compositor implements the xdg-output protocol and this head is
enabled, the xdg_output.name event must report the same name.
The name event is sent after a wlr_output_head object is created. This
event is only sent once per object, and the name does not change over
the lifetime of the wlr_output_head object.
This event describes a human-readable description of the head.
The description is a UTF-8 string with no convention defined for its
contents. Examples might include 'Foocorp 11" Display' or 'Virtual X11
output via :1'. However, do not assume that the name is a reflection of
the make, model, serial of the underlying DRM connector or the display
name of the underlying X11 connection, etc.
If the compositor implements xdg-output and this head is enabled,
the xdg_output.description must report the same description.
The description event is sent after a wlr_output_head object is created.
This event is only sent once per object, and the description does not
change over the lifetime of the wlr_output_head object.
This event describes the physical size of the head. This event is only
sent if the head has a physical size (e.g. is not a projector or a
virtual device).
This event introduces a mode for this head. It is sent once per
supported mode.
This event describes whether the head is enabled. A disabled head is not
mapped to a region of the global compositor space.
When a head is disabled, some properties (current_mode, position,
transform and scale) are irrelevant.
This event describes the mode currently in use for this head. It is only
sent if the output is enabled.
This events describes the position of the head in the global compositor
space. It is only sent if the output is enabled.
This event describes the transformation currently applied to the head.
It is only sent if the output is enabled.
This events describes the scale of the head in the global compositor
space. It is only sent if the output is enabled.
The compositor will destroy the object immediately after sending this
event, so it will become invalid and the client should release any
resources associated with it.
This object describes an output mode.
Some heads don't support output modes, in which case modes won't be
advertised.
Properties sent via this interface are applied atomically via the
wlr_output_manager.done event. No guarantees are made regarding the order
in which properties are sent.
This event describes the mode size. The size is given in physical
hardware units of the output device. This is not necessarily the same as
the output size in the global compositor space. For instance, the output
may be scaled or transformed.
This event describes the mode's fixed vertical refresh rate. It is only
sent if the mode has a fixed refresh rate.
This event advertises this mode as preferred.
The compositor will destroy the object immediately after sending this
event, so it will become invalid and the client should release any
resources associated with it.
This object is used by the client to describe a full output configuration.
First, the client needs to setup the output configuration. Each head can
be either enabled (and configured) or disabled. It is a protocol error to
send two enable_head or disable_head requests with the same head. It is a
protocol error to omit a head in a configuration.
Then, the client can apply or test the configuration. The compositor will
then reply with a succeeded, failed or cancelled event. Finally the client
should destroy the configuration object.
Enable a head. This request creates a head configuration object that can
be used to change the head's properties.
Disable a head.
Apply the new output configuration.
In case the configuration is successfully applied, there is no guarantee
that the new output state matches completely the requested
configuration. For instance, a compositor might round the scale if it
doesn't support fractional scaling.
After this request has been sent, the compositor must respond with an
succeeded, failed or cancelled event. Sending a request that isn't the
destructor is a protocol error.
Test the new output configuration. The configuration won't be applied,
but will only be validated.
Even if the compositor succeeds to test a configuration, applying it may
fail.
After this request has been sent, the compositor must respond with an
succeeded, failed or cancelled event. Sending a request that isn't the
destructor is a protocol error.
Sent after the compositor has successfully applied the changes or
tested them.
Upon receiving this event, the client should destroy this object.
If the current configuration has changed, events to describe the changes
will be sent followed by a wlr_output_manager.done event.
Sent if the compositor rejects the changes or failed to apply them. The
compositor should revert any changes made by the apply request that
triggered this event.
Upon receiving this event, the client should destroy this object.
Sent if the compositor cancels the configuration because the state of an
output changed and the client has outdated information (e.g. after an
output has been hotplugged).
The client can create a new configuration with a newer serial and try
again.
Upon receiving this event, the client should destroy this object.
Using this request a client can tell the compositor that it is not going
to use the configuration object anymore. Any changes to the outputs
that have not been applied will be discarded.
This request also destroys wlr_output_configuration_head objects created
via this object.
This object is used by the client to update a single head's configuration.
It is a protocol error to set the same property twice.
This request sets the head's mode.
This request assigns a custom mode to the head. The size is given in
physical hardware units of the output device. If set to zero, the
refresh rate is unspecified.
It is a protocol error to set both a mode and a custom mode.
This request sets the head's position in the global compositor space.
This request sets the head's transform.
This request sets the head's scale.

This protocol allows clients to ask the compositor to copy part of the
screen content to a client buffer.
Warning! The protocol described in this file is experimental and
backward incompatible changes may be made. Backward compatible changes
may be added together with the corresponding interface version bump.
Backward incompatible changes are done by bumping the version number in
the protocol and interface names and resetting the interface version.
Once the protocol is to be declared stable, the 'z' prefix and the
version number in the protocol and interface names are removed and the
interface version number is reset.
This object is a manager which offers requests to start capturing from a
source.
Capture the next frame of an entire output.
Capture the next frame of an output's region.
The region is given in output logical coordinates, see
xdg_output.logical_size. The region will be clipped to the output's
extents.
All objects created by the manager will still remain valid, until their
appropriate destroy request has been called.
This object represents a single frame.
When created, a "buffer" event will be sent. The client will then be able
to send a "copy" request. If the capture is successful, the compositor
will send a "flags" followed by a "ready" event.
If the capture failed, the "failed" event is sent. This can happen anytime
before the "ready" event.
Once either a "ready" or a "failed" event is received, the client should
destroy the frame.
Provides information about the frame's buffer. This event is sent once
as soon as the frame is created.
The client should then create a buffer with the provided attributes, and
send a "copy" request.
Copy the frame to the supplied buffer. The buffer must have a the
correct size, see zwlr_screencopy_frame_v1.buffer. The buffer needs to
have a supported format.
If the frame is successfully copied, a "flags" and a "ready" events are
sent. Otherwise, a "failed" event is sent.
Provides flags about the frame. This event is sent once before the
"ready" event.
Called as soon as the frame is copied, indicating it is available
for reading. This event includes the time at which presentation happened
at.
The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples,
each component being an unsigned 32-bit value. Whole seconds are in
tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo,
and the additional fractional part in tv_nsec as nanoseconds. Hence,
for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part
may have an arbitrary offset at start.
After receiving this event, the client should destroy the object.
This event indicates that the attempted frame copy has failed.
