Before this commit (rev 249040), here is an extract of my /var/log/Xorg.log regarding the probing part on DP1 connector: [ 45.194] (II) intel(0): EDID for output DP1 [ 45.194] (II) intel(0): Manufacturer: ACI Model: 24b1 Serial#: 168430= 09 [ 45.194] (II) intel(0): Year: 2012 Week: 23 [ 45.194] (II) intel(0): EDID Version: 1.4 [ 45.194] (II) intel(0): Digital Display Input [ 45.194] (II) intel(0): 8 bits per channel [ 45.194] (II) intel(0): Digital interface is DisplayPort [ 45.194] (II) intel(0): Max Image Size [cm]: horiz.: 55 vert.: 35 [ 45.194] (II) intel(0): Gamma: 2.20 [ 45.194] (II) intel(0): DPMS capabilities: Off [ 45.194] (II) intel(0): Supported color encodings: RGB 4:4:4 YCrCb 4:4:4 YCrCb 4:2:2 [ 45.194] (II) intel(0): First detailed timing is preferred mode [ 45.194] (II) intel(0): Preferred mode is native pixel format and refresh rate [ 45.194] (II) intel(0): redX: 0.637 redY: 0.331 greenX: 0.304 greenY: 0.626 [ 45.194] (II) intel(0): blueX: 0.152 blueY: 0.071 whiteX: 0.313 whiteY: 0.329 (etc...)
