There is supposed to be a "ConnectorNumber" property that you can use to correlate these RandR outputs with physical connectors. https://cgit.freedesktop.org/xorg/proto/randrproto/tree/randrproto.txt?id=cf3272717e08325f69bdbb759ab35cb4d1839fb7#n1931 E.g., on my system, these two are halves of the same mini-DisplayPort connector: DP-0 connected 1920x1200+0+960 (normal left inverted right x axis y axis) 518mm x 324mm _MUTTER_PRESENTATION_OUTPUT: 0 CscMatrix: 65536 0 0 0 0 65536 0 0 0 0 65536 0 EDID: 00ffffffffffff0010ac2ea055574a31 1b12010380342078eeee91a3544c9926 0f5054a54b00714f8180a94001010101 010101010101283c80a070b023403020 360006442100001a000000ff00473237 3348383731314a575520000000fc0044 454c4c20453234385746500a000000fd 00384c1e5311000a202020202020000b BorderDimensions: 4 supported: 4 Border: 0 0 0 0 range: (0, 65535) SignalFormat: TMDS supported: TMDS ConnectorType: DisplayPort ConnectorNumber: 1 _ConnectorLocation: 1 1920x1200 59.95*+ 1600x1200 60.00 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.03 60.00 800x600 75.00 60.32 640x480 75.00 59.94 DP-4 disconnected (normal left inverted right x axis y axis) CscMatrix: 65536 0 0 0 0 65536 0 0 0 0 65536 0 BorderDimensions: 4 supported: 4 Border: 0 0 0 0 range: (0, 65535) SignalFormat: DisplayPort supported: DisplayPort ConnectorType: DisplayPort ConnectorNumber: 1 _ConnectorLocation: 1 > Thanks. > > -- > Nate _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
