TV, TV‐SCART, TV‐Component, - and TV‐C4 with signal format VGA are valid combinations and describe - RGB TV signals. - - "ConnectorNumber" aka RR_PROPERTY_CONNECTOR_NUMBER - Type: int32 - Flags: Immutable, Static - Range/List: 0- - - Outputs that route their signal to the same connector MUST - have the same connector number. Outputs with the same - connector number MUST route their signal to the same - connector, except if it is 0, which indicates unknown - connectivity. 1 is called the primary connector, 2 the - secondary. 3 is typically a TV connector, but that is completely - driver / hardware dependent. - Outputs with the same connector number SHOULD have the same - connector type. Meaning and client behavior for mismatching - connector types is undefined at the moment. - - "CompatibilityList" aka RR_PROPERTY_COMPATIBILITY_LIST - Type: int32 [2*n] / Atom pairs - Flags: Immutable - Range/List: 0- - - Some combinations of outputs on some cards cannot be served at all, - because the according encoder is only capable of driving one output at - a time. - This property lists all output + signal format pairs that can be - driven together with this output. NULL atoms specify any output / any - signal format, respectively. - This property MUST be symmetric, but may change with changing signal - format. I.e. if the property for DVI-1/TMDS specifies VGA-1/VGA to be - available, VGA-1/VGA has to list DVI-1/TMDS as well. - - "CloneList" aka RR_PROPERTY_CLONE_LIST - Type: int32 [2*n] / Atom pairs - Flags: Immutable - Range/List: 0- - - Some combinations of outputs on some cards cannot be served - independently from each other, because they are wired up to the same - encoder outputs. - This property lists all output + signal format pairs that are - driven together with this output, and thus can only be programmed in - clone mode with the same CRTC. - This property MUST be symmetric, but may change with changing signal - format. I.e. if the property for DVI-1/VGA specifies VGA-1/VGA to be - cloned, VGA-1/VGA has to list DVI-1/VGA as well. - Outputs / format pairs listed in this property MUST be included in the - CompatibilityList. - 9.2 Properties introduced with version 1.2 of the RandR extension Property Immutable Mandatory since ──────── ───────── ─────────────── -EdidData yes n/a +EDID yes n/a -EdidData is provided by the RandR frontend, thus not driver specific. +EDID is provided by the RandR frontend, thus not driver specific. 9.3 Properties introduced with version 1.3 of the RandR extension Property Immutable Mandatory since ──────── ───────── ─────────────── +CloneList yes not mandatory +CompatibilityList yes not mandatory +ConnectorNumber yes: static not mandatory +ConnectorType yes: static RandR 1.3 SignalFormat no RandR 1.3 SignalProperties no not mandatory -ConnectorType yes: static RandR 1.3 -ConnectorNumber yes: static not mandatory -CompatibilityList yes not mandatory -CloneList yes not mandatory + +9.4 Properties introduced with version 1.4 of the RandR extension + +Property Immutable Mandatory since +──────── ───────── ─────────────── +Backlight no not mandatory ❧❧❧❧❧❧❧❧❧❧❧ @@ -1655,7 +1667,7 @@ A.1 Common Types 0x0008 OutputPropertyNotifyMask Added in version 1.2 └─── Event select mask for RRSelectInput - + ┌─── RRCONFIGSTATUS 0x0 Success @@ -1664,7 +1676,7 @@ A.1 Common Types 0x3 Failed └─── Return status for requests which depend on time. - + ┌─── MODEINFO (32) Added in version 1.2 4 CARD32 id @@ -1681,7 +1693,7 @@ A.1 Common Types 2 CARD16 name length 4 SETofMODEFLAG mode flags └─── - + An output mode specifies the complete CRTC timings for a specific mode.
