+1. Introduction
+
+The X Resize, Rotate and Reflect Extension, called RandR for short,
+brings the ability to resize, rotate and reflect the root window of a
+screen. It is based on the X Resize and Rotate Extension as specified
+in the Proceedings of the 2001 Usenix Technical Conference [RANDR].
+
+RandR as implemented and integrated into the X server differs in
+one substantial fashion from the design discussed in that paper: that
+is, RandR 1.0 does not implement the depth switching described in that
+document, and the support described for that in the protocol in that
+document and in the implementation has been removed from the
+protocol described here, as it has been overtaken by events.
+
+These events include:
+      ► Modern toolkits (in this case, GTK+ 2.x) have progressed to the point
+        of implementing migration between screens of arbitrary depths
+      ► The continued advance of Moore's law has made limited amounts of VRAM
+        less of an issue, reducing the pressure to implement depth switching
+	on laptops or desktop systems
+      ► The continued decline of legacy toolkits whose design would have
+        required depth switching to support migration
+      ► The lack of depth switching implementation experience in the
+        intervening time, due to events beyond our control
+
+Additionally, the requirement to support depth switching might
+complicate other re-engineering of the device independent part of the
+X server that is currently being contemplated.
+
+Rather than further delaying RandR's widespread deployment for a feature
+long wanted by the community (resizing of screens, particularly on laptops),
+or the deployment of a protocol design that might be flawed due to lack of
+implementation experience, we decided to remove depth switching from the
+protocol. It may be implemented at a later time if resources and
+interests permit as a revision to the protocol described here, which will
+remain a stable base for applications. The protocol described here has been
+implemented in the main X.org server, and more fully in the hw/kdrive
+implementation in the distribution, which fully implements resizing,
+rotation and reflection.
+
+1.2 Introduction to version 1.2 of the extension
+
+One of the significant limitations found in version 1.1 of the RandR
+protocol was the inability to deal with the Xinerama model where multiple
+monitors display portions of a common underlying screen. In this environment,
+zero or more video outputs are associated with each CRT controller which
+defines both a set of video timings and a 'viewport' within the larger
+screen. This viewport is independent of the overall size of the screen, and
+may be located anywhere within the screen.
+
+The effect is to decouple the reported size of the screen from the size
+presented by each video output, and to permit multiple outputs to present
+information for a single screen.
+
+To extend RandR for this model, we separate out the output, CRTC and screen
+configuration information and permit them to be configured separately. For
+compatibility with the 1.1 version of the protocol, we make the 1.1 requests
+simultaneously affect both the screen and the (presumably sole) CRTC and
+output. The set of available outputs are presented with UTF-8 encoded names
+and may be connected to CRTCs as permitted by the underlying hardware. CRTC
+configuration is now done with full mode information instead of just size
+and refresh rate, and these modes have names. These names also use UTF-8
+encoding. New modes may also be added by the user.
+
+Additional requests and events are provided for this new functionality.

+
+In this picture, the screen is covered (incompletely) by two CRTCs. CRTC1
+is connected to two outputs, A and B. CRTC2 is connected to output C.
+Outputs A and B will present exactly the same region of the screen using
+the same mode line. Output C will present a different (larger) region of
+the screen using a different mode line.
+
+RandR provides information about each available CRTC and output; the
+connection between CRTC and output is under application control, although
+the hardware will probably impose restrictions on the possible
+configurations. The protocol doesn't try to describe these restrictions,
+instead it provides a mechanism to find out what combinations are supported.
+
+For instance, dual-link DVI gangs two CRTC outputs together to provide higher
+bandwidth for large resolution screens. This is exposed in RandR by
+requiring that nothing be connected to the second CRTC when driving a high
+resolution screen on the first.
+
+1.3 Introduction to version 1.3 of the extension
+
+Version 1.3 builds on the changes made with version 1.2 and adds some new
+capabilities without fundmentally changing the extension again. The
+following features are added in this version:
+
+   • Projective Transforms. The implementation work for general rotation
+     support made it trivial to add full projective transformations. These
+     can be used to scale the screen up/down as well as perform projector
+     keystone correct or other effects.
+
+   • Panning. It was removed with RandR 1.2 because the old semantics didn't
+     fit any longer. With RandR 1.3 panning can be specified per crtc.

+
+2. Screen change model
+
+Screens may change dynamically, either under control of this extension, or
+due to external events. Examples include: monitors being swapped, pressing a
+button to switch from internal display to an external monitor on a laptop,
+or, eventually, the hotplug of a display card entirely on busses such as
+Cardbus or Express Card which permit hot-swap (which will require other work
+in addition to this extension).
+
+Since the screen configuration is dynamic and asynchronous to the client and
+may change at any time RandR provides mechanisms to ensure that your clients
+view is up to date with the configuration possibilities of the moment and
+enforces applications that wish to control the configuration to prove that
+their information is up to date before honoring requests to change the
+screen configuration (by requiring a timestamp on the request).
+
+Interested applications are notified whenever the screen configuration
+changes, providing the current size of the screen and subpixel order (see
+the Render extension [RENDER]), to enable proper rendering of subpixel
+decimated client text to continue, along with a time stamp of the
+configuration change. A client must refresh its knowledge of the screen
+configuration before attempting to change the configuration after a
+notification, or the request will fail.
+
+To avoid multiplicative explosion between orientation, reflection and sizes,
+the sizes are only those sizes in the normal (0) rotation.
+
+Rotation and reflection and how they interact can be confusing. In Randr,
+the coordinate system is rotated in a counter-clockwise direction relative
+to the normal orientation. Reflection is along the window system coordinate
+system, not the physical screen X and Y axis, so that rotation and
+reflection do not interact. The other way to consider reflection is to is
+specified in the "normal" orientation, before rotation, if you find the
+other way confusing.
+
+We expect that most clients and toolkits will be oblivious to changes to the
+screen structure, as they generally use the values in the connections Display
+structure directly. By toolkits updating the values on the fly, we believe
+pop-up menus and other pop up windows will position themselves correctly in
+the face of screen configuration changes (the issue is ensuring that pop-ups
+are visible on the reconfigured screen).
+
+                              ❧❧❧❧❧❧❧❧❧❧❧
+
+3. Data Types
+
+The subpixel order is shared with the Render extension, and is documented
+there. The only datatype defined is the screen size, defined in the normal
+(0 degree) orientation.

+
+Errors are sent using core X error reports.
+
+Output
+	A value for an OUTPUT argument does not name a defined OUTPUT.
+CRTC
+	A value for a CRTC argument does not name a defined CRTC.
+Mode
+	A value for a MODE argument does not name a defined MODE.

+
+5. Protocol Types
+
+RRCONFIGSTATUS { Success
+		 InvalidConfigTime
+		 InvalidTime
+		 Failed }
+
+	A value of type RRCONFIGSTATUS returned when manipulating the output
+	configuration or querying information from the server that has some
+	time-dependency.
+
+	InvalidConfigTime indicates that the supplied configuration
+	timestamp does not match the current X server configuration
+	timestamp. Usually this means that the output configuration has
+	changed since the timestamp was received by the application.
+
+	InvalidTime indicates that the supplied output reconfiguration time
+	is earlier than the most recent output reconfiguration request.
+	Generally this indicates that another application has reconfigured
+	the output using a later timestamp.
+
+	Failed is returned whenever the operation is unsuccessful for some
+	other reason. This generally indicates that the requested output
+	configuration is unsupported by the hardware. The goal is to make
+	these limitations expressed by the protocol, but when that isn't
+	possible it is correct to return this error value. If, as a
+	implentor, you find this error code required, please submit the
+	hardware constraints that exist so that a future version of the
+	extension can correctly capture the configuration constraints in
+	your system.
+
+ROTATION { Rotate_0
+	   Rotate_90
+	   Rotate_180
+	   Rotate_270
+	   Reflect_X
+	   Reflect_Y }
+
+	These values are used both to indicate a set of allowed rotations
+	and reflections as well as to indicate a specific rotation and
+	reflection combination.

+7.1. Extension Requests added in version 1.2 of the extension
+
+As introduced above, version 1.2 of the extension splits the screen size
+from the crtc and output configuration, permitting the subset of the screen
+presented by multiple outputs to be configured. As a separate notion, the
+size of the screen itself may be arbitrarily configured within a defined
+range. As crtcs and outputs are added and removed from the system, the set
+returned by the extension will change so that applications can detect
+dynamic changes in the display environment.

+9. Properties
+
+Properties are used for output specific parameters, and for announcing
+static or rarely changing data.  Announced data is typically
+immutable.  Properties are also used for evaluating new parameters
+before adding them to the RandR protocol.
+
+The following properties are hereby declared official, and drivers SHOULD
+prefix driver specific properties with '_', unless they are planned to be
+added to this specification.  List values, that are not declared by the table
+below, and will remain driver specific or are not planned to be added to this
+specification, SHOULD be prefixed with "_" as well in order to avoid name
+space or semantics clashes with future extensions of these values.
+
+Beginning with version 1.3 of the RandR extension, certain properties
+are mandatory and MUST be provided by implementations.  Earlier
+versions of the RandR extension MAY provide these properties as well,
+as long as the semantics are not altered.  Clients SHOULD fall back
+gracefully to lower version functionality, though, if the driver
+doesn't handle a mandatory property correctly.

+
+10. Extension Versioning
+
+The RandR extension was developed in parallel with the implementation
+to ensure the feasibility of various portions of the design. As
+portions of the extension are implemented, the version number of the
+extension has changed to reflect the portions of the standard provided.
+This document describes the version 1.2 of the specification, the
+partial implementations have version numbers less than that. Here's a
+list of what each version provided:
+
+	0.0: This prototype implemented resize and rotation in the
+	     TinyX server Used approximately the protocol described in
+	     the Usenix paper. Appeared in the TinyX server in
+	     XFree86 4.2, but not in the XFree86 main server.
+
+	0.1: Added subpixel order, added an event for subpixel order.
+	     This version was never checked in to XFree86 CVS.
+
+	1.0: Implements resize, rotation, and reflection. Implemented
+	     both in the XFree86 main server (size change only at this
+	     date), and fully (size change, rotation, and reflection)
+	     in XFree86's TinyX server.
+
+	1.1: Added refresh rates
+
+	1.2: Separate screens from CRTCs and outputs, switch to full VESA
+	     modes
+
+	1.3: Added cheap version of RRGetScreenResources.  Added CRTC
+	     transformations.  Added panning.  Added primary outputs.
+	     Added standard properties.
+
+Compatibility between 0.0 and 1.0 was *NOT* preserved, and 0.0 clients
+will fail against 1.0 servers. The wire encoding op-codes were
+changed for GetScreenInfo to ensure this failure in a relatively
+graceful way. Version 1.1 servers and clients are cross compatible with
+1.0. Version 1.1 is considered to be stable and we intend upward
+compatibility from this point. Version 1.2 offers an extended model of the
+system with multiple output support. Version 1.3 adds a cheap version of
+GetScreenResources to avoid expensive DDC operations, CRTC transformations,
+panning, and the primary output concept. 1.2 and 1.3 are backward-compatible
+with 1.1.
+
+                              ❧❧❧❧❧❧❧❧❧❧❧
+
+11. Relationship with other extensions
+
+Two other extensions have a direct relationship with this extension. This
+section attempts to explain how these three are supposed to work together.
+
+11.1 XFree86-VidModeExtension
+
+XFree86-VidModeExtension changes the configuration of a single monitor
+attached to the screen without changing the configuration of the screen
+itself. It provides the ability to specify new mode lines for the server to
+use along with selecting among existing mode lines. As it uses screen
+numbers instead of window identifiers, it can be used to affect multiple
+monitors in a single-screen Xinerama configuration. However, the association
+between screen numbers and root windows in a multi-Screen environment is not
+defined by the extension. Version 2.0 of this extension added the ability to
+adjust the DAC values in a TrueColor server to modify the brightness curves
+of the display.
+
+All of the utility of this extension is subsumed by RandR version 1.2, RandR
+should be used in preference to XFree86-VidModeExtension where both are
+present.
+
+11.2 Xinerama
+
+Xinerama provides a mechanism for describing the relationship between the
+overall screen display and monitors placed within that area. As such, it
+provides the query functionality of RandR 1.2 without any of the
+configuration functionality. Applications using Xinerama to discover
+monitor geometry can continue to do so, with the caveat that they will not be
+informed of changes when they occur. However, Xinerama configuration data
+will be updated, so applications selecting for RandR notification and
+re-querying the configuration with the Xinerama extension will get updated
+information. It is probably better to view RandR as a superset of Xinerama
+at this point and use it in preference to Xinerama where both are present.
